This is one of the best DIY videos I’ve seen! You take your time to explain and assure no steps is missing. Most of the video is with clear sound and crisp pictures. Extremely helpful for everyone with this fault (including me). Thank you!👏🏻⭐️
So glad I’ve found this video. I drove 125 miles yesterday mainly motorway and my golf 1.6tdi went into limp mode a mile from home. Managed to get an OBDII reader and confirmed p0201 code. Now just got to sell a kidney to fund the new injector- cheapest (only one) available is £505 and that’s with a 45% discount 😢😲. Watching this video has given me the confidence to replace it myself. Just have to source the kit to recode the ECU
All right bud see your post if you try a place called: Carwood, descent price for my injector (caddy 1.6tdi only £330🤢🤮) don't know if your will be in stock tho.
Hi, fantastic detailed video, I have the same injector problem on cylinder 4 on my golf, I feel more confident to tackle it now I have watched your filming. also glad you showed how to test a faulty injector with the multimeter. keep up the good work.
Thank you for the lovely message. This is the reason I make my videos. I am glad people are finding my content helpful as this makes my effort worthwhile. 🔩🔧🤝
A very thorough job done, Cleaning out the old seals & seats for the replacement injectors, good that you thought to test the replacement injector, before fitting into the engine, and it showed no fault lights or codes. I not sure if most mechanics would go to the trouble. Very good. You should work for VW. My car has done 80,000 so may need to do that job in the near future. Well Done.
Awesome video! Did everything myself and went amazing. Injector was €420 and called VW for the clamp bolt and O-rings and they were about €7. Used a torque wrench just like you did and everything went well! Car started right up with no issues. Afterwards i just had my friend code the injector with his Autel unit. Thank you so much!
@@kbpower4086 It is not called programming, it is called coding. I explain it in great detail in the video. You need to code the injector in order to tell the computer the calibrating values of the injector so it knows the tolerances. You can clear the faults after the job is done. Hope this helps
@@TheKeenMechanic Great. Thank you. Will try download the software to be able to do this. I have the OBD II Reader and was able to fix the car after getting error code P0203 (injector 3) and tested it to be 8ohm. The other three were 200k ohm. Your video helped me a lot. Thanks again
Great Video, Thanks to you, Im now confident to repair it for myself. I had exactly your problem and also measured the resistance and my second injector is faulty, also had the 606 code.
@@TheKeenMechanic didnt last long cause now after the swap and coding the engine makes strange noise if I accelerate. I think it should be properly coded
Thank you for this video. I recently had no.2 injector go and this helped me diagnose and solve with a second hand injector. The step by step and socket sizes helped me greatly.
Great video ! I was able to repair the car 135km from home. Replaced the bad injector, cleared the faults and recoded the new injector value. Thank you so much, worked like a charm :-)
I am very happy to hear that my video was helpful to you. I did it because I know it is causing a lot of trouble this 1.6tdi motor and these injectors ...277b are very unreliable. I believe the new updated injectors with part number ...277s are better but very expensive still at 250-300 a piece. Thanks for taking the time to leave a comment. 🤝
@@TheKeenMechanic Is it possible to replace a single 277B injector with a 277S injector? Is it possible to operate three 277B injectors with one 277 S injector?
@@iulianplumbu1034 I personally haven't done it but I don't a reason why it shouldn't work. It is the same spec injector only inproved part so piezo element wont fail prematurely🤝
Simply amazing! Thank you! Read exactly the same error with obd eleven and it is the exact same engine on a skoda 2011. Obd eleven recommends your vid 😁
This is exactly what problem I had with my car and believe you saved me a lot by trying to find the fault in my car thank you for posting this is been really helpful hope you help others who watch this video to 👍
Hi. I have a 2010 sdi caddy. Got my van back yesterday and now have a engine management light on. Garage I first took it to said egr code was coming up, so took it to a diesel specialist who didnt plug it in & tested the injectors instead and said that's the problem. Then took it to auto electricians to sort out abs look, in receiving it back he said he plugged his box in and egr valve fault.
Your video is gold.. thanks for sharing! By the way, do you think that it's possible that the resistance problem of the injector can be fixed by simply changing the electronic part of the injector? Or is it a consequence of a damage of the injector so it has to be changed all over? Thanks!
Hi and thanks for your comment. The problem with these injectors is the piezo element which is the electronic part. The piezo element can be replaced but it is not cheap and needs calibaration on a bench after replacing. I left a very detailed reply to one of the questions from another subscriber. Please check below. I am glad you found it very helpful
Veryhelpful, just got injector problem on my golf, the car let me down on the road, very helpful video Will be nice if you can share from were you purchase the recon injector, maybe the pn for the stud and other needed parts
Today i got my car back from the garage. VW Golf 1.6 CAYC 2012. They replaced the second injector. This was also the second one replaced on my car. The first one was replaced 3 years ago. I read your comment about the partnumbers from the unreliable types of injector. Is the 277b the only unreliable series? Where can i find these part numbers? I want to know if there are more injectors of the unreliable types on my engine… Thank you for the very informative video!
The code is on the top of the injector. It is printed on the black piezo electrical part where the calibration code is printed as well. You will see also like an QR code. It is all in the same place. If you can afford replace with new 03L130277S injectors. Hope this helps.
It will run but not as well as if it is coded. If previous injector that was coded there has similar calibrating value you might be lucky. I personally would get it coded
Hi Did you replace the injectors with used or new injectors? I had luck with this one, still going with no issues. Only cost me £70, not sure how long it will last though. One thing I was told to do is to remove the plastic engine cover to help the injectors stay cooler. Not sure if this is helping but as I said no issues so far after the repair. Thanks for your comment and for watching my video
@@TheKeenMechanic i bought new ones for pistons 1 and 3, i have them for over a year now but since i replaced the one on piston 3 the engine when i accelarate vibrates alot
It might be worth doing a back leak test on all just to make sure there is no blockage on any of the injectors. Did you code them after replacement. Also check for other faults stored in ecu
Firstly, tighten the injector clamp bolt 1 to 2 Nm, then tighten the high pressure lines BEFORE torquing down the new injector clamp bolt to 8Nm + 270 degrees.
What if car was remapped and after that 1 injector was replaced is still necessary to add new injector into ECU ? will that cause any problem as other injectors was remapped and recently replaced one wasn't? or that doesn't reflect on earlier done remap ? Thanks for your help , watching your video helped me allot and today i've replaced my faulty injector!
Thanks for this video I’m currently going through the same on my 1.6 Ibiza on injector 4 however my machine allows me to clear the code and it runs well for a while all be it an odd misfire then after a while the glow light appears again after about 5 miles driving I’m starting to think this is another issue elsewhere… I can’t test resistance at the min as my multimeter isn’t working
Thank you very much for the video. It will be very very helpful for me. Do you have an updated link for the Wow because I need to buy one and I want to make sure it will work for injector programmation ? Than you for your help
Great video, thank you for this. I seems to have a similar problem on my Skoda Fabia 1.6 tdi cayb - P0204 injector circut error. I did the resistance check and weird thing happened. I ran the test twice. First time coil 1,2, 3 - 200kOMs, coil 4 - close to 0. Second run - all coils close to 0...The time between the tests was like 10 minutes and I did not start the engine in between. What can be the reason for that? Should this test be run under pressure? I also did the second testing with unplugging the wiring on the injectors while engine is running. To my surprise, however I am not an expert on mechanics, I think when unplugging each injector the engine seemed to be suffering. I did not observe that unplugging injector 4 would have no effect on the engine. Not sure where to go from here.
Hi Thanks for watching my video. Don't worry. I will help you with this. If you have P0204 and no other faults then your other injectors are ok for now. The fact that you can still start the engine means that most injectors are working. Your problem is clearly your injector 4. It is good you did all the testing that I have shown in the video to help me determine the problem. When reading the resistance in OHMS it can happen that if your test leads don't have good contact you can get different readings. I would say you can replace the injector 4 and even before installation plug it in in the electric socket as I did show to see if it will clear the fault. This will save you some work in case you buy a faulty injector. If buying used injector from a breaker make sure you bring your multimeter with you and test the resistance before you pay. Best job is to buy brand new updated version 277s. For more information read all comments below as I have described this to other people below in the comments. Let me know how you get on
The Keen Mechanic thank you for prompt answer! I am planning to do the injector 4 change, but what I am trying to do is to isolate the problem first. And I struggle to understand, if the injector 4 is the problem, why when unplugging it, the engine is clearly struggling. I assume that if it gone bad, there would be no impact on the engine when unplugging it. Few days ago I also visited local mechanic and he also tested the coils only and with use of his device his opinion was that all coils are basically dead. I am struggling to believe that all went bad at the same time. Did that ever happen to you? I just redid the resistance test and the multimeter shows 0.00 on all coils when stabilizing the leads. I am worried that even if I replace the injector 4, the problem will stay 😢 The engine is working fine when starting with everything plugged. Is it possible that problem is somewhete else? EGR valve or DPF?
Hi This is very unusual indeed. If the engine starts than your injectors are ok. The piezo elements (coils) are also good too otherwise the injectors won't work and engine wont start. Please check all your wiring as this is very unusual. Even if the piezo elements (coils) are faulty in all my cases I was still getting some readings (never 0) I know that these engines suffer from EGR problem and I did fix this years ago but unfortunately I don't remember what fault code I got. Check all cables and also all fuses first. Don't give up easily as you just need to think logically. Clearly your fault is electrical and you can isolate other issues. Check on youtube for the egr issue, if I remember correctly it was the little moving arm that gets clogged and damaged and won't move the flap inside. In my case I just blocked the EGR and ordered a chip online to eliminate the faults on the dash and never had issues ever again with the EGR. This was the easy fix as these EGRs are water cooled and very hard to access if you decide to replace it with a new one. Let me know how you progress buddy. Hope this helps
Hello. For info I think after doing research that humidity must participate in the failure of the piezo. On my injectors and especially the broken one, the top was quite rusty. I found this: Humidity is a serious piezo killer High humidity, e.g. 85% RH is a serious condition, which shorten the life of the actuator. Make sure that humidity level is kept low - best is hermetically sealed applications. Consult Noliac if actuators must work at high humidity.
Hi and thanks for watching and for taking your time to leave a comment. I had the same question from one of my subscribers. Please see my response to Johs4490 It cost him 650 euro in Germany
Hello I am doing it, I managed to take them apart !! two questions: -Since you only change one, you have to change the gasket on the other (copper) -I find the bottom of the injector that I leave with the new one very dirty. Did you clean it? Thanks for your quick response, I'm hard at work.
I am very proud that my video helped you decide to do it yourself. Yes, replace both copper seals on both injectors and gently clean the carbon of the tip of the injector. You will be fine, just take your time and make sure you code the injector after you do the job. You can do the coding at any point🤝
@@TheKeenMechanic Ok I'll change the seal. To clean the carbon, you have to use a product because with a cloth it does not come off? Brake cleaner? Otherwise this injector worked but I do not see the holes at the end, I wonder how it still works!
@@F5SSL I didnt see the holes in mine too even after the cleaning but it worked. Just do a bit more research on this and let me know what you find. Google ultrasonic cleaners
Hello. Before I started, I had another question. Should the injectors be removed with the engine hot or cold? What's your opinion? (I think it must be hot)
Good morning mate I need to do same job on my sisters car, I just had a question since last few week she keep getting the DPF sign on where it wasn't passively regenerating. So had to always actively regenerate. Now found this error when called RAC they said needs new injector. Will it solve the DPF issue?
Not 100% sure mate, but I know the engine regenerates by raising the heat by injecting more fuel. If your injector is not working correctly may be it is not helping with the temperature increase but again this is just me thinking outloud. Do an indepth research online or ask a local injector specialist
What a superb video. You have helped me enormously. I thought you had to program the injector in some way - apparently not. Also where did you source your used injector please? Thank you very much indeed
Try it but make sure they offer some warranty. I used 2nd hand and died after less than 10k miles, then remanufactured and is still going but if you can afford new this is the best option
I got P0201 error on Touran 1.6 TDI and I measured all four injectors where all four show same resistance. Could still the first one be faulty despite correct resistance? Second thing I'm suspecting could be wiring. Thank you in advance for any suggestion.
Hi. Swap the injectors from 1 and 2 and see if the problem moves to 2. Do that after you have checked your wiring and make sure the ohms readings are as shown in the video. Any deviation from 200 would be a faulty injector
I drove 80miles (130kilometres) in mine on 3 cylinders and got home. Hope nothing goes wrong for you if you do the same as myself. Get it fixed as soon as possible. Best of luck
Did you need to do adaptation after coding it buddy? I have changed all 4 but the mechanics forgot to code it and now looking for someone els to do it as I don’t trust him anymore as the car been shaking and reving it self when it’s parked with it switched on since I got the injectors replaced
Hi I just coded the injector and never had any issues after that. I find that if you buy refurbished injectors there could be 50/50 good and bad experience. Brand new is your best bet but they are expensive. Second hand would be the worst choice as you dont know how long they will last. Hope this helps
@@TheKeenMechanic i will be following your guide when my injectors die for sure , great guide have you done the auxiliary belt and tensioners on one of these mine need doing soon
@@TheKeenMechanic brilliant! any advice on the best kit to use for the auxiliary, cambelts been doin recently by old owner be auxiliary and tensioner looks old
@@roostaraver no special tools needed there. Just put a socket on the tensionning pulley and release the belt, then put on new one and you are good to go🤝
can the resistance vary between cars? because I checked the 2nd injector which works and it had like 140 or 160 k ohm and the third one which has failed had 5 k ohms
I have had variations myself and they worked. Try to re-use what is good and running as sometimes the multimeter can give different readings. 5k ohms is an indication that is no good
It is very important, but your injector will still work even if you don't code it. It will work better as the engine will know the calibration tolerances🤓🤝
@@TheKeenMechanic Thanks my friend, great video. I just want to take them off to have them professionally cleaned. Exactly same car as yours only recently started having minor injection issues despite always using Shell never supermarket fuel and also additives like hydrablast (I'm assuming as coil light came on was due to injectors with po related fault codes) although did liquid Moly diesel purge and noticed filter became darker so hopefully caught some dirt. If I also knew about dpf problems never would have bought a diesel. I now use vagdpf app to keep track of dpf to go on the motorway before the warning light comes on, usually at 83% full it allows a regen to start at over 2k revs and also had dpf removed and cleaned with Wynn's off dpf solution cleaner.
I think you are right mate. I was wondering if it will throw the code when ignition on and if it senses that there is an issue with the injector wiring
Hello I broke down with a p0402 code, the garage started the car a day later and put diesel treatment inside the car and it runs fine now, took for a run and it runs fine, but I’m worried if I drive far for an hour it will breakdown again, will this happen? The car runs fine and does not misfire, also starts fine, thank you and great vid
@@nazimrashid8611 Hi P0204 relates to injector number 4. I would recommend to check with VW main dealer to see if there is a recall for these injectors. I had one of my subscribers messaging me and told me that his uncle had the injectors replaced for free due to the recall. If VW don't offer any help you can risk to get stuck on the road again if the injector fails again. Normally this code relates to an electrical fault rather that the injector being blocked. Best thing to do is to replace them with new bosch injectors if VW doesn't help but I know it will be expensive. Hope this helps
Hi They are held in place with the same bracket so you may find it easier to remove both otherwise you can bend something if you force it without lifting both at the same time. Use this opportunity to clean both holes and replace both copper seals. Hope this helps
@@mikeyoakes180 Hi Do a search on google and see what comes up. Injectors are separate from glow plugs so not sure why you think it might be related. 🤝
@@TheKeenMechanic hi I’ve replaced the glow plug! I’ve checked on the multi-metre and the injectors seem fine! But it’s still coming up with p0202! Is that definitely the injector do you think?
Hi Check out the comment below for more info. One guy in Czech Republic can replace the piezo element but this is a specialist job as you need special stand to adjust it and calibrate it. My advice is to buy a new🤝
@@TheKeenMechanic I replaced the defective injector with a used one. Injection amount deviation cylinder for the replaced injector (no. 4) is 1.72 mg / stroke. For 1,2 and 3 it is -0.2 / -0.95 / -0.65. Can I do something to fix this deviation?
@@TheKeenMechanic i see something about a regeneration and "adapting injector minimum deviation quantity" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GBvMHFEe3bc.html .This procedure solves this problem oh this deviation ??
Hi Great video good explanation, I just had this problem on my way home to denmark on the German autobahn. we had it fixed at a proffesional werkstatt it cost me 650 Euro all inkluded wit a new Injector. I hope i have not being ripped off ;-). my carr is a Passat b6 3c2 , i think it is the same engine as you show here. I was curious to se what they fixed. To things i want to ask you: is it whise to replace with a used injector , I think you can not know anything about the condition off the injector , you do all this work and than maybe you soon have troubles again because the Injector has maybe 180000 miles on it. Do you know anything about the life exepectancy off this spare part when tey are new (original VW make).? THX in advance for your answer :-) :-) BTW I have a smal OBD analyser that showed the P0202 code , cilinder 2 in my case. so I was beware off the fault before the german technician came along. :-)
Hi and thanks for your detailed message. Sorry for the late reply, still at work although I will try to answer your good questions as best as I can. It is very sad that these piezo injectors fail suddenly and without any warning you are stuck on the road. This happened to the car owner of the 1.6tdi golf 2009 I recorded the video on. The car lost cyl 3 error P0203. The owner didn't have breakdown recovery and drove 60miles (100km) on 3 cylinders. I replaced the faulty injector with an used injector at £70-75 if I remember correctly. I am not sure how much a local garage will charge for this job but the price of a brand new genuine injector is about £280. You can buy new injector on autodoc.co.uk Ridex brand for £180 but I am not sure what the warranty is for the ridex one. Used injector normally sells for under £100. Refurbished injector is from 109 to £150 but the refurbished injectors have used piezo element and only the metal parts have been cleaned and refurbished. There is a guy who left a link on my video and he is based in the Czech Republic. He sells new piezo elements for 112 euro, but if you change the piezo element then you have to calibrate the injector in a professional shop on the bench. The best advice is to buy new injector or used from a very low mileage car, if you can guarantee the low mileage. I have heard that these injectors last about 150 to 200.000km but I have seen cars with less or more. The problem in most cases is the piezo element and not blockages hence it creates the P0201 to P0204 electrical faults. The labour for this job should not take more than 1hr including all diagnostics, injector coding and everything else. I would never charge the customer more than £50-60 for this job but I am private guy and the garages charge over 70-80 per hour. In my opinion a fair price for this job with labour and new genuine injector should not cost more than €380. Hope this helps
Just to add: this seems to be more common on the 1.6tdi engine although it happens with the 2.0 too. I have a 2.0tdi cr with 140k miles and no issues so far thank god🙏 The used injector that I replaced on this car only lasted 7000 miles and the owner came back again and replaced it with a new one this time. It is very starnge that 1,2 and 4 are still going and only cyl 3 injector failed twice. Very strange indeed🙄
@@TheKeenMechanic Hi, thanks for the very very detailed explanation. My 2010 Golf 6 1.6 TDI 105 is also having P0203. But on detailed mesures, it shows that : Injector 2, capacity CAPA_INJ_MAIN(1) = 0.0000 uF Injector 2, tension V_INJ_MAIN(1) = 0.00 V So it's not clear now between injector number 2 or 3... But the thing is the injector 3 could be in cause as well in my case. So strange indeed.
@@FBAagent Hi How are you measuring the resistance mate? You should be getting 200kohm if the injector is good. Just remove plug and put multimeter on ohm function. Put probe ends on pins as shown. I have another video that I will link here. It is just a short part of the original longer video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dyfGfM2PNRU.html
Thank you, great job. Just a question, in case the injectors resistances are all good, how do you check the connectors? I mean, with ignition on or off, and what's the correct resistance to measure on the connectors/wiring loom? Thanks.
Great question but I am not sure to be honest. I would check for you but the car is not mine and not here so you are best to check a known good wiring with on/off ignition and see for yourself. Let me know if you find out as I am curious myself
It will work without coding but you shoul code them as the coding is more like fine tuning. The codes on the injectors are actually calibrating values. It is up to you but my answer is Yes, it is necessary🔧🔩🤝
It was interesting to note that you tightened the holding bracket to the correct torque, but then cranked a further 180 Degrees. Could we not instead just use a higher torque value? 30:50
@@TheKeenMechanic I saw two testimonials of screw breakage at 8nm. On the other hand it is possible that the well was not cleaned enough and that a film of dirt remained there ... Do you think that it is necessary to tighten to the couple, one cannot tighten with the judgment?
Anything is possible. I have always used 8nm +180degrees and never had issues when using new bolts. If you are afraid just do 7nm and you will be fine. Do whatever you feel comfortable with.
Yes, but only by a professional injector specialist. Every injector needs to be bench tested and calibrated. The piezo element also needs to be replaced by a specialist. Not much can be done at home without special equipment. You have 3 options: New Used Professionally Rerurbished
It happens to 2 litre version too but very rarely compared to the 1.6tdi. I have the 2.0tdi personally at after 9 years and 150k miles no problems so far. Thanks and hope this helps
@@TheKeenMechanic So it is better to buy a 2-liter version. Is there a difference in fuel consumption between the 2-liter version and the 1.6? Thank you
@@abdelhakimhakim1164 Yes. The 2.0 is the better to buy. 2.0 might use a bit more fuel but it depend how fast you drive it of course. I would personally advise you to buy the 2.0 tdi if you can.🤝

Hi and thanks for the Good question. If the problem is electrical, like in my case it will show a fault, but if there is a mechanical issue with the injector, like a small blockage I would say there might not be a fault. The best way to check this is by doing a back leak test. This will show if some of the injectors are blocked and more fuel will flow through the return pipes. Hope this helps
@@TheKeenMechanic Thank you very much. I have exactly the same 1.6 90 hp CAYB engine in the 2010 Skoda Roomster and it sounds like a loud bang. I want to find out what happened because the engineers ask me for huge amounts in case of failure. One last question. When and if I change one or more injectors will I need some adjustment or will the engine work normally?
Hi, if you replace the injectors with new or 2nd hand (used) injectors the engine should work ok even if you dont have the diagnostic software to code them in. It is recommended that you code them but for a short period of time just to check if everything is working it should be fine. It is very hard to get used injectors for a good cheap price as this is a common fault and they are very sought after. I would advise you to do a back leak test first to check for blockage then if ok, look for other issues. You can buy a cheap kit online and try to do it yourself if you are confident. Hope you get it sorted and let me know how you get on👍
Very good to know as this is very common fault and very expensive to fix. Sometimes 4 new injectors and labour can cost nearly as much as the value of the car here in the UK. Where are you based yourself?
@@TheKeenMechanic I'm in Ireland they can be expensive to fix alright. A questions for you is it worth putting a clutch into a 2008 Toyota Corolla with 260000 miles on it?
@@browningmaxus5360 Hi I am in Northern Ireland-world is so small 😉 If you can do the clutch replacement yourself it is worth as you will only pay for the parts and keep the cost down. If the car is well looked after and reliable in any other way I think it is worth. I have seen Toyota taxis at 900 000 miles without any major engine work. Hope this helps you decide
Hi I bought the delphi cable and software on ebay. This was many years ago but I am sure you could find it with some searching on the internet. Try with searching for DELPHI DS150
Hi, the problem is electrical and is in the injector electrical circuit. Unfortunately here in Northern Ireland nobody is able to repair the injector coil as it is probably very time consuming and it is more practicable to replace it with an used or brand new injector. I have been told that it should help if you remove the plastic engine cover to keep the injectors cooler as they fail electrically potentially due to overheating. I replaced injector 3 with an used injector and at the time I removed the engine cover to see if this helps and 1 year later no problems, so may be it is just me being lucky, but the engine is small and not very noisy, so there is no increased noise in the car with the engine cover off in my opinion. Thank you for the great question and interest in my video
In my opinion the 2.0 injectors are better. The 1.6tdi engine seems to have more problems with these injectors. I have a 2.0tdi as well which has 40k miles more and I have never had issues with it. I am sure someone else may say the opposite, but this is just my experience and opinion. Hope this helps
@@TheKeenMechanic i got same problem as yours but only when dpf regeneration is on. In other situations engine runs good. Can you suggest me why i get this error?
@@menel321If I understand corretly your car running on 3 cylinders when is regenerating? Do you get fault and engine management light on dash? Give me a bit more information please. Normally when a vag (vw audi group) car regenerates it changes the fueling to increase the exhaust temperature and the engine will sound different anyway.
@@TheKeenMechanic yes car is running on 3cyl when dpf is regenerating. After regeneration car runs on 4cyl and then i have P0201 circuit malfunction error.
From the fault I can tell that it is cylinder number 1. Check your wiring thouroughly. If the wiring appears good then if you have the tools and skills swap cylinder 1 injector with cylinder 2 injector and see if you get P0202. If you do then the problem is in the injector most likely. Injectors are held in pairs 1 and 2, 3 and 4 with 1 clamp and bolt so just swap 1 and 2.
Great tutorial - just got same fault on mrk 6 golf . P0201 confirmed with multimeter after following your video. just want to check , i can buy a used injector from breakers and it will code to car . 03L130277B
Yes. Make sure you bring your multimeter with you and check the injector at the breakers. I would recommend to buy refurbished or new. The used injector I put didn't last even 5k miles and had to do it again and this time I put a refurbed one and no issues. Yes that code should be fine, just make sure the coding code is clear to read if buying a used one🤝
@@aldo5305 just be very gentle. Should not be hard. Have a look at how I cleaned mine and should be sufficient. These injectors come out easy and are easy to install so 🤞 you will save yourself a fortune🤝
