Citroen C4 1.4 not starting. P0201 P0202 P0203 P0204 P0443 open circuits. Fault finding and repair. 

Hi, Great stuff you put out. It would be even better if you could make more detailed video's ie. how you traced wire from coil 1 to finishing adding the temporary relay. Also where do you get the schemstics diagrams from pls.

Dude you are a hero. Its literally pitch dark where i am and your video just saved me.

When money is short and the customer just wants their car to run this repair is just fine and professional. Your solution is definitely not a 'back yard hack'. Your an ace diagnostician Luis. You could get a job in a high end workshop anywhere I reckon.

Best man ever. I took my car to 3 mechanics and they haven't got a solution to the problem. I figured out myself watching your video. Thank you very much man.

You are one of the most clever mechanics on RU-vid. You deserve a good salary for your skills.

Ingenious way to overcome a manufacture weakness. Seriously impressed with the diagnosis & fix 👍🏻

" for citroen , it looks factory fitted " , you made my day bro.

Genius. Your by far the best RU-vid streamer in my opinion. You explain the process in great detail and you always find the fault and always have a fix. Carry on with what your doing I can see your channel grow with subscribers. Nice job👍

Excellent!! I was able to diagnose and fix my wife’s car. Used power supply from fuse 13 through 85 on relay. Out relay on 87 to fuse 10. Back in business!! Thank you so much!

YOUR NO DOUBT THE BEST MECHANIC ON RU-vid.

i really learn a lot by watching your videos thanx for taking the time !

Thank youu so much for this video!!! My car stopped working while driving to another city. Thanks to this video we were able to fix the car easy and fast ! You are a genius ! You have just gained one loyal subscriber for life!!! ❤️

Thank you very much for sharing this video. It seems like you were working on my citroen that has been out of work for almost 3 months, a mechanic managed to turn it on and get it running but after a day or two the problem reappeared . I will ask for a more skilled mechanic to take a look on it based on this video. I will keep you informed. Thank you again

Thanks man, I had the same problem today and I temporarily bypassed that relay with a wire enabling me to get the car to the shop. In case the shop cant fix it I will do it during the weekend. Thanks!

Merci beaucoup, cette vidéo m'a non seulement aider pour la C4 1.4 L de ma mère (DTC P0350 / despite new ignition coil), mais de manière générale, j'ai encore appris des choses par rapport au raccourcis du fusibles, vers son relais. Thanks so much, it will help people who love D.I.Y;

Car with the same problem came to me today Luis,just a 1.6 engine but all the same...............easy fix thanks to you.......

Good new name for the channel - I though I'd just discovered a new car diagnosis channel until I heard your voice!

Absolutely superb job Louis. Keep up the great work and your superb videos. Well done.

Hi mate I've been there done the exactly the same thing on many of occasion people just don't want to spend money we have to do what we have to do sometimes we can only give the customer advice and then it's up to the customer at the end of the day great video mate

Excellent video, I like your workaround the relay fault.

New name but same great content and detail. Keep up the great work.

Lm need to get a box of tripods in stock lol We the people need more detail 😎 great videos great info (just a little bit more detail) and you would have one of the best up and coming channels 👍🏻👍🏻

Hi Buddy The key was your wiring Diagram, and yes it did look like a factory fitted Mod for Citroen, the customer should be really happy with the big saving, just shows what can be done, IF; you know what your doing, another good Video

Great video and great fix also love the new name for the channel

good video mate will be sure to keep tuned in for ur other jobs

Another great fix, they are lucky you could bypass it! It's crazy those modules are sealed with compound so you can't replace the relays, damn you Citroen/PSA! I've had relays fail on a few cars Ford, VW and BMW (sticking DDE relays) at least they were pluggable so could get them running again. Nice to see you've renamed your channel! Big thumbs up!

Sometimes you can only do what the customer is willing to pay. Big Thumbs Up..

You've earned a subscriber sir.

Hey, official dealer of Peugeot, Latvia, did this same thing to mine petrol 407, even looks like they found your solution for my situation 😂, which is the same. But they really fucked up because ignition relay, which btw controls depollution and coils, wasnt really fried, just sticking, so when I drove for like 30kms, original relay started to work simultaneously with the new one, and engine management system crashed immediately. Had to use evacuator. So this works only if that relay it really gone.

hi, nice diagnosis and a simple fix sweet .

Nice fix and the use of a relay

Nice job mate,,,,,,,,,, "Sorted !!!!" I thought I was watching Bodge it and Leggit :-)

Muchas gracias amigo. Tengo el mismo problema de un peugeot 307. Gracias

Thank you very much, you just have helped me ❤

Buenas soy de Uruguay. El pin 86 relay de donde toma señal ? Tengo el mismo problema. Conecte todo pero queda la bomba de combustible siempre prendida cuando le doy contacto antes de arrancar. gracias y muy buen tutorial

Nice. You could also provide power to the additional relay from ignition switch (terminal 15).

Good diagnostic amigo nice video. Tengo. Una. Preguta. Amigo

hi my teacher , nice job, also love the new name for the channel the system prevents fuel vapors in the fuel tank from escaping into the atmosphere; and The most common problem with the purge valve is difficulty starting right after refueling at a gas station: for the first few seconds the engine may run rough and stumble but What is the resistance of the sensor itself typically

I give thumbs up before watching video I know its awesome

Hi. Very good video. Question, if I turn the key to ON and there I measure the voltage in the F10 and - of battery, if the relay is faulty, should there be voltage in the F10? Thank you.

I am from nigeria and this is the problem i am facing with my c4 but i'm gonna try this procedure to see if it will work on mine..

TOP job Sir !

Very clever man. well done

thank you very much very nice and interesting video

Very good explanation and testing procedure could the faulty relay have been caused by the faulty connection you cleaned causing the contacts to over heat just a thought thanks

Hi, I have the exact same car in my workshop with the same faults. (Australia). The relay powers the injectors and the purge valve (reason for codes), and also the ignition coil (transformer coil at bottom of diagram), but also the fuel pump! Lots of loads on the one relay and only 2 fuses! Very poor design. Very easy to fix compared to security issues in later models.

Great fix!

Does any one knows where to find a relay like this to buy please, and could you send a link? Thank you!

The best expert

Great job u r genius

Great job man 👍...

Great fix. My wifes C4 refuse to start after short journeys. Broke down. Changed starter motor, as solenoid power contacts failed/badly worn inside. Will not restart. Clicking at passenger footwell. Any ideas gents ? Elp!

New viewer ,great vids...and info...

that's a good fix it works fine, and like the guy said, it's not worth a lot of money, also the new relay will probably outlast the car. lol

Hi I am very thankful for your video . It's helped me a lot I have the same Probleme in car . If I buy one neu or used BSF does it need to programming ?

Was waiting you would show how you wired and connected the relay. Thanks

If you could show us more details how did you take the part apart and repairs would be better, thanks! Great work anyway!

I have problem on c4 2012 how to get to you to diagnose. It was parked for long time and lost key, managed to do key not from dealer but it won't start. I have been told to change bsm but remains the same, when I short two fuses on top of battery connection it get electric on dash and start but it gives random faults change the connection on top of battery second hand, still the same. Need to jump fuses. Changed preheated relay still no improvement

C3 break lamps can be problem to,I usually do the same thing ,ie the one side that still works becomes the trigger,so minimum draw on the transistor then fuse rally to lamps 7.5 amps so the circuit protected

exellent work mate

nice great find...

Sorted ha ha ha. Another great video. The wiring diagram, is it part of the diag program or a standalone program. Thanks mark

hello master. do you know which relay is from the basement blower in BSM L11-00?

Fabulous work, I just was wondering where you get the ignition switch signal to activate the external relay. Many thanks in advance.

Nice video thanks I have question mr what the name of diagnostic software which you used

LM, I'm a noob working out how to wire this. Could you put power to external relay from fuse 1 then ground that. Then 12v from battery to relay to fuse 10? If not what wire do you tap in to to make relay 2 work?

Nice work 👍.

Good job

Im seated with that and i just cannot see how you connected your relay there

How many diagnostic computer you using which one is the best

Hello, I have a problem with my Citroen Evasion 2002 auto. When I try to start it, it cranks but the engine does not start. I found out that there's a problem with the ECU (TEXTON). A spare part for this is hard to find in Malaysia, so is there a way for me to bypass two electronic components (relay)? Or do you know of any other alternatives that I can try? Thank you very much

What is the size of the relay so I can get sample

Hi i did this worked great but got p1351 manufacturer control and wont rev over 2200rpm any help be great

Had code P1694, but also forgot to mention that after ot started after lots of attempts the prelast time, i had a "low oil level" warning and added it almost 1,5L of oil...now guessing if it's possible that the oil level sensor prevent engine from starting to not damage it?!...

Good work, can I ask how you connected to the fuse.

Hi, Thanks to you tutorial I have been identify the fault of my C4 1.4. I have connected the line directly from the batery, and runs. But I can't see how do you have install the external relay. Can you show how to do it? Thank you very much! 👏👏👏

I have the codes p0201, p0202, p0203, p0264, p0204, p0205, p0256, p0354, p1341. on peugeot 407 3.0 gasoline. bsm L02-00. The gasoline pump is activated. but the engine won't start. Do you think that by doing this I can solve it? In the official peugeot service. They couldn't fix it.

Nice, does citroen wiring diagrams came with lexia?

Molto grazie 💪

Rl40 citroen bsm.do it need Coding to bsi citroen dispatch 2.0hdi 2011

what if i conect direct to the batery with 12 volts external switch?

Great video, I have the same problem with a Peugeot with a similar box. But I'm afraid that there is some kind of security risk in that connection. If the fuel line breaks, the control of that relay 2 is probably supposed to stop the fuel pump.

Hi, Where to source dealer level diagnostic kit for Renault? Is clip the only interface that can be used as vcm? Thanks

i have apparentlly the same problem with peougeot 307 which misfiring the cylinder 4 can i perform the same steps what do you think

Hello, I live in Brazil and I have the same problem with BSM, the scanner gives the same errors as your video, I would like the electrical scheme you did if you could help me to get my car back to work. Congrats on your video.

I was wondering if the earth could not have been picked up off the bsi so you would then be replacing it like for like? The relay you added would be shut down by relay 1 but the bsi may have other protocols in which relay 2 would need to be shut down first. Long time since i have looked in a bsi by the way lol. Well done on another great video.

what scanner you recomend for a 308 peugeot car

Hey, I got the same problem in my car. I was wondering if you could send me a sketch diagram just for me to look if I´m picking the right wires. Or is it possible to just power the fuse without doing anything else? Could you do that please? Thank you.

Great video as usual! U are the man

Hi sir,can you please explain to me me the connection to that external relay you made. Can only see the positive wire from the positive going to the positive terminal and to the number 10 fuse. Can you please breakdown the connection from the relay to the Bsm

Where abouts are you? I need someone who knows what they are doing to look at my car. I've got P2970 error. I did have a heap of errors p0192, p0500, u1000, u1118, u0122, u0103 and p0483. The garage doesn't know the cause and suggested to try replacing parts to see if they go away and I'm not convinced.

Hello , my headlights flickering at 2000 rpm. I cleaned the battery terminals. My car has 150000 km. Alternator problems?

My Peugeot partner 1,6 hdi 2009 is doing this it starts OK then it won't start then a few tries later it will. Any ideas? Please help

Hi, I GOT problem with pneumatic suspension ecu of citroen c4 grand picasso 2008. I have diagnosed myself there are three code's came which are 2 of them related from pneumatic suspension i guess, basically both codes states " U1324 fault: absence of communication with the pneumatic suspension ecu. No single". I got 4 of these codes P1351, C155D, U1324, U1219. I hope you give me help out

Good! Work diagbox on windows xp good ?

Those relays in BSM are fixed in some glue or some electrically insulating paste and are imposible to remove them!

I wish you lived in my country. My sister has a C3 1.4 petrol and it tries to start, sometimes starts but failing. And has a lot of codes.
