Vauxhall/Opel Corsa D Z14XEP no start. No ECM communications. Fault finding and repair. 

Why do people even give a thumbs down. You know how hard it is repair and record at the same time? Good Job, Thank you for showing everyone your hard work and sharing your knowledge!!.

Really good detailed and inspirational video. Who works on this matter can understand how much toil is behind.

12:09 no engine light on, so you can tell with no tools that the ECU it's not alive. Great job, not many would have touched this car after seeing that mess.Lucky owner.

I do not understand the language well But I understand from your wonderful way of working Real, you are one of the best and most useful channels on RU-vid👍👍👍

Great video. 10/10 for sticking with it. ( I would have sat down and cried if someone had brought a absolete mess like that to me ). I am going to add you to my subcription list. 150% super impressed.

Well done mate that was amazing, the fact they brought the car to you in that state tells you someone said "i know a guy who can fix this" Good work and kudos for going the extra mile :)

Well done Luise. Am glad you haven't gave up. Excellent video start to finish.

You make a very good point when you ask people to leave the car the same way as you find it.

I've worked on cars before where numerous people have butchered the job earlier. Makes it a lot harder to fix. You never get the full story. Love your videos. Just subscribed to your channel.

"Hello everybody, welcome to another problem solved" . Congratulations! Thanks for share your acknowledge.

Nice diagnosis & repair. Gotta love it when you get handed a vehicle that they've torn to pieces!!

Hi there, most of these hybrid ecus found on GM opel/vauxaull and Fiat hybrids ecus they all suffer from misfiring,it starts by 1 cyl or goes to 3 cylinder misfiring, these are faults that i have dealt with on these hybrid ecus. need to replace them or if u have proper soldering equip u can repair if its desoldered wire due to vibration. But hats off for not quitting the job on this vehicle and the repairs

i subscribed after first minute. dude, i would gladly give you my money to repair my car. top notch. i wish everybody would work like you. thanks for all the videos you put out here for us.

ECU's which are mounted on the engine or realy close to the enginge are known to get broken. Mostly if the engine get overheated. I see it a lot on Opel and Fiat Punto's. What i do after finish, i mount the ecu on the wall of the car (don't know how to call it in English) and make a new ground point on the chassis. If i got a car with this kind of issue i also test the ECU on the bench. I made a testing cable with OBD and power supply so i can connect it to my diagnose equipment. sometimes it is enough to read flash and eeprom so i can clone the ecu to a new/second hand one. And yes.. the one before you made a total mess of it! Basterds! Once again a great video Luis!

Very good repair,enjoyed the video,I hope the person got you to repair the fault,if he did not,crazy.thanks,made me smile,you are a crazy man.

It's probably been into Vauxhall first. My wife's friend has a corsa D. The starter motor was intermittent. Vauxhall put 3 starter motors on it in 6 months. Then, they suggested a new ignition switch and full loom. I told her she should have come to me first. It turned out to be the battery feed to the alternator that spliced to starter motor. Crap design on Vauxhall's part.

Looks like engine is out of timing! Last week I had the same no communcation with an Astra H Z14XEP coming from other workshop. Finally the car started after finding one blown fuse and one missing. Afterthat, ECU ground for MAF/IAT was missing and ECU was replaced. Really enjoyed the video as I did the same diagnostic steps and programming procedures! :)

you really did take time and effort to do a good repair job . very good work indeed.

I don't know much about this Vauxhall Corsa, but when my 1967 Ford Anglia used to misfiring, it was the points needed cleaning inside the distributor cap and gap set correctly using a feeler gauge, may be that's what you may be you also need to do, and clean the rotor and check all 4 spark plugs, oh and often the condenser in the distributor can go weak and give a weak spark, I hope this helps. Also while at it, lubricate the governor weights underneath the contact plate which controls your ignition advance, and make sure there are no leaks on the vacuum advance capsule. So much for modern cars!

Great video really like this type no com will be waiting for the next video the fix that the customer complained about much appreciated keep up the good work I am sure many people will learn and gain knowledge thanks

Once again great job Luis. It's a nightmare when someone else has been messing around with the car. Thanks for sharing! 👍

Another first class job. I'd have given up and sent it back, but you always keep going. Probably the best diagnostic technician on YT.

The best Corsa tuts

Looks like chain has stretched, Causing the misfire. Good job as always

I watched this.Good fix. Have you not come across solder sleeves that will join a broken conductor, you can use a heat gun [no naked flame] and it also waterproof seals both ends in one process. Heat seal inline crimps are another alternative. Much easier and relaible. Insulated too. No need for heat shrink sleeves

Hey you always get the nice jobs already started by someone else 😊😋... top job mate and nice to see the tech 2 working 👍👍👍

Wow, people that don't know what they are doing can make such a mess. That repair will make a big hole in the wallet. For you L-M repair I'll take my hat of, great video as usual.

I’m so impressed by your personal dedication to your work. You’re a genuine genius and it’s so wonderful to see the talented and knowledge that you have. My daughter has a 2009 Corsa 1 liter petrol which cut out completely while she was driving to Dublin. I took the car to the local Opel agent who had it for a week, couldn’t fix it because they couldn’t get the cars ecu to “talk” to their equipment. They said that the ecu will need to be replaced at a cost of approximately €500+vat + labour. They charged me €370 for the time which they had spent on the car (achieving nothing) and told me that even with a new ecu there would be additional costs to rectify whatever the problem was that caused the engine to stop. I have just spoken to a local mechanic from Poland, who said that he will source a second hand ecu, reprogram it and should be able to fix the issue for around €250 all in! There is no doubt that “continental” mechanics are prepared to go the extra mile for their customers. Thank you for your posting and great watching and listening to a true expert at work!

Well done sir Luis. Some people shouldn't be aloud to open a bonnet. I have 1 of these ecus if you come across this again

your a genius pal keep doing these videos your teaching alot thanks lm autos

Superb job as always Louis.well done sir.

Great job sorting out some one else’s @@ up... I have this engine in a 1.2 maybe have a massive vacuum leak check the evap valve located on the back of the inlet manifold and also the the four throttle body bolts are tight as they work loose a cure for this is to put spring washers on. Or the MAP sensor is kaput. I also bet it needs a service filters spark plugs. 👍🏻

Tus videos son excelentes, eres un genio. Haces el trabajo como debe ser ..por eso te sigo. Saludos desde la bella isla de aruba.

wow nice job fixing someone bad mess.thanks

you are a genius. thanks for sharing with us.

Good work ALWAYS PROFESSIONAL

Nice and professional job.. keep doing videos!

I very appreciate your job. Thanks!

Thank you very much!!! You have solved my problem!!!! Thank you!!!

Great job as always, super video...

Great video and great job done 👍👍👍👍

Good job luis, thanks for this Video.

Very very very good job! Excellent!!

Ones again you sr are the best rui from portugal

Dobra robota, super 👌

In opels or vauxhalls the "F" means no communications with engine ecu. If radio screen would bigger, the range would be saying F/F. Sometimes Ecu protects itself from any shorts. Like brake lamp shorts, any cable shorts. So it turns off the communications. The automatic transmissions has same "F" issue but yours says there is no problem with transmission.

Thank you sow Match for the information

These Vehicles seem susceptible to corruption of either the BCM / ECU due to a weak battery. The ground for the ECU is another weak area. Thanks for sharing the video, brilliant as always.

Great video as always

Well done mate!

In my entire life I have never had a new car, I have only had second hand cars. When going to see a car if I see that the wiring has been messed with I just walk away. Even though I'm quite good with electrical and electronic systems I do not have the time to unravel someone else's feck-ups!

Excellent video, cheers.

watched this long but worth while thankyou

I like your work.

Thank you very much brother

Wow thank you soo much for this video, I have actually learnt a lot...My car had a similar problem, when I did a diagnosis test, I got the following code: B1000-36 ECU EEPROM Error, so I am not certain if I should also replace the ECU completely or not... Sandile all the way from South Africa

Very interesting keep up the good work

Thank you so much for this video

Awesome/Brilliant video and info really enjoyable to watch and learn with the approach you took and ur thought process to solve all that mess they created who ever worked on the car.thanks and cheeeeeeers

Thanks mate! great tutorial

Great video thank you

08:55 I type as I see the video. BCM is gateway. IPC takes ECM data through BCM. So the fault code makes sense. ECM is not present on the bus.

Useful video 👍

Hi may i know what cable connector you use to read opel astra ecu delco hsfi in bench using a carprog? Is it the A10 cable?

thanks very much! its lot of information

Great video sir👌👌. Wish i could ship my problematic astra to you 😃...🤦‍♂️

Tanks voor het video's

Thanks a most useful set of symptoms and. Diagnostics. Why was the maxisys used first then later the second unit showed ,was it more info than maxisys??

very good sir

Watch all you videos never see a bad one yet. Great patience and knowledge what you don't know you find out. Can you recommend a good scanner for vauxhall Astra J. D.I.Y Thanks

I have to say u know ur shit u the master of mechanics i highly respect u ,HIGH FIVE

I had the same issue, changed the ecu because the old one was dead and not readable and now i get the code p1614 and the car doesn’t crank at all and the check light still blinking also after programming, i would mention that when programming the immobilizer function , it has no response at all even if i click this times and times

In this case you have 5v reference or not?? Great job like always, amigo!

Thank you for this amazing video. I seem to have a problem my ecu light comes on with ignition. Yet no immobilizer light or even a flashing one. Any help would be greatly appreciated.

Do you know where location of the bcm is on a vauxhall astra h sxi 1.6 2007

16:07 use a test lamp, forget that multimeter. I burned myself once on exact same test.

Those ECM connector are so easy to unplug. Just press the safety clip and then lift the lever to allow the rail to slide.

Wow! I just started the video.... but what a MESS! ¡Coño! That would anger me... and that's extra. I must put it back together to THEN fix it.... 😣😝 OK continuing to watch.... lol 😅😊

Great work matey, quick question how do you find the uni-t scope? I was thinking of getting myself a handheld digital scope.

Great job as always, where did you buy your Tech 2 MDI from ?

Hello LM Auto Repairs. You make very nice videos! I have a question regarding my 2004 Opel Zafira 1.8 petrol. I have had the car in almost one year now. The car has gone about 208.000 km and i have only driven it for about a 1.000 km. I have changed engine oil and oil filter once. The car has never really run perfectly since I got the car. I have always had the impression that it runs to lean, and have always had bad fuel economy. From the beginning it had problems accelerating out from turns in third gear and almost stalled. After it got warmer it got better but the symptom was always there. Over time the car started loosing more power. While driving on the highway it struggled to keep a steady speed and started shaking around 100 km/h. After the first shaking the first codes appeared. P0170 - fuel trim bank and P0303 - cylinder 3 misfire detected. Sadly i kept driving the car until it got worse and then got codes P0301 and P0304. As a side note it has always had code P1530 - ac cut off relay, but I did not think it had anything to do with the engine performance. I suspected it was due to a bad MAF sensor so i looked up the part at autodoc website, and after typing in my cars registration number as a search method I bought the second cheapest MAF sensor which was from "Johns Autoteile GmbH & Co. KG". Before changing the MAF sensor the car was running very poorly and i suspected it was now in "limp mode" since i could not rev it above 2-3.000 rpm and only drive it very slow. But after changing the new MAF sensor I have started having trouble starting the car and have only been able to start it once with very poor idle and limited revs. before shutting down. The car cranks and will almost start but fails every time now. I have videos of it here: ru-vid.com/group/PLYUcU-L47l0AU_CSsXgR3RhFO4kZqES2z While fiddling with the car a lot I have noticed that some bolts have been missing and some hoses where not connected probably to the throttle body. It is like the previous owner have tried finding the error before me and did a sluggish job putting it back together. The battery is new and I do have spark. I can hear the fuel pump running and have changed the fuel filter. There is also fuel pressure on the fuel rail since fuel squirts out when pressing the schrader valve on the fuel line. I have cleaned and changed the throttle body to a new second hand one. I have also cleaned the little blow back hole in the throttle body. I can not seem to find any air leaks. Next to the air filter there is what i believe is a solenoid valve for the fuel tank? I have tried taking it of and can not blow air trough it in either direction. I am not sure if this is good or bad. I have not tried changing the cam- or crankshaft sensor yet. I have also checked that the ECU has ground connection. In a attempt to restart the ECU I have cut of the battery from the car and deleted all the codes. The only code i get now is P1530 - ac cut off relay. Do I need to reprogram the ECU for the newly installed MAF sensor in order to get the car to start again? Best regards Nikolo from Denmark.

Great video, can I ask what tool you used for the soldering ?

Winners never quit! Well done as always Luis. I have a few questions please... You programmed the key first and thereafter the VIN. If you didn't program the VIN would the car still still be ok with an unmatched VIN? If the ECU was not already reset, what would the procedure have been? Can you share the name of the eBay seller, I really like the detailed description of the ECU they supplied. Thx for sharing :-)

I have a Corsa C 2005 petrol ,car will start with the throttle body disconnected , when I reconnect it it will not start and just clicks rapidly ,changed out the accelerator peddle but still the same , also not able to communicate via a OBD port ? any help would be great thank you great watching you working !

Boss, can you please tell me for Vauxhall insignia 2009 Which Version of OP COM software should I use, if I want to make a Spare car key and to Program a new fuse box with the car. In eBay Version 1.99, version 1.39, version 1.59 available. I was able to download few version from internet too 2012, 2014 and 2010 China clone version.

Lolol that's had some 'expert' technician working on it ! What a mess 😭

Hi I have a no start issue with flashing immobiliser light on corsa d.with opcom I got these codes wrong transponder key and wrong bcm environment.also I have no coms with the ipc or sdm.i checked each plug and I am getting power so my question is are the ipc and sdm ran back to the bcm and the bcm is causing opcom to not have çoms with ipc and sdm

Exelent

Hi and firstly thanks alot for the videos. I really enjoy the videos and learning about car electronics but the problem I have is whoever I phone in the ecu repair world dont want to give any information out to the general public, what I want to learn how to do is read ecu chips off the car, im sure ive seen you remove chips from ecu and put them on a piece of equipment and read the information from the chip, so my question is what is the name of the chip reading equipment and where would I find it to buy? Thanks very much and I would really appreciate your knowledge. Cheers Andy

13:20 sometimes is better to send the f car back and tell the owner to tow it to the Butcher to make it back as it was. And maybe bring it back, maybe.

Good job! How can i extract that pin? Can i do it whit Delphi? Thanks again for the info

hi, why map sensor stay to 101 kpa, i have a problem with same corsa but z12xep and too rich at idle

Good

i got the same issu wit a opel tigra b 2007 z14xep the ecu is repaired when i disconnect the abs modulle the engine runs for 2 secons the tempory fix is disconnect the battery and short the - and + from the car and the car starts and running fine tempory i m now waiting for a new abs pump

well done ide of walked away from that one can of worms.

I got an F on mine and all I can think is F to pay respects and buy new one :P

Dammit This was good

I wouldn't have taken the job on mate I hope you get paid extra for what you have done

Where about in the country do you work from, I have a couple of cars and could use the services of someone like yourself.

Hi ! If i have an ecu from scrap yard can i program into my car without donor car carpass, i have only my car carpass.
