Hi
This car was brought to me as a non runner...
On a first scan, I noticed that I could not communicate with the DDE (Engine ECU)...
Follow me on this video to find out why was that, and how I fixed it!

This is why I always prefer my favourite independant 'shed' mechanic instead of some commercial garages. 10 minutes to figure out what a full crew garage couldn't do in days. Great job, love these videos.

Great work by lm autos as always . Bring ecus back to life. Had a few jobs done by him. Always come back perfect !

Thanks Nuffz, for watching and for your comment!
@@LMAutoRepairs I’ve got a e90 325i that I believe has the same issue at first we thought it was the voltage regulator so I had a new alternator put in but the it won’t start. Cranked so I also got a new battery but it’s just won’t start. Scanned with snap on and was getting engine ecu fault code so it now stranded at the garage and I don’t want to keep paying for parts that isn’t fixing the problem.
Where abouts are you based and how can I get in touch for the job if not can you help identify my options or recommend garage of ecu/ electronics specialist that will take on job or a solution
@keyonfrancis2722
You can get the ecu out and inspect without much effort, and you will be able to quickly establish if it has been on water...
👍👍👍
Wow, nice work. I have my BMW745 with the same problem!' No communication and after a week in the shop, he gave up and couldn't find why he couldn't communicate with the car. My car starts ,but the airbag, horn, windshield wiper all disabled. I wish you were around here. Thanks for the great video.
AGAIN...Another Great job Louis, the patients you have to resolve a problem and to save this board is inspirational, keep up your great work, top engineer mate...
😊
Thanks!
👍👍👍
Incredible how you are able to bring those ECU back from the dead 😁, just before I started watching this video I looked into a Corsa Crank no start where the pump in the tank runs for too long I hope it’s not the same issue 😬... cheers Luis 👍
Corsa D diesel.... well... you might be lucky... but they are known for flooded ECUs... lol
Thank you for watching and for your comment!
Yet another display of your diagnostic and repair genius, Luis..!
Hi
Thanks Jeff!

This is what called hard work. I like your method of diagnosing and repair. I work just same like you but in middle east. I wish for you good luck.
Thanks, and good luck for you to!
👍👍👍
Nice fix asusaul, thanks for the patience and effort you put into making you videos.
Thanks!

Your knowledge and ability to repair the DDE is very impressive. Thanks for sharing
Hi
Thanks, for watching and for your comment!
😊
As a retired pcb designer and fault tracer I am impressed. I didn't think there were any younger people coming through with there skills anymore. A I said.... impressive !!
😊
Thanks, it is just a shame that right to repair is not something that industries embrace... making schematics etc more easily available...
Would make things way easier...
Thank you for watching and for your comment, really appreciated!
Your patience at repairing stuff that would normally just get replaced is impressive.
Thanks!😊
Thank you for the video. Solved the issue which main dealer couldn’t do. Customer spent loaaaaads of money before and issue was still there. Contacted me and solved by replacing the DDE. Thumbs up and subscribed 👍
😊
That's great!
Thank you for watching and for your comment!
Another drain hole blocked....ecu not water-tight...you did a great job with the pcb, cleaning and repairing it.
I think Ronnie O'Sullivan said the same as you. Luis...He won the match early so he could pick the kids up from school! lol.
Very well done!
🤣🤣🤣
Thanks!
👍👍👍
THIS WAS THE MOST IMPRESSIVE THING i HAVE SEEN IN A LONG TIME! Thank you for sharing this.

You know that u are number 1 right? Thanks again for sharing your incredible work with us. From everything that I've seen from you until now my favourite is that mini cooper that came from another garage specialist for bmw and mini. This perhaps is from the same garage. Anyway Thanks for this 30 non blinking minutes 😁😁😁
😊
Really appreciated your comment!
Thanks!
👍👍👍👍👍
I have exactly the same fault with a 2008 320d I’ve just bought, non runner. Pump running constantly, all sorts of error messages on the dash, crank but no start. No DME communication, was going to look at the ecu connection first but you’ve confirmed what I was thinking. Thank you.
😊
Still, due your due diligence... just to make sure...
👍👍👍
@@LMAutoRepairs well, ecu tray completely dry! No corrosion anywhere but I’m going to open the ecu and have a look just in case
Amazing repair and was great to watch, when you removed the DDE board I would have never imagined something like could be repaired. It's a shame the chap had to spend so much before it got to you though. I'm going to check my car soon to make sure my drain plugs are okay Haha.
Lol
I would check it... 😉
Thanks for watching and for your comment!
Hi Mate, I salute you for your great initiative and patience applied in resolving this issue. You are a STAR. You just diagnosed and explained a replica of my BMW 1 series 118d coupe manual diesel - Crank no Start! This happened over two weeks ago, and yesterday, I had to open the ECU unit and discovered a water log at the bottom, and eventually water had gone into the panel thereby causing it to stop communication. I ordered another ECU from eBay yesterday and it will arrive tomorrow. Though it has to be cloned. But If I'd seen this video before now, I would have taken the chance to do the same. Maybe mine could just possibly need to be cleaned with spirit and allowed to dry. You are just a genius! RESPECT👍
Hi
Yes, an used ecu will need programming...
It might still worth a try on yours... 😉
👍👍👍
Hi great Tech-Man, thanks for your response. Well appreciated. Just like you ascribed, yes, it might have worked out if I'd watched your video and applied the techniques you used in your video...smiles. I really appreciate your expertise vibe. I will be following you on here constantly. You are a great Tech-Man👍

Hi Luis your videos are very informative and good enough I am requesting you to make the video on how to check the ecu board continuity and trace out the track paths and how to check the processor and eeprom etc about their condition and what are the issues caused by the each one when they are defective
Well done ! ! ! Watched with pleasure.

Hey loved the video, was just doing my research and stumbled upon this. Appears to be the exact same issue as a E90 330d I have. Pump staying on, not starting, red cog of death and flooded ECU. However I couldn't bring my ECU back, getting it cloned, hopefully sorts the issue
😊
👍👍👍
Fantastic job!!! as you do always !!!

I had a similar issue on my E46 330xd with the DDE 4.0 (M57 Engine). Water got inside the ECU, i think maybe condensation causes this. No communication with DDE was possible, also the water temperature gauge was at maximum when ignition was turned to on position. It was communicating again after cleaning and treating with hot air, but failed shortly after again. So the easiest solution was to get a working used unit re-programmed. This will cost around 170-250€ in Germany. Greetings from Bavaria and thanks for this helpful video!

It was good diagnosis and repair but you forgot show us IC epram
And everyday I'm waiting for your new video I really like your diagnosis thanks for your good info
Well, in the end the chip was not an eeprom, neither work was necessary on it...
Thank you for watching and for your comment!
Very good work sir ...
Thanks!

Very helpful video. I like it
Thanks!

Ahhh very interesting, I have exact faults, I had same original fault ‘locked steering’ and I have run same diagnostic with resetting and sync of modules but still no dde communication.
I’m going to remove the ecu tomorrow and check for water. Let’s see!!
I have a 320d E91 07.
Amazing video and very informative, you certainly know your stuff.
Thanks!
Hope you find the issue with yours...
👍👍👍
@@LMAutoRepairs yes it was water
Damage to the ecu. Exactly the same as your video!! I’m on the hunt for a used ecu. Now! One of the chips along the bottom has blown in half!!
@@LMAutoRepairs I feel like I need to repay you for your videos! It really helped.

Thank you for the video absolutely amazing work and as Denzel Washington said hard work works
Please do some videos about the security system in BMW. I heard something about resetting the working hours when changing a module in this car, and transferring the ISN " I don't even know what is this" and how to change the VIN in this cars maybe with a cheap way I have seen that you did this with maxisys.
Thank you again for the video
Hi...
I have more to come, and have a actually no runner on the driveway...lol
ISN is like a long security pin, used between the CAS and DME/DDE...
There is dedicated tools, however expensive, to especially work on those systems...
Thank you for watching and for your comment!
Thank you for this video !

Esses BMs já não é o 1º que apanhas com a ECU mergulhada em água. Deve ser problema crítico dessa carroçaria de BM. Os escoadores entopem e a água não escoa. Ainda por cima aí na Inglaterra chove mais do que faz sol por isso é complicado. Essas boards ainda por cima são multilayer e as camadas do meio se um gajo não tiver esquema está praticamente tramado da vida. Gostei muito da tua solução que na verdade é a única mantendo a ECU original do carro. Caso contrário só uma ECU nova e depois é aquela seca de programar VINs e funções específicas do modelo do carro e do carro em particular. Enfim. Uma carga de trabalhos. Fica bem e continuação de bom trabalho. Abraço dos Olivais em Lisboa.
Sim... é um problema comum... não só nos BMs para ser sincero... tenho agora aqui em S Class (W221) que apesar de não ter danificado nada, andava com um aquário de cada lado... 😅
E sim, as multilayer são do diabo... 😳
Obrigado pelo comentário!

Had same issue wish I would've figure it out before I took it to the dealer. They couldn't figure it out with out having to replace every sensor possible before they diagnose a bad DME. Two weeks in the dealer waisted. I decline anymore work. Took me a day to figure it out. Water damage DME.
Sorry to hear that...
At least you found the issue in the end...

I have a 335i 2009 n54, and after I replace my injectors and assemble everything back to code the injectors and to my surprise DME is not connecting to my OBD plug, and full pump runs at all times when ignition is on, this might be my solution, thanks a lot.

Another brilliant video from you luis, always very interesting, just wanted to ask how to correctly remove the black plug connectors from the ecu as I tried to remove one the other day and couldn’t figure it out so I stopped as I don’t want to break anything.
Thanks, Chris.
I use a desoldering vacuum gun to remove the solder from the pins...
Then the hot air if needed... takes time, be patient...
I liked and subbd man, good job
Thanks!

@ 29:59 "and that's all I done" under statement of the year LOL !

Where you located I think I have the same issue with my 1 series but I don’t have any dashboard lights at all seems like a electronic fault also my fuses seemed to be a big moist when I took a fuse out to check . Please could you let me know as I need this issue resolved as soon as possible
nice work,,, perfect in the diagnosing although id change that ecu 100% as it just cant last in that condition ive done quite a few, another good ecu change immo chip and resync would be a better fix all round peace of mind, that said great vid
Still going strong...😊🤞

You sir, are very good at this. I’ve watched a few of your vids, even the other dme vid twice which was over an hr. I have been struggling with my e90 320i 2007. I was wondering if there is a schematic pcb diagram? Even with that I’m not sure I can fix my issue. Thanks for the great content! 👍
Unfortunately I work blind when repairing this type of stuff... I never managed to find internal schematics for modules like this...
You need to try to trace it down... if is a multilayer pcb, then things complicate a bit, depending on what type of damage the ecu has...
Thank you for watching and for your comment!
Have you had an experience with an 2004 BMW 530i that wouldn't start after replacing the battery. When I put the key in the ignition I get the orange key symbol on dash (guessing to show that key is in ignition when door is open) and nothing after that. When I turn the key I don't get any lights at all on the dash and I can't even get the windows to roll up but the radio will turn on and the lights inside. Any suggestions of what to test?
Hi
Which battery are we talking about?
The key battery, or the car battery?
When you say orange key symbol, what symbol is that exactly?
👍👍👍
Great sir great video

Any ideas where the AC compressor relay is located? E87
Had 2005 with exactly same symptoms after customer tried to jump start after battery gone flat also had no comms with DME
But didn’t had the chance to get to the bottom of it as customer decided to take car away and scrap it
