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!

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
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!

Great job. I have repaired them same as you. Going having a go at a 2009 skoda octivaia tomorrow. Not many repair things like us these days.

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.

Superb video Subscribed!
I have a e87 120d 2007 with similar issue. Car ignites but when I try to start the car I get no response, can hear the fuel pump running just like in the video but the car doesn't turn on. There's time where after 5 or 6 times of trying, the car turns on and works perfectly fine, and then there's times where the car doesn't respond at all for hours. I have replaced new battery but the issue still persists. Do you think it is an electrical issue, any faulty fuses or sensors or do you think it is the ECU?
Please any help would be massively appreciated.
Scan the car to start with..
Otherwise it is pure guess work...
👍👍👍
what about the glow plugs ???? the owner will need a new dpf if you dont get glow plugs working Keeps you in work i surppose lol
any idea why the fuel pump was continueasly running ?
Because the ecu was not "telling" it to stop...
Thank you for watching!
It takes a *SHARP* --engine.eel-- (actually lots of them) to put the ECU inside a plastic bucket with no proper drain hole at the bottom; damn, they think of the neatest tricks, we be fooked!
There is actually a drain... unfortunately not up to the job... and blocks easily...
Thank you for watching and for your comment!
All BMW drain holes seem to block very easily and require plenty of regular clearing out. There are quite a few. I've never had problems with any other make of car I have owned but loads of drain probs on BMW 760!!! Gotta keep on top of the issue. 👍
Hello there my friends one series has identical problems if it is the ecu can we buy a new ecu if so what do we have to do ? Or could we send to you for a charge ?thanks dan
A replacement ecu will need programming and coding...
Unless you clone it... that, depends on what ecu you have...
👍👍👍
How much would u charge if we was to send the ecu over to you ?
I’ve already opened the box, but there's no trace of water, and I opened the EKU but it's all okay. I dont know whats the problem. The car cranks but not start.
Help me please??
Have you scanned the car?
Thank you for watching!
@@LMAutoRepairs Yes, all its ok but DDE don t read it. Just like ecu he's not even on.
So, check powers and grounds... etc...
That's where you should have started...
@@LMAutoRepairs i cheek the battery and i dont have sufficiently the power with the little red cable who come to the box red. Everywhere i have 12.40 V but there i have 3.51 it is possible that this is the cause or its normal.
You know whats the reason why i dont have contact with the DDE. All is conectet but the computer not read it??
I have the same errors. I've been suffering for half a year now. The car won't start. I checked all the wires, all the contacts and they are perfect. 😒
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...
👍👍👍
Excellent video! I enjoyed this one very much! Not many people will go through what you did to fix a module. Thanks for sharing bud
Thanks Mario!

usually would have swapped the board out
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!
I have a similar problem. Can you fix this for me?
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

you would think engineers would put these modules relays fuses in a different area in the car !! like wtf ! "ok guys lets get together i have a great idea for the dme location lets put it in the hood area where heat and water can make way into these sensitive electronics " great idea guys !! lets do it ! lmaooo that was a joke

Your knowledge and ability to repair the DDE is very impressive. Thanks for sharing
Hi
Thanks, for watching and for your comment!

Hi I live your videos they are very helpful! I am having the same issue and codes... I cleaned up the ECU with isopropryl and tried to start but still have the same codes and the pump staying on... Do you think I need a new ECU?
Possibly...
Or you can still check soldering etc... untill you find the problem...
👍👍👍
Good save but I would not trust it in long term. PCB is damaged, pads around processor too, just a matter of time until its no starter again. Owner should source ECU, EWS and key while it runs.
This repair was done 5 or 6 months ago... still going...
Still, should look for another ecu... not the whole set... after all, the ecu is the only problem...😉

* Please help me !!! *
I currently have a 2008 bmw 1 series 120d E82 on 130k...
Recently the car has been temperamental on start up when sometimes, after pressing the on/off button and the ignition coming on with the dash lights coming up... when pressing the button again to turn the engine on, the car just makes a "click" sound and wouldn't turn over... after a few trys pushing the on/off button, the engine would come on....
One day after driving the car, I turned the car off and got out as usual... when I got back in and inserted the key, there was nothing, nothing on the dash and no ignition lights at all.. like the car was completely dead or not recognising the key?..
But the keyfob works fine...
locks and unlocks, boot open button works, windows go up and down normally (Not slow from a low battery) parking lights, hazards, and interior lights all work.. but I'm worried that the battery will now run flat from the car not being turned on for days, not allowing me to plug a reader in due to having no battery and the keyfob not turning the ignition on...
The car recently had it's timing chain replaced anf injectors re-seated. I have also had the car scanned no longer than 4 weeks ago which brought up faults codes for the CAS system such as..
• A125 - Incorrect signal from E/M
• A0C1 - Output, terminal 50
• A0B5 - Fault, road speed signal
• A0B3 - Starter motor, terminal 50
• A0AF - Processor
• A11E - ELV fault
• A0AA - Control unit fault
• A0B2 - Supply, terminal 30E/30L
I've been so puzzled and trying to figure out what to replace first...
Here are my options so far from researching forums in Google and watching various UA-cam videos.....
• Check ignition and other fuses under dash
• Replace Battery and have coded in
• Replace Battery terminal
• Replace starter motor
• Maybe look at replacing the Alternator..?
• Replace and have coded in a whole ECU kit including modules, keyfob and keyfob reader
Hi
That sounds like a bad terminal somewhere... check the terminal relays...
Check ground points, a bad ground can cause similar problems...
Check connections, plugs, etc..
👍👍👍
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!
👍👍👍👍👍
Most BMW same issue ECU become faulty because of water
Indeed!
👍👍👍
Impressive diagnosis of board and repair. Not so confident about how long it will last though when car goes over bumps and gets smashed around. Not taking away from anything you have done as impressive but that DDE module should really be junked.
This is my theory...
If he can't take anothe year out of that DDE, is a year he saves...
This repair was done about 5/6 months ago... and still going...🤞
I might have been lucky... have repaired a few of water damaged ECUs... so far, so good... I know will be the day were one will not last a week... lol😋
Still, if I was not confident with the repair, I would advise 100% replace the module...

Hi pal just seen some of ur vids thats some in depth stuff you do! Wondering if you could help with my situation. I have a N57 E92 330d and I accidentally shorted out something by sticking a screwdriver on the starter motor. I touched the main starter wire to the ground and now i’m getting ‘no ecu detected’ when i plug in obd reader. Its got power and lights up and cranks over too but no start. I have tried the fuses but I think they’re ok. Would you know exactly what fuse it might be that i should check or have I blown the ecu? If so…where abouts are you based? Thanks
Think the fuses are OK, is not enough...
Go though all the fuses, visually check everything... that's where I would start...
Thank you for watching!
@@LMAutoRepairs got the rear power distribution box out now and checking that. The one in the glove box I used a circuit tester on every fuse to check and both terminals for each fuse lit up. Didnt do a visual check though as I thought that might have done it. Would it be possible to blow the ecu from the starter wire though as I would have thought it’ll blow a fuse first?
There is fuses in the engine bay... where the ecu lives... check those as well...
@@LMAutoRepairs yup the fuse module relay with 4 fuses in there checked them. Unplugged the relays in there and plugged them back in. Stuff stopped working and started working again when I did. Power seems to be getting through
You might need to check the powers and grounds at the ecu... if all OK, CAN lines...
Oh man :( im anxious.. i have BMW e85 .. had little corrosion on one of two pins inside the socket of the airbag comunication module. But it wont comunicate still :/ IDK do you think its due coroded wire? or its not possible. Thank you sir, hope you read it.
It is possible...
Just measure the wiring etc...

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!

I do this as a part time, and usually take jobs this way...
What is the issue?
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?
👍👍👍
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 !!

I have had the same problem no communication with DDE so i had replaced the ECU with the same part number and programmed in but still same issue, car cranks wont start but no communication with DDE

You can easily restore that leg. Done many times without issues. But only if you have microscope.

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👍

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.
@@samb59
Glad you found the problem!
I’m not sure how I would contact you to take a look at my ECU problems, do you have a website?
This is a part time only...
Sorry...
@@LMAutoRepairs is there any chance you could look at my car in your part time? I can wait a while until you have time?
Hello mate I love your videos they are very helpful. I have had water ingress on my ecu, same as in this video. It clears up well but one of the capacitors had gone, is this something you could fix? If so how do I get in contact to organise?
I don't do that kind of service...
I like to test my repairs...😋
👍👍👍
@@LMAutoRepairs okay mate no problem thank you anyway
Hi I am having the same issue... how do you know one of the capacitors aren't working? Thanks
You can first check for a short...
Then you can charge it and see how quickly it gets discharged...
There tools to check capacitors as well... which will give you more accurate results...
👍👍👍
This is an amazing video and excellent repair. I'll bet your day job is a brain surgeon this is just fun for you.Thanks for sharing.
Good theory... lol

Ben quoi BMW 318i e46 de gasoil
Great job
I recently bought a slightly accident damaged BMW 120d E87 2007 same model like the one you fixed. I replaced BST terminal after its fuse blew during the accident and now its just cranking and not running, engine management light not showing on the dashboard, i dont hear a fuel tank pump running when on, checked all fuses not even 1 burnt.
What next, could it be the same problem as tht one?
It is a 5 minute check, to pull the ecu out... it might worth to check...
👍👍👍
@@LMAutoRepairs ok thnx a lot im gonna pull it out and check wl let you know
Thanks a lot for this video, you the man.
Only to find out that the ECU been removed, if it wasnt for this video i would be busy struggling to make this car start.
So if i buy a new ECU is there need for me to programme it or?
@@morganmujokoro9635
Yes... programming will be required...
Hy guys
I dont have an ECU part number for my BMW 120d manual E87, i dont know what to do now since im getting differents ECUs with the same sockets but im told the mechanism is different.
Help!!!
Fantastic, on a different level !
Thanks! 😊
For watching and for your comment!
I guarantee the drains at the bottom edge of the front windscreem inside the engine bay were blocked

Thanks Jeff!

Hi mate! Awesome video, I have a e90 m47 320D with the similar issue, no comunication with the DDE, but the car is crank and Start, but dont have power I think is from the turbo. In some moments, the fault is resolt and the DDE have comunicated, and the power return. ISTA dont read the Ecu, and the RPM dont move. Is this problem similar with the problem of these video? Thanks!!
Could well be...
It might worth to get to the ecu and inspect it...
👍👍👍
@@LMAutoRepairs I make a visual inspect from the ECU, and no see nothing wrong. No humidity, or corrosion, or another visual problems. I desconect, and reconect and Work, but for a few Days
Have you actually pulled the ecu out of the box?
@@LMAutoRepairs Not, But I can.
I would, just to make sure...
If the ecu is not the sealed type a few torx screws and you can peek inside just to make sure...☺️
Fogo Luís, onde é q aprendeste a reparar assim centralinas? Eu nunca na vida conseguia seguir esse circuito para ver onde tinha continuidade e onde não tinha.
Tiveste q tirar todos os transistores para testar?
LoL
Só alguns...
Com paciência tudo é possível...😉
Obrigado!

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.

Hi my 2007 BMW 520d was parked battery drained and run out of diesel I put about 15 litres of fuel and used to jump Leeds from another car to charge the battery but it still wouldn't start it still cranks but won't start can you please help me.
Scan the car and go from there....
It might just needs priming though...
Thank you for watching!
@@LMAutoRepairs I did prim it with ISTA D
@@LMAutoRepairs on ISTA D the only fault codes I get DDE glow plug cylinder 1 2 3 4

Check live data... something is missing...
Don't scan just the engine, check the CAS... low battery is know to do sync damage....
@@LMAutoRepairs Ok thanks I will try later. Regards
