Another great video for all auto technicians ... where electric meets with electronic ... don't you have any cases not with happy ending ... you should have some , but its natural that you release the ones that are succesfully repaired , thanks for sharing ,
for chips like this you can use chip quick or higher leaded solder to dilute the solder, the chip will flow with alot less heat, rather than wicking it off add more lead! great video though, love them as always, thanks for sharing! EDIT: forgot to add, wick old mixed solder after and apply new
Great work you've done there. I would recommend you were an antistatic wrist strap while working with sensitive electronics. Also please remove the plastic protective sheet from your beautiful UNI-T multimeter, so it will be easier to be read by the camera. Again, thanks and great work!
Uh huh...the protective plastic.... I can't remove it... will destroy my multimeter... you are not the first one saying that though ...😋 I need is to work better the angles... Really appreciate your comment! Thank you for watching!
You really fortunate down there in the UK. Here we not permitted to do such work on residential properties. Jealous neighbours complain and the council issues us with a notice to stop trading from home.

Hi, Forgive me don't know your name, arrived here watching random Mercedes videos, I recently purchased a late w212 250cdi, I intend to maintain it myself and gain as much knowledge possible (6 vehicles now all maintained by myself) , I'm hooked!, watched the video all the way to the end and was mesmerised, sure to say words cannot really express what a great job you're doing and your level of resilience, look forward to watching the rest.
Another great video. I have in the past used part of a split pin to replace a broken pin in a plug as the correct item was not available to me at the time. Keep up the good work.
One simple technique is to use the "spare" pins! Pretty much all ecu's, have spare pins who have not been used at the factory. So jumping to them and exchange the wire placement on the plug. Can save the day, with a little bit less effort and less soldering. ;-) With this said just make sure the "spare" is not broken or corroded as the one causing the issue. This basic technique saved me a few times! Particularly now that my eyes are not as sharp as they used to be. It's a very welcomed detail. My 2 cents. Cheers
Great repair. Very few people would attempt to repair that even fewer would manage to. Out of curiosity what do you think caused the corrosion on the board. Was it water ingress or part failure or something else maybe
I have a similar problem with p0100. Changed maf, flaps deleted, egr deleted, vacuum actators replaced, turbo etc. I can delete the error but in reappers. Any suggestion?
There is only a few things... or the ecu is at fault, there is a wiring problem or you need it remaped... due to all the stuff you have blankedp/removed... that might be affecting the air flow, and triggers the fault... Hope it makes sense... Thank you for watching and for your comment!
Hard work I really enjoyed video I have similar problem for m. Benz Vito 646 p2526 which giving me headaches. Turbo is not kicking in. Its in limp mode
I think those chips are pretty resilient? But before you use wick you could also add leaded solder which would lower the melting temperature and mean less hot air time :-)
LM Auto Repairs thank you, watching your videos has got me interested in cars again. I used to be pretty good with cars when I was younger but I lost interest when they become so computerized. I'm no mechanic but your videos have really sparked my interest in cars again :-)
Hi great video v detailed ! Any chance you could look at my Ecu ?? I’m in Scotland and am struggling to find someone with your technical ability have more or less the same symptoms for the sprinter as this merc is there any other way to contact you ??
Hi :-) Have you got a pinout for this 30344 chip? you can buy new ones, no problem, but no PDF is available :-( as always, great work. greetings from PL ;-)
hi LM after watching your videos, i decided to try ecm repair myself. when searching for mosfets, how do i use the number on the mosfet? when i google the number, nothing comes up. is there some kind of cross reference?
There is some helpful SMD components list in PDF format... actually, there is a few... Google... Also, with the numbers on the components, look for their datasheets... 👍👍👍
I done it on some videos... repairing ecus... but never a dedicated video for it... Unless I have a look, can't even remember now on which videos I have done it...🙄
Okay, I have watched the whole video I didnt realize how did you know at 28:10 that this chip may be the problem and more important - how did you know which pins to measure with the multimeter? Great video by the way!
Hello I have a Vito w638 2.2 cdi,and my curent Ecu doesn’t read my mas air flow meter,no power,and black smoke,can i have a hardware problem on my ecu? I tried everithing else but no result Thank you good work
Hi Not sure what have you tried... But, I would start by checking wiring, measurements at the ecu plug, you can inject a signal on the signal wire and see on live data what the ecu reads... if you have a reading, would probably mean there is nothing wrong with the ecu... you might just have a bad air flow meter... 👍👍👍
@@LMAutoRepairs i have tried a diferent ecu,not the same code,but i could start the engine,and have a MAF reading. i did not find a ecu with the same code as mine to replace the hole unit…repairing mine is the only solution…i gues…
Double check the part numbers... a different part number does not necessarily means is not compatible... it just means is a different version but fully compatible... Do some research... I sometimes ask the dealers for help, by phone and ask if a certain part number is compatible... The will obviously not start due to the immobiliser... you need to transfer the data from your actual ecu into the replacement...
Great diagnosis and repair, would have been good to see you solder the chip back on! Just one bit of criticism on the video is you could do with a bit more editing. For example when you were trying to show the screen with microscope and started to look for something put the camera on, you could have just cut to the screen. Thanks for sharing the knowledge!
ViperDragon001 Hi I do really appreciate any suggestions... I don't do much editing on my videos... is what it is...

Good job, thanks for the knowledge. I want to ask because I'm very curious, on the ecu there are a lot of components why you are going to ic and what is resistence ohm is in good range? Thank you again
Melissa Haughney As I said in the video, all the components showing a fault, one of the connections was going straight to the IC... The circuit from the components up to the IC was fine, all below 1 ohm...
Hi From a proper garage... probably more than the car was worth... I do this as a part time and for the fun... so did not cost him that much... Thank you for watching and for your comment!
Ahmed Abd elbaky I have the MaxiSys for only a few months... It can do coding on some cars an programming on some others... but I haven't really tried it yet...
Hi Now that I know it is the siemens ecu, confirm that is the SIM4L KE... If correct, the immo on that ecu is actually stored in the flash memory, not eeprom, should be stamped as 29F800...
2001 w203 2.2 cdi. i am thinking about grounding the wire coming from the ecu and see if the alternator charges, i am still not sure if my regulator is bad now. this all happened maybe because of putting the battery on backwards. it wanst me doing it and ever since i have been having red battery visit workshop messages but charging, changed regulator=same result. To the point that now its charging 1 or 2 volts max ( it means no effective charge anyways), it wont go past 12 volts to the battery when at first error time i could get 14.5. So i am not sure if the computer got fried, if any wire may be broken or simply the regulator or diodes are bad. I do not get alternate current back but i havent tested with a scope. I saw scannerdanner grounding the wire that the ecu is supposed to send a pulse or intermitent ground shunt, can i do that on a bench to test my alternator spinning at around 800 rpm and conected to a battery? this would rule out if the alternator was bad if it produced around 14,4 dc volts right..? ive always worked on cars but these computorized stuff is time wasting sometimes even the dealer wont fix it. But of course you know that too. hope you can give me some hint or opinion, thanks
Jose Ferreira Ok... You can obviously test it on the bench, but should be no different on the car... If the alternator is good, it should generate current providing all the connections are good... On top of the 12v cable, the one that charges the battery, you should have some more thin ones, depending on the alternator, you have a sense wiring that also connect to the 12v, that feedbacks the battery voltage and tells the alternator to increase or decrease the charging voltage... There might be more wires, depending on the system... without looking at some diagrams is hard to tell... The battery being connected backwards is obviously not good... I supposed you have checked all the fuses etc?...
lmsvvavr yes all checked. My alternator is a 190amp delphi watercooled. Has the battery big cable and a plug with 2 wires. L and DFM. Its not easy to access the plug but i will try to plug some extension cables to test if the ecu is sending sinal and also if the alternator generates power by earthing the DFM entry
Steve Ashcroft Well spotted... my bad... I could clean it and put new solder... but this one was good.. you need it as the chip is also soldered underneath... Thank you for watching!
When i grow up i wanna be great as you are with electronics i have 381i e46 bmw i am working crank but wont start i check spark no spark i call a bmw expert because i didn't really as any scanner at the time that could scan it i didn't see the dme and get a unkonw error code something like 2048 i think check the dme we saw where water as got to it two pins broken connector al green thing is i would love to rey amd repair it use it to practice on with your help hopefully
My car keeps going in to limp mode but I have had egr valve clean I had dpf filter clean but no luck with it just seems to drop speed on a steep hill turbo seems to kick in late or a pip got a hole I don’t nho any help please
Hanif Abbasi Hi So, are you asking if is possible to remove immo on that ecu, is that correct? If is, possible no... bmw works through synchronisation with the EWS... I am saying this based on my general knowledge about it... I have not researched that particular one.... What are you trying to, what is the issue?
hi yes sir.i do have autologic. auto hex. BMW MULTI TOOL FROM CHINA. but never.did on bmw. pls forgive my ENLISH .VERY POOR. I AM IN USA. I NEED HELP TO FIND OUT CHEAP LOCATION.

It can do coding on some cars an programming on some others... but I haven't really tried it yet...
Hi Imsvvavr, great video mate, Please where can i learn to repair ECUs? i'm electronicien
.
Yes it's a Siemens.9637D9434 is the only chip with similar #
Hi
Now that I know it is the siemens ecu, confirm that is the SIM4L KE...
If correct, the immo on that ecu is actually stored in the flash memory, not eeprom, should be stamped as 29F800...
Very nice work mate
Thanks!
👍👍👍
Congratulations !!! Very good video - thank you. LIKE from Prague

Are you still working . I need advice
If I can help...

can an ecu problem not allow the alternator to charge?
Jose Ferreira
Which car are we talking about?
2001 w203 2.2 cdi. i am thinking about grounding the wire coming from the ecu and see if the alternator charges, i am still not sure if my regulator is bad now. this all happened maybe because of putting the battery on backwards. it wanst me doing it and ever since i have been having red battery visit workshop messages but charging, changed regulator=same result. To the point that now its charging 1 or 2 volts max ( it means no effective charge anyways), it wont go past 12 volts to the battery when at first error time i could get 14.5. So i am not sure if the computer got fried, if any wire may be broken or simply the regulator or diodes are bad. I do not get alternate current back but i havent tested with a scope. I saw scannerdanner grounding the wire that the ecu is supposed to send a pulse or intermitent ground shunt, can i do that on a bench to test my alternator spinning at around 800 rpm and conected to a battery? this would rule out if the alternator was bad if it produced around 14,4 dc volts right..? ive always worked on cars but these computorized stuff is time wasting sometimes even the dealer wont fix it. But of course you know that too. hope you can give me some hint or opinion, thanks
Jose Ferreira
Ok...
You can obviously test it on the bench, but should be no different on the car...
If the alternator is good, it should generate current providing all the connections are good...
On top of the 12v cable, the one that charges the battery, you should have some more thin ones, depending on the alternator, you have a sense wiring that also connect to the 12v, that feedbacks the battery voltage and tells the alternator to increase or decrease the charging voltage...
There might be more wires, depending on the system... without looking at some diagrams is hard to tell...
The battery being connected backwards is obviously not good... I supposed you have checked all the fuses etc?...
lmsvvavr yes all checked. My alternator is a 190amp delphi watercooled. Has the battery big cable and a plug with 2 wires. L and DFM. Its not easy to access the plug but i will try to plug some extension cables to test if the ecu is sending sinal and also if the alternator generates power by earthing the DFM entry
lmsvvavr let me know if i can safely do it even for some brief moments
Very good job it's not easy to do it .thanks mate I learn A lot of new things.

You never said why you don't clean the middle area under the chip
Steve Ashcroft
Well spotted... my bad... I could clean it and put new solder... but this one was good.. you need it as the chip is also soldered underneath...
Thank you for watching!
Oh It has pins underneath as well. So just the old solder stays there and that reflows to the pins?
Steve Ashcroft
Is not really pins... but yes, just reflow the base back on...
Wow serious determination

Thanks!
Weldone brother your a top G 👌

good job . wish product i use in order to clean corrosion from ECU for exemple
I use isopropyl alcohol... and a fiber glass pen...

Hello imsvar,
My renault clip v171 is asking me for tool serial number when i enter reprogramig mode, what should i do ?
Soufian Attar
Put the number that came on the label...
lmsvvavr din't work :-(
Is there anyway i can read the serial tool or know it ??
Soufian Attar
Have tried numbers from 1 to 7, or all zeros?
lmsvvavr you mean write "1234567" ?
Soufian Attar
Yes... or all zeros...
brilliant video mate you done really good
Paul Mayou
Thanks Paul!
any idea how to identify the eeprom on a 04 c230? id like to swap into a used computer
HiYou should be able to identify it through the writing on top of it...
they all have writing but dont know what im looking for
ed barry
Which ECU are we talking about?
It's a 05 Mercedes c230. I hv no injector pulse on cylinder 4
Found a guy local who says he can swap the eeprom for the key and vin
Couldn't be as simple as it has the last 6 of the vin on it or something
Exceptionally intelligent

hi sir good moring.i have 2004 x3 ecm45.1 pls can you tell immo.cheap numbers.i will be very thanks full.pls help us
Hanif Abbasi
Hi
So, are you asking if is possible to remove immo on that ecu, is that correct?
If is, possible no... bmw works through synchronisation with the EWS...
I am saying this based on my general knowledge about it... I have not researched that particular one....
What are you trying to, what is the issue?
hi yes sir.i do have autologic. auto hex. BMW MULTI TOOL FROM CHINA. but never.did on bmw. pls forgive my ENLISH .VERY POOR. I AM IN USA. I NEED HELP TO FIND OUT CHEAP LOCATION.
My problem was no injector pulse on # 4
ed barry
That's sound more like an hardware issue... so you should be ok...
your a clever man!!!!

Thank you... 😉
Good job true talent !!
