I think its the ECU i have ordered a new one, but want to eliminate other things that could be , but I would need an wiring diagram for the Front suction (cooling) fan . I'm not able to find it on my wis asra .
I will have to thank S-Prihadi ON THE PREVIOUS THREAD HE HELPED A LOT . I managed to eliminate a lot of possibilities . Attached is my datacard , also thanks to S-Prihadi for the data card .
There are too many wiring schematic in 1 car, so you need to narrow it down what you want to go deep into.
You must have a proper scanner, which must be able to do bi-directional, otherwise you may end up wasting so much time if not parts you may mistakenly assumed as bad.
Depending on the issue, at times you need to have a scope ( oscilloscope ) too.
Proper DMM able to to read duty cycle and current clamp is a must have too.
You already have these from me at your earlier post:
Have fun reading that thread I linked ..............
Also, it is about time you get Ebay version of WIS/EPC of Mercedes, year 2020 is more than adequate.
These WIS/EPC have everything you need for schematic and most How-To.
The key is SPEND A LOT OF TIME reading and reading......... no other way.

Hello,
I do not found any wiring diagram for my 2011 W212 E350 CDI navigation module (A2049018201)
It looks like the highspeed CAN signal goes into the navigation module, but it doesn't comes out from it. I found the CAN signal cables are brown and brown-red, but I don't find a diagram with this cables.
The command display (A2129004900) doesnt works, and the head unit (A2129004910) has no backlight as well.
If anybody has the correct wiring diagrams for these area above please share.
Thanks!
Get your data card using your VIN number.
After that you will know what options/module on your car, and slowly edit out which modules or wiring IS NOT FOR YOUR CAR.
Its not too easy to sort things out, but it is what it is because MB sold so many variant of W212, so the diagram covers all of their W212 ( facelift and before )....you need to IGNORE which
ones do not apply to your car
