Hello, I have a problem with the n47-5 module. I started fixing it. It had damaged transistors 1x 55N055 and 2x 32N055. After replacement and installation, it does not show errors, but after firing and accelerating to a speed of 10-20 km / h, it throws all errors on the clock. ABS/ABR/ESP etc. On C4 n47-5 shows no errors. Errors have occurred on SGR - 7409 -CAN BUS no information received from n47-5 and NSA -5097 CAN BUS FAULT Control module is in passive mode due to esp error. If anyone knows what the problem is, please help or diagram n47-5 w221 modul A2218405232. All sensors are operational because after installing a functional module, the car has no errors and drives without a problem. The problem is in the module itself.

faulty module is not normal, faulty wheel speed sensors is standard, is this a crashed one that being repaired - merc don't approve fixing crash modules

I agree with you. Mercedes does not provide repair. But the module is an electronic part that can be repaired and I know others fix them. After the failure, I have a new n47-5 module on which I drive and the old / damaged / I am trying to repair only for myself /. I opened it, found and replaced the damaged elements 55N055 and 32N055, but as it turns out, that's not all. I don't have a schematic and looking for in the dark will take some time. So please help.

I am not entirely sure, but when my ABS module went, they installed a new one and had to code it to my car. Do you have a scanner that can virginize your module?

I have c4 and I can transfer data from module to module. I want to find and replace - only a damaged electronic component. There will be no need for programming. The processor and software remain intact. I need the n47-5 scheme for w221 2007 As I wrote above. I found on the forum such a diagram for w204 so maybe someone has a w221. The problem is blocking the signal from n47-5 after CAN for NSA and SGR
