Hello.
Sorry for my bad english.

I have a very big problem. My C300 2015 4MATIC has been damaged. The shock is mainly at the level of the front face. The vehicle still started after the accident.
However I was forced to leave the car parked at home for about 9 months without touching it for some reasons.
I finally had the time to dedicate myself to it. But when I tied to start it it stops responding. The gear selector is not visible on the dashboard. Impossible to know if it is on P N R or D. I then did a scan with my autel scanner and the bad news is that I noticed that 70% of the DTC codes talks of a communication error.

Notably:
- U014100 Communication with the electronic ignition lock has malfunction
- U012600 Communication with the steering column module has a malfunction
- U0100FF Communication with the unit 'combustion engine' has a malfunction
- U105CFA Communication with control unit 'COLLISION PREVENTION ASSIST' has a malfunction
- U0101FD Communication with the control unit 'Transmission' has a malfunction
- UF0101FF Communication with the control unit 'Transmission' has a malfunction
- U0100FB Communication with the unit 'combustion engine' has a malfunction
- U0100E1 Communication with the unit 'combustion engine' has a malfunction
- U0100FC Communication with the unit 'combustion engine' has a malfunction
- U0100FA Communication with the unit 'combustion engine' has a malfunction
- U0100FD Communication with the unit 'combustion engine' has a malfunction
- U011587 Communication with control unit 'drivetrain' has a malfunction
- B210313 Input 'Circuit 15R' has a malfunction. There is an open circuit.

- ETC... There is so many communication error code...

I know I have a comunication error.

Can you help me to follow steps in order to be able to repair this car ? Thank you.

 

Are you able to post any pictures of the damage?

 

Of course.

 

did you figure out what was the problem, i have the same problem here

 

For me It was the two wire (pink and green) of the Electronic Steering under the car that was short. I replace the wire and the car crank, p r n d is back too.

 

Hello,
Is it that big round power motor under the vehicle that the cables got shorted?
