I was resetting my service reminder when I noticed the following codes on my PDK box:

 

U0155: CAN timeout instrument cluster

U0146: CAN timeout gateway

U0418: CAN fault brake

1990: Positive engine torque intervention not possible

U0423: CAN fault instrument cluster

 

The car seems to run fine but I can’t clear the codes with the durametric and a battery reset didn’t help either. Any ideas?

 

Thanks for any pointers you may have. Hoping I’m not in for a $$$$ bill.

Thanks Loren. Is there a diagram of the CAN bus somewhere? It seems a common element in many. Perhaps the plug into the PDK is old/faulty?
