Need some help diagnosing to fault codes in my ECM Module.
2005 Porsche 997 Carrera S Cab
U0155: Lost communication with Instrument Cluster Control Cluster.
U0146: Lost communication with "Gateway A"
Searching Google only found two other Porsches with the same issue and they were undiagnosed. Now searching those faults individually found other vehicles had those faults when cracks developed in the Instrument Cluster solder joints, people disassembled their Instrument Clusters, resoldered all the joints and the fault went away.
Has anyone else had these faults or experience with them. I recently relocated from Arizona with glass smooth roads to the Los Angeles area and the roads are horrible!!! Just in the last 3-weeks my drivers door lock assembly failed and window goes up and down like crazy and difficult to lock door, I believe this failed due to the rough roads, these faults also developed at the same time, which leans me towards cracked solder joints in the Insteument Cluster. Car runs and drives fine, just have these faults now.
I was doing some maintenance work and hooked up my Durametric and tested all modules. I got a fault in the PDK module I had not had or seen before.
It was Durametric Fault Code: 50200, which the folks at Durametric said was described as U0418: CAN fault, brake.
Anyone have more information or details about this? As an aside, the PDK seems to be just fine in all phases of operation, so I am wondering if this is a non-event.
