Greetings, 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.
