Hi, My PCM is not working. Porsche have done diagnostics and state that the microprocessor has blown and as such I need to replace it. Has anyone had such issues? Is it something that can be fixed? First I had problems with my battery, then the side lights and then the PCM stopped working. They said the other issues were because of the blown microprocessor of the PCM and if I replace the PCM all other faults will be fixed. It is costly to replace the PCM so I don't want to replace it if the root cause is not fixed and the microprocessor blows again! Any advice will be appreciate.
