Does anyone have any information on where I could get my PCM serviced? The unit is turning itself back on after shut down. Porsche dealer wants to replace the entire unit ($$$$). They found fault codes indicating issues inside the PCM. It is manufactured by Becker/Siemens.

I pulled unit myself and sent to a knowledgeable indepedent electronics shop. They did diagnostics with Becker and found the problem to be on the Siemens side. They claim it must be shipped directly to Siemens.

I have been unable to find a Siemens center to service what seems to be a fixable problem.

Any info is greatly appreciated.
