Porsche PCM

Hi

After a flat battery / Sunday morning alarm incident I've got a problem with the PCM / BOSE audio system in my 53 Boxster. The speakers 'pop' every 10 seconds or so before the key is in the ignition and the PCM unit only turns on intermittently. There is also a constant drain across the battery which disappears when I pull the fuses for the audio / sat nav.

I've got three questions for you:

1) Firstly, any ideas on what the problem may be and any suggestions as to how to fix it (other than going to the dealer for a new unit)?

2) If I have to replace the PCM, anyone know where these can be purchased second hand?

3) Do you know of any aftermarket replacements for the PCM unit?
