Do you have any ability to scan this with a piwis tester? Yes the amps go bad but I would like to know some things the piwis tester could tell us. Sometimes these had an update to fix problems like this

What the heck is a piwis tester?. I am assuming this is something a technician would have,so I do not have such without going to someone who might have such.
Porsche Mechanic: porscheguru, Porsche technician replied 2 years ago

Let me look for a bulletin and we can see if a software update will fix your problem. I need just a little bit of research time. I might need the numbers or a pic of the label on the amp. Hang a bit for me please

I can offer you a phone call service if this helps? It is a small but worth while additional fee

Porsche Mechanic: porscheguru, Porsche technician replied 2 years ago

Were you able to download the document for the software update on the amp? I want o walk you through it because there is a translation issue in one part where you hold a serious of buttons to determine the software level.
