Had an amp not availiable message once after i replaced the batt, a shutdown/startup corrected it that time.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Looking for ideas, suggestions on this one... Discovered the mysterious complexity of the PCM in my 2004 TT. Give me a multi-dimensional database over this system any day. Getting a System Error: amplifier, CD changer not available Radio seems to be working (station signals coming in, but no sound) Using an updated Version 3 PCM OS. Radio functional but no sound except for the faint pop on power-up. I've heard about MOST rings, (fiber optic network in a token-ring configuration?) My Durametrics says 9114 control unit Status" not present. So what does that mean? Sounds like a handshake problem, but how to resolve without going to P hell (Porsche dealer) HELP!!!! Drift

POST 4Original post

It looks like you have a 2002, 3 or 4 if it is the car in your avatar. I have an 03. When I first got mine the battery was weak. If I left the sound system on when I turned the car off the system would not boot correctly on restart. The display would light and tell me it could not find the remote CD changer or the amp would be lost in space. The only way I could get them to play together again was to reboot things by removing fuses D8 and 9 for a few seconds. I got in the habit of turning the system off before I shut the car down and waiting 1 minute before turning it on after starting. Lately it has been behaving, still shut it off before the car.

This is a source reference. Confirm exact model applicability in the original material.
