B6 Dynaudio Amplifier Issues 3C0035456C

[rcracer]

Welp, a few months ago I went through the car wash had water leak though the sunroof into the interior and ultimately onto the amplifier that is mounted under the driver seat. The amp was dead for about a day. Once it dried out, it miraculously came back to life. The only problem is that only the driver's side speakers work...everything is still hooked up.

I'm not really sure where to go on this one. The stock Dynaudio system is really good and I would like to keep it but my decision isn't easy. The lowest price I could find for a brand new amp 3C0035456H (original part super-ceded) is a little over $700. Finding this unit used is next to impossible.

If anyone has any suggestions on repair or knows of someone with a replacement please let me know.

Here is the log from VCDS:

anyone?

Looking at the dates of these faults occuring, they seem to show over a period of months last year?
Have you cleared the codes and done a re-scan? Then you'd at least be uptodate of today's situation
Use either the beta or 11.5 from the Ross-Tech site. Unfortunately some modules are not so good at reporting dates as they should be

The faults are still occurring. I double checked the wire harness that runs from the radio to the amp. There are no breaks in the wire (both 12v and grnd) and the amp is getting 12v on all power leads. I guess that just leaves the amplifier. I just have a hard time believing that part of the amp is not working (part that drives the passenger front and rear bass speakers).

Doesn't seem too hard to believe to me. It got wet, and the parts that got wet failed. Time to go shopping!
