What could be causing this distortion on my A6 audio.

Today I have noticed distortion appearing on music playing through the stereo on my MY05 A5 2.7 TDI SE.

The Stereo is a 'bog standard' one but it does have 6CD multiplayer and full colour DVD nav.

• The only way to describe the distortion is like a 'halo' of noise / crackle / hiss around mid - hi frequencies, especially if they're sustained notes. It's not too loud but I can notice it and it's very distracting.
• It also seems to be more from the front 'speakers than the rear (ie if I set fadar to full rear I can't hear it as much) but it may be that the rear 'speakers reporduce less high-frequency sounds.
• It seems to be equal in both
• I hear the problem more on CD but it's there on radio.
• Volume doesn't affect the problem, nor does turning down the bass or sub setting so I think I can rule out speaker distortion.
• All of the other features (nav etc) work fine.

I think it's a problem with the amplifier module. What do you think? Any way I can diagnose it or should I take it into a car audi specialist?

If I need to change the amp, is there a better amplifier unit I could use rather than the stock Audi one? Or could I u/grade to a BOSE setup?

Does your A5 have rear wash/wipe? There are lots of reports from Avant owners of rear washer pipes splitting and showering the amp with water. Just wondering if you might have a similar issue?

Thanks for the reply.

It's an A6 saloon so no wash-wipe to worry about.

I checked the cubby hole in the boot that the amp / nav sits in and it didn't seem to be too damp in there.

If I can't find someone to diagnose the problem (I am loathed to take it to Audi for this, I shudder to think how much the diagnostic will cost) I think the only option is to swap out the amp and see what happens but I don't have one spare.

Unless anyone can recommend an auto electrician / car audio specialist in Northants or surrounding area who could help.
