Water leak was, and still is a well known problem with Audi:
Audi A6, A8 and Q7
with amplifier and sunroof as a standard, are prone to water leak through ceiling.
Mostly common with early models from 2004 to 2010 ish,
but doesn't mean new models are completely safe from such leak.
We've done diagnostic & replacement of 3G MMi Circuit board,
and Amplifier from
MY12 Audi Q7
Which experienced s
evere water leak on both audio controller,
and Amplifer in trunk area.
Amplifier with Water leak:
