Audi A4 Allroad 2009 - sunroof to drivers foot well leak.

Hi There,

I have an Audi A4 Allroad (B8) 2009 that has been collecting rain in the drivers foot well in the recent heavy rain.

It's been into the Audi main dealer today who charged me 60 UK pounds to do an initial investigation. They have identified the leak is coming from the sunroof but want another 500 UK pounds to remove the inside of the roof to trace the leak and fix it. Are there drain plugs that need cleaning? Where is the sunroof rim meant to drain to?

I'm not prepared to spend that much and wondered if anyone else has come across this who might be able to advise anything I can do myself?

Any tips? Where to get workshop manuals etc?

Cheers

Rob
