Hi peeps!

I've got some faults on a 2001 A3 1.8T as follows:
Electric sun roof sometimes opens, sometimes doesn't (usually doesn't)
Driver's electric window won't open
The dashboard often shows the driver's door being open when it isn't
The alarm makes noises from the rear - sometimes
The car just had its MOT (passed) and the mechanic said that the problems may be linked, possibly due to moisture ingress somewhere.

Does this ring a bell with anyone and does anyone know of any recalls on this model?

Grateful for any help! Tim
