My 2001 Audi TT recently started with many electrical problems. I was thinking it might be due to the rear window in the rag top leaking. My gas cap wont open, windows don't work properly, door locks and alarm don't work, trunk doesn't open, interior lights work sometimes, top doesn't go down and of course the instrument cluster's screen is illegible but i don't think its related to the above. Any idea how to fix?

 

Hi,
I read with interest the electrical faults you list on your Audi TT, I am having almost identical faults with my 1998 1.8 TT convertible.
I am sorry I can't offer any solutions but am very interested if you have had any luck sorting your TT since making this post?
Len.

 

I have the same exact issue. Has anyone figured this out?
