I have just now registered and I thought I’d bring to your attention to what could be a fatal issue on the underside on an audi a3.
I have a 2008 a3 cabriolet and recently had its yearly mot, failed, on one item, rust on front lower suspension area,small part and one advisory, a rear bush.
But when the garage took off the undertrays that cover the main chassis front to rear (both sides) it was found the the whole drivers side chassis was riddled with holes and passenger side, although better, had serious rust.
So my question is, how long did this took hold as this is not over 1-2 years and how damaging are the undertrays are as they hold all the moisture, crud, mud, and can’t be washed off with a jet spray.
The situation was, that it cost me just over £1000 for the garage to fabricate new panels but if the trays were not fitted it would have been noticed years ago and possibly rescued it before it got that bad.
Essentially if your ever thinking about buying an audi especially an cabriolet take off the trays before you buy as you could be looking at a whole lot of pain come mot time.
Thought I’d mention my situation and hope that I’ll find some useful info on here which I am sure I will.
cheers
Gary.
