2004 Audi TT Reviews
transmission just went out at 42K miles and will cost 7grand to replace. Nice. No help from AUDI even given the low miles. INstrument cliuster failure at the same time, that's another grand to fix. I missed the class action law suit extension of warranty by a few months. Nice. Will never buy audi again. Lots of reported electrical issues and now a new Tranny already, insane.
