“I purchased an Audi TT with 40,000 miles on it in january of 2004. It burns 2 quarts of oil every 800 miles. Audi is unable to fix the problem and it has been to the shop at least 15+ times for the same problem. No one will help me and I never have my car. They give me loaners until they can fix it, which they have not been able to do it 11 months. I need help and have no where else to turn to. Please help!”

NHTSA complaint #10153462, filed 2006-03, 47,200 miles“On our Audi TT 2001 convertible, the electrical outlets underneath the dashboard caught on fire.

Also, prior to this fire, the tip of the spark plug fell into the engine cylinder block, causing us the owners to pay in full for a new engine head to be replaced....lots of money (approximately $8000). We replaced it through a well known professional Audi shop auto haus munich in san diego. Hazardous lights needed to be replaced professionally because it interfered with the signal lights. …”
NHTSA complaint #10333910, filed 2010-05, 96,800 miles“(1) events leading up to the failure of my timing belt were normal driving conditions, ie no sounds, smells, or visual damage. (2) on 01/15/2007, my timing belt broke while driving. The consequences are damage to the cylinder head, as well as other parts of the engine. (3) last year, Audi changed the time/mileage needed in order to change timing belt from 106,000(as stated in the owner manual, of the Audi TT) to 60,000-70,000, according to an employee, I spoke with. I asked the dealership if any notices; mail, e-mail, or phone, were sent out, and their response was, no. …”
NHTSA complaint #10186435, filed 2007-03, 85,000 miles“Purchased a 2001 Audi TT 225 coupe on october 2000, eight years later and only 69700 miles,timing belt fails causing major damage to the engine. August 2008 Audi sent out a letter acknowledging a potential problem with the timing belt but since it was not a recall I paid only a small attention to it. Besides all this clearly the design of the timing belt is faulty or inadequate to be used on a sports car!!!”
