Vacuum leaks, oxygen sensor failure, and catalytic converter efficiency faults can cause the Check Engine Light to illuminate.
An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light.
A creaking type noise may be noted from the front suspension. Replacement of the front sway bar may be required to correct this issue.
The water pump may fail resulting in engine overheating and possible timing belt damage. Overheating and/or timing belt failure can result in very expensive engine repairs. As a precaution, it is recommended to inspect the timing belt and water pump at regular intervals.
Audi TT Quattro Recalls (Recent)
RepairPal Expert Overview:
The retainers clips for the C-pillar trim panels may not retain the panels sufficiently. In a collision, the trim panel may become a projectile and injure an occupant. Dealers will install an improved retainer clip. The Audi recall number is 70D1/JX. This recall began on March 7, 2008.
RepairPal Expert Overview:
Connectors for a temperature sensor inside the direct shift gearbox (DSG) transmission may have been insufficiently crimped. They could incorrectly read a high transmission oil temperature, and abruptly shift into neutral. The shift position indicator in the instrument panel would begin to flash and the "Depress Brake Pedal" indicator light will be illuminated to alert the driver to apply the brakes. The abrupt shift could lead to a crash. Volkswagen and Audi dealers will reprogram the transmission control module (TCM) with updated software. The recall began October 20, 2009. The Volkswagen recall number is 37E3/S7 and the Audi recall number is 37E5/J7.
RepairPal Expert Overview:
The rear track control arm bushings may corrode, which can restrict proper movement of the track control arms. This can lead to handling issues. Dealers will replace the rear track control arms.
Audi TT Quattro Questions and Answers
I'd been having an intermittent problem with my car deciding to suddenly not restart after short drives. And a couple weeks ago it quit starting all together. The mechanic had it for a week, ...
my battery was dead so i jumped the car and now it will not go over 10 miles per hour and when I press on the gas nothing happens
How many miles would you expect to get before replacing a turbo. What would be a sign of impending failure? Looking at a quatro with 153k miles, well maintained.
When I run the car cold (as it needs to be), and I shift into 2nd, it get an audible grind (but the gear catches fine). As the car warms up, the sound disappears completely on 2nd gear shift. Occas...
I fear my 2nd and 3rd gear syncro's are on their way out, I'm going to do a transmission fluid replacement ASAP to see if my gear grinding shift problems are solved. However, just in case...
Audi TT Quattro Reviews
2011 Audi TT Quattro Coupe: three times in 7000 miles I suffered through ignition coil failures. First time at 26000 miles, second at 31000, and third at 32000. Each was a different ignition coil, and all three were replaced under warranty. But, I was not told by the service rep at the Audi dealer that Audi recognized this as a continuing problem, until after the third failure. During the third service, the final two were replaced with the new part number, and I was "assured" that this would resolve my problem. If you own a 2011 TT, you might want to inquire of your dealer's service dept. about possible switching out of the old part number with authorized replacement part.
Great car loved it so I bought a newer one 2008 with 3.2 love it even more.
Love my tt,but can anyone tell me what is wrong with it? It has a banging sound which only makes a noise in 1st gear on acceloration.It sounds like it is coming from the front driver's side wheel.It is not the gearbox,could this be a strut top mount or a bush of somekind.It has been to the garage and they are having difficulties in finding the problem.I have been told that everything is fine,obviously not as i can feel the knock through the footwell.

2003 TT Quatro 6 speed manual: Headlight low beams occasionally don't work. Replaced both balast & both bulbs ($300 parts); lights still don't work regularly. Dash indicator shows headlight out when they're both working. Can't seem to fix this headlight problem - got pulled over several times for no headlight(s). Often try to start engine & alarm goes off. At 115k miles the shifter fork broke inside manual transmission leaving the car stuck in first gear; $2,500 repair at local shop.
I am generally happy with the car, but I have had a rear control arm break 4 times in the last 2 years. This part was recalled in 2002, but apparently was not replaced with a sufficient part. Every mechanic has commented on how light-duty the part seems. Audi International and the local dealer have been difficult to deal with.
