NHTSA lists 2 safety recalls and 14 owner complaints for the 2008 Audi TT. Most complaints involve power train (4) and exterior lighting (2). The EPA rates it 19–26 mpg combined.
VOLKSWAGEN IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2010 AUDI A3, TT, AND TT ROADSTER PASSENGER VEHICLES MANUFACTURED BETWEEN SEPTEMBER 29, 2005 AND AUGUST 26, 2009. THE CLOSING FORCE OF AN INTERNAL SPRING OF THE FUEL TANK VENTILATION VALVE IS NOT ADEQUATE ENOUGH TO HOLD THE VALVE CLOSED UNDER EXTREME DRIVING CONDITIONS POSSIBLY ALLOWING FUEL TO LEAK.
VOLKSWAGEN IS RECALLING 720 MY 2008 AUDI TT COUPE VEHICLES. THESE VEHICLES WERE PRODUCED WITH C-PILLAR TRIM COVER CLIPS THAT DO NOT PROVIDE ADEQUATE RETENTION. IN THE EVENT OF A DEPLOYMENT OF THE REAR PYROTECHNIC SAFETY BELT, THE C-PILLAR TRIM COVER MAY BECOME DETACHED FROM THE SHEET METAL DUE TO LOW RETENTION FORCE OF THE TRIM CLIP.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“I HAVE A SILVER TT 2008 WITH AUTO GEARBOX. I'VE HAD IT SINCE APRIL 20TH THIS YEAR! PROBLEM IS, IT JERKS AND BUNNYHOPS WHEN PULLING OFF, REVERSING AND MOVING IN SLOW TRAFFIC. IT GETS WORSE AFTER THE CAR WARMS UP AND IS A NIGHTMARE TRYING TO PARK IN TIGHT SPACE , NO MIL OR CODES ,AUDI DEALER COULDN'T FIND ANYTHING WRONG WITH THE CAR , GOING TOMORROW TO A DIFFERENT AUDI DEALER HOPEFULLY THEY HAVE BETTER KNOWLEDGE OF THIS ISSUE. *TR”
“TL* THE CONTACT OWNS A 2008 AUDI TT. THE CONTACT STATED THAT THE DRIVER'S SIDE TAIL LIGHT FAILED. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHERE IT WAS FOUND THAT THE SOCKET HAD MELTED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE AND VIN WAS NOT AVAILABLE.”
“MY 2008 AUDI TT WOULD CONSTANTLY BEEP WITH "RIGHT REAR LIGHT" OR "LEFT REAR LIGHT" WITH AN X THROUGH A LIGHT BULB SYMBOL POPPING UP ON THE SCREEN IN BETWEEN THE TACHOMETER AND THE SPEEDOMETER. IF I APPLIED THE BRAKES, THE X THROUGH A LIGHT BULB SYMBOL WOULD GO AWAY. IT TURNS OUT THAT THE LIGHT THAT IS FARTHEST OUTBOARD IN THE TAIL LIGHT HOUSING (ON BOTH LEFT AND RIGHT SIDES) WAS THE PROBLEM. I FOUND THAT THE PROBLEM WAS WITH CORROSION WITHIN THE CONNECTORS THAT GO DIRECTLY TO THE TAIL LIGHT HOUSING. IT APPEARS THAT THE GROUND WIRE IS MUCH LARGER THAN THE OTHER WIRES, BUT THE SIZE OF THE CONNECTOR IS THE SAME. THE WIRE HAS TOO MUCH CURRENT FOR THE CONNECTOR TO HANDLE. IT MELTS THE PLASTIC AROUND IT AND BECOMES CORRODED AS A RESULT. IF YOU GOOGLE "AUDI TT TAIL LIGHT PROBLEMS" YOU WILL SEE THAT MANY OTHER CONSUMERS HAVE THIS ISSUES, WITH SOME EVEN REPORTING FIRES IN THEIR TAIL LIGHTS. I REPORTED THE ISSUE TO MY LOCAL AUDI DEALER AS WELL AS AUDI CORPORATE. THEY WILL NOT REPLACE THE WIRES, AND THEY WANT TO CHARGE ME $90 JUST TO DIAGNOSE THE ISSUE, AND UP TO $900 TO REPLACE THE TAIL LIGHTS. THIS IS ABSURD, SINCE IT IS A POORLY ENGINEERED DESIGN THAT RESULTS IN A VERY…”
