NHTSA lists 2 safety recalls and 12 owner complaints for the 2009 Audi TT. Most complaints involve power train (4) and electrical system (3). The EPA rates it 20–26 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 CERTAIN MODEL YEAR 2009 AND 2010 PASSENGER CARS MANUFACTURED BETWEEN SEPTEMBER 2008 AND AUGUST 2009. THE WIRING HARNESS OF A TEMPERATURE SENSOR IN THE DIRECT SHIFT GEARBOX (DSG) MAY HAVE CONNECTOR WIRES THAT WERE INSUFFICIENTLY CRIMPED. WITH INSUFFICIENTLY CRIMPED CONNECTOR WIRES, A TEMPERATURE SENSOR HAS THE POTENTIAL TO FALSELY DETECT A HIGH GEARBOX OIL TEMPERATURE, CAUSING THE TRANSMISSION TO ABRUPTLY SHIFT TO NEUTRAL. IF THIS HAPPENS, THE SELECTOR LEVER POSITION INDICATOR WITHIN THE INSTRUMENT PANEL WILL FLASH. IN ADDITION, THE "DEPRESS BRAKE PEDAL" INDICATOR LIGHT WILL BE ILLUMINATED, ALERTING THE DRIVER TO APPLY THE BRAKES.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“I'VE EXPERIENCED ISSUES WHEN TRYING TO SHIFT GEARS, MOST RECENTLY WHEN PUTTING THE CAR IN REVERSE FROM DRIVE, THE DASHBOARD STARTED FLASHING AND IT LOST ALL POWER AS IF IT WERE DISENGAGED OR IN NEUTRAL. I TOOK THE CAR INTO A DEALER AS THIS IS A SAFETY ISSUE AND WAS TOLD THAT THERE WAS A RECALL ON THIS ISSUE FOR MY VIN ( CAMPAIGN 09V333000), BUT THAT IT HAD ALREADY BEEN REPAIRED PRIOR TO MY OWNERSHIP, WHICH DOES NOT SEEM TO BE THE CASE.”
“HAD ISSUES WITH THE REAR TAILLIGHTS GROUNDING ISSUE CAUSING THE GROUND IN THE CONNECTOR TO MELT AND SHORT OUT CAUSING THE TAILLIGHT TO NO LONGER WORK. THIS WAS AN ISSUE FIRST ON THE DRIVER SIDE THEN THE OTHER 6 MONTHS LATER. BOTH REPAIRED LOCALLY BY ADDING AN ADDITIONAL GROUND WIRE AND REPLACING THE CONNECTORS.”
“THIS IS THE UTMOST FRUSTRATING SERIAL OF INCIDENT I HAVE EVER ENCOUNTERED WITH AN AUTO MANUFACTURE COMPANY - AUDI. I HAVE TRIED TO PUT MY FAITH AND SAFETY AGAIN WITH AUDI, BUT THEY HAVE COMPLETELY FAILED ME LEAVING ME AND FAMILY IN DANGEROUS AND PARANOIA. MY AUDI 2009 TTS WAS PROBLEM FREE UNTIL 4,000 MILES. OUT OF ORDINARY, THE ENGINE LIGHT CAME ON AND THE DEALERSHIP INFORMED ME THAT THE FUEL SEAL WAS LEAKING AND NEEDED REPLACEMENT. THIS INCIDENT WAS VERY SIMILAR WITH MY 2009 A3 INCIDENT (ODI #10281829). I HAVE SINCE BEEN EXTREMELY PARANOID WITH MY NEW TTS AS THE A3 HAD LEFT ME VERY FRIGHTENING EXPERIENCE AS IT HAD COMPLETELY LOST POWER ON THE HIGHWAY. AT AROUND 14,000 MILES, I HAVE NOTICED A TICKING SOUND BY THE REAR DRIVER AREA. THIS WAS THE AREA THAT THE DEALERSHIP HAD WORKED ON AT 5,000 MILES WITH THE REPLACEMENT OF FUEL SEAL. I HAVE NOT THINK MUCH OF IT AS THE CAR WAS STILL RUNNING AND IT WAS APPROACHING THE NEXT SERVICE INTERVAL AND I THOUGHT I CAN JUST HAVE THE DEALERSHIP CHECK THIS PROBLEM THEN. HOWEVER, TODAY, I WAS DRIVING LOCALLY WITH MY GRANDMOTHER IN LAS VEGAS. THE TICKING SOUND WAS STILL THERE AND THE TTS ONCE AGAIN COMPLETELY FAILED ON THE LOCAL…”
