Audi TT Problems

Loss of Power Due to Torn Rubber Valve

The Audi TT 2.0T FSI engine looses power if the turbocharging system has a leak. The most common turbo boost leak is a torn rubber diaphragm on the diverter valve, which is intended to open only if pressure gets too high. Common symptoms are increased turbo noise when letting off of the gas pedal, power loss, and engine code P0234.

If there is a turbocharging system leak, the system will need to be inspected, and the defective seals and/or valve will require replacement. 

Rattling From the Transmission May Be Heard When Engine is Cold

The flywheel for the 2006-2009 Audi TT 2.0L Turbo is a non-conventional "Dual Mass" flywheel. It is known to make light rattling noise when the engine is cold, and should subside once the engine temperature raises. If the rattle doesn't go away when the engine warms, the flywheel may have failed.

If the dual mass flywheel has failed, the only solution is to replace the flywheel.

Check Engine Light and/or Hesitation Due to Failed High Pressure Fuel Pump

2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.

Audi TT Recalls

Potential Fuel Leak During Extreme Driving Conditions

Under extreme driving conditions, fuel can leak from the fuel tank vent valve. The internal spring may be too weak to hold the valve closed. Any fuel leak increases the risk of a fire. Dealers will replace the affected valve with an improved design. The recall is expected to begin by November 16, 2009. The Audi recall number is 20Q3/J3.

Automatic Transmission Shifts Into Neutral Without Warning

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.

Interior Side Trim Panels May Become Detached

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.

Audi TT Reviews

Bought a CPO 6-spd 225 with 39K that was my daily driver until I reached 291,000 in 6 yrs. No engine problems but needed new control panel by 200K, routinely maintained at dealership, still running well when I sold it 6 mos ago.
25,000 Dollar paper weight! My Audi TT sits out back broken for the last five years in like new condition [bad instrument cluster repaired three times!] [BOOST LEAK] [BAD WATER PUMP][AIR BAG LIGHT] [CHECK ENGINE LIGHT][BAD TEMP SWITCH][ect.] this car was garage kept and driven easy with the best of care! It was like pulling teeth to get 40,000 miles out of it! POS! Won't buy any Audi again!
Beautiful car, fun to drive, but some electrical issues, Instrument cluster, Coils....etc.
