2008 Audi TT Recalls
Two recalls cover the 2008 Audi TT. The most recent was issued in September 2009: “Fuel Tank Ventilation Valve.” A VIN check at NHTSA shows which are still open on a given car.
Fuel Tank Ventilation Valve
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. In the presence of an ignition source, a vehicle fire could occur.

C-Pillar Trim Cover
The detached trim cover could pose a risk of personal injury for vehicle front seat occupants.

2008 Audi TT Warranty Extensions and Programs
Audi has two warranty extensions and one service campaign for the 2008 Audi TT, separate from its recalls. All three are for problems with the engine. Whether one applies to a car depends on its VIN, which an Audi dealer can check.
- Warranty extension
Intake runner control motor and PCV valve faults
- The problem:
- Under certain conditions the intake manifold runner control motor and the PCV valve can work poorly. Fault codes may then turn on the check engine light.
- The fix:
- An Audi dealer runs a diagnosis scan and replaces the intake runner control motor and the PCV valve for free if needed.
- Who qualifies:
- Certain 2.0 TFSI cars: 2006 A4, 2007 to 2009 A4 and A4 Cabriolet, 2006 to 2008 A3, and 2008 and 2009 TT. Other causes of the warning light and damage from tuned engine computers are not covered.
- Coverage:
- 10 years or 120,000 miles from the original in-service date, whichever comes first.
- Warranty extension
PCV valve fault with check engine light
- The problem:
- Under certain conditions the positive crankcase ventilation, or PCV, valve can work poorly. Fault codes may then turn on the check engine light.
- The fix:
- An Audi dealer runs a diagnosis scan and replaces the PCV valve for free if needed.
- Who qualifies:
- Certain 2.0 TFSI cars: 2006 to 2008 A3, 2006 to 2009 A4, 2007 to 2009 A4 Cabriolet, 2008 and 2009 TT, 2009 to 2011 TTS. Other causes of the warning light and damage from tuned engine computers are not covered.
- Coverage:
- 10 years or 120,000 miles from the original in-service date, whichever comes first.
- Service campaignAudi 24T3
Intake runner control motor replaced before failure
- The problem:
- The intake runner control motor, also called the intake manifold flap actuator, may fail on 2.0 TFSI engines built in a certain period. The campaign aims to prevent this.
- The fix:
- An Audi dealer checks the motor's part number. If it does not match the numbers Audi lists, the dealer fits the new part.
- Who qualifies:
- 2.0 TFSI cars in set VIN ranges: 2006 to 2008 A3 and A4, 2007 and 2008 A4 Cabriolet, 2008 TT. The campaign must still be open on the car's VIN.
- Coverage:
- Free while the car is still within the intake runner motor warranty extension. Ask an Audi dealer for the exact terms.

Confirm the Recalls Were Done
Ask the seller for proof that each of these recalls was repaired.

Ask an Audi Dealer
Ask whether each of these warranty extensions applies to this VIN, and whether the work was done.

On the Test Drive
- Accelerate gently from a stop and again at 20 to 40 mph. Shudder, slipping or harsh shifts are warning signs. Ask for the transmission fluid records.
- Brake firmly from a moderate speed. A soft, hard or pulsing pedal, or a brake warning light, is a warning sign.
Ask the Seller
Ask whether any of these were ever repaired, and ask to see the receipts.
- Dual-clutch transmission
- Taillights or brake lights
- Also ask for the service records, especially oil changes and transmission fluid changes.
Before You Pay
