2000 Audi TT Quattro Problems

No Start after Refueling and Popping Noise from Trunk

Popping sounds from the rear of the vehicle may be heard moments after starting the engine, or when slowing to a stop. This noise is from the leak detection pump filling the fuel tank with air, and releasing to retest the system when it finds a fault. The sequence of faults identifying this issue are as follows:

  • Succession of loud pops from rear of vehicle
  • Pops go away, and fuel economy decreases 
  • Check engine light illuminates
  • OBD trouble code P2404 and/or P0441 is stored
  • Engine will not start after refueling (must crank for over 30 seconds)
  • Vibration when slowing to a stop

The cause is a valve which is mounted on the front of the intake manifold, commonly called the N80 valve, or EVAP system purge valve. The valve is designed to open under specific circumstances, but a worn valve will remain open at all times, preventing the pressurization of the fuel tank. 

Correction of the issue is to replace the N80 valve with the latest revision. 

Engine Misfire Due to Failed Ignition Coil and/or Spark Plug

An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light.

Check Engine Light Due to Vacuum Leaks, Oxygen Sensor, or Catalytic Converter Fault

Vacuum leaks, oxygen sensor failure, and catalytic converter efficiency faults can cause the Check Engine Light to illuminate.

2000 Audi TT Quattro Reviews

Rated
based on 2 customer reviews
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.
Love the car!! Got it used and get awsome comments from my classmates. Very reliable
