2001 Audi TT Problems

What owners report

Owners of the 2001 Audi TT most often describe failures of the instrument cluster: fuel, speed, tachometer and temperature gauges that read wrong or stop working, sometimes leaving a driver stranded without fuel. Many say clusters were replaced under warranty and later failed again, and several note the cost falls on the owner once the car is out of warranty. Other recurring reports involve air bag warning lights and non-deployment, timing belt failures, and brake and rear suspension problems.

   Instrument cluster and gauge failures

   • 64 complaints (53%)
   • median 50,000 mi at 7.1 yrs old (39 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $1,000 (median of 6 quotes)
   • filed 2001–2015

   Owners report that fuel, speed, tachometer and temperature gauges begin reading incorrectly or stop working altogether, and that warning lights such as low oil pressure come on when nothing is wrong. Several describe running out of fuel because the gauge still showed a quarter tank or more. Complaints say dealers diagnosed the whole cluster as needing replacement, quoted roughly $600 to $2,000 plus labor, and that replacement clusters sometimes failed again within months. Some owners mention a class action settlement or warranty extension covering the part, and say their car fell outside it. Reported from very low mileage up past 100,000 miles, with many complaints between about 20,000 and 85,000 miles.

   What to check: With the key on, confirm every gauge sweeps and settles at a plausible value, and check that the odometer, trip meter and warning lamps illuminate. Ask whether the cluster has ever been replaced and keep in mind a replacement may later fail the same way.

   2 excerpts from owner complaints in NHTSA records

   “Instrument cluster digital display has faded out and is not displaying top two sections of the digital readout. Tachometer has failed. Failure causes inability to read the warning lights, such as low oil, high temperature, etc. I have purchased an instrument cluster at a cost of $650, and will soon be paying $225 to get it installed. I am frustrated with Audi for not issuing a recall on this unit.”

   NHTSA complaint #10261300, filed 2009-03, 100,000 miles

   “Instrument cluster resets date, time. Fuel gauge malfunctions to read empty when full, and reads RPM inaccurately. Began a couple of years ago and not often, now it's a daily problem. On a recent trip I wanted to top the gas tank, but the center isle controls for the gas cap and hatch door failed to work forcing me to continue with the available gas in tank. Once I arrived, both gas cap and latch door opened.”

   Air bags

   Air bag warning light on, bags not deploying

   • 9 complaints (8%)
   • median 40,675 mi at 9.5 yrs old (9 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2003–2024

   Complaints describe the air bag warning light staying on continuously or coming on intermittently, with diagnostics pointing to a failed air bag control module or cluster-related fault that can leave the bags and belt tensioners inactive. Some owners report that bags did not deploy in frontal collisions, and that replacing the module or cluster restored the light only briefly before it returned. Others describe a control module failure diagnosed outside warranty with a repair estimate over $1,000. Reported from around 15,000 miles into the 90,000-mile range, often several years after purchase.

   What to check: Check that the air bag light comes on with the key and goes out after the self-test, and ask whether the driver inflator recalls have been performed by an authorized dealer; a scan tool can read stored air bag fault codes.

   “Failure of the air bag control module on our 2001 Audi TT. This failure , if not repaired, will lead to the air bag system on the car not working Audi refuses to help with the repair, which is over $1000. We feel this safety issue should be repaired by Audi.”

   NHTSA complaint #10406978, filed 2011-06, 27,097 miles

   “My 2001 Audi TT roadsters airbag did not deploy during a direct frontal collision. The collision force was enough to shear the aluminum bumper reinforcement in the middle as well as wrap the radiator around the front of the engine. The vehicle is still in for repairs which now total over $13,000. In early 2003 I took my car to the dealer to investigate the airbag warning light. On the third (3rd) visit they replaced the airbag control module. I am concerned the airbag did not deploy because of a system failure?”

   Engine cooling

   Timing belt failure and engine damage

   • 6 complaints (5%)
   • median 64,700 mi at 5.9 yrs old (6 state mileage, few)
   • filed 2005–2008

   Owners describe the timing belt or its tensioner failing without warning while driving, which stops the engine and in several cases damaged the cylinder head. Complaints say the recommended replacement interval was shortened from the original manual figure to roughly 60,000 to 70,000 miles, and that owners were not always notified. Repairs described include cylinder head replacement. Mostly reported between about 54,000 and 85,000 miles, with several failures near or past the revised replacement interval.

   2 related service bulletins

   What to check: Ask for documentation of the last timing belt and tensioner replacement and its mileage; without a record, treat the belt as due and price the job into the purchase.

   “(1) events leading up to the failure of my timing belt were normal driving conditions, ie no sounds, smells, or visual damage. (2) on 01/15/2007, my timing belt broke while driving. The consequences are damage to the cylinder head, as well as other parts of the engine. (3) last year, Audi changed the time/mileage needed in order to change timing belt from 106,000(as stated in the owner manual, of the Audi TT) to 60,000-70,000, according to an employee, I spoke with. …”

   NHTSA complaint #10186435, filed 2007-03, 85,000 miles

   “Purchased a 2001 Audi TT 225 coupe on october 2000, eight years later and only 69700 miles,timing belt fails causing major damage to the engine. August 2008 Audi sent out a letter acknowledging a potential problem with the timing belt but since it was not a recall I paid only a small attention to it. Besides all this clearly the design of the timing belt is faulty or inadequate to be used on a sports car!!!”

   Brakes

   Brake and ABS/ESP problems

   • 7 complaints (6%)
   • median 75,500 mi at 9.0 yrs old (6 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2003–2024

   Complaints describe brakes that would not engage, sometimes requiring the emergency brake to stop, and dealers attributing it to a vacuum line; one owner says a dealer found nothing wrong. Others report the ABS and ESP warning lights coming on, with a lateral sensor replaced but the lights returning, and one owner reports the ABS module failing near 80,000 miles with a large repair quote. Reported from about 50,000 to 100,000 miles.

   1 related service bulletin

   What to check: Confirm the ABS and ESP lamps go out after start-up, test the brakes firmly at low speed, and ask whether the ABS module or vacuum lines have been serviced.

   “The brakes failed on the 2001 Audi TT sportscar. The first time the car crashed. The Audi dealer said there was nothing wrong with the brakes. A few months later the brakes failed again, and fortunately the car did not crash. Again, Audi insists the brakes are fine, but obviously, something is seriously wrong. I am afraid to drive the car.”

   NHTSA complaint #10345136, filed 2010-07, 83,000 miles

   “2001 Audi TT 1.8 quattro ABS module. Poor pump and ABS fails around 80k miles. Huge repair price and many complaints. I feel as though they did a really poor job at putting this module together.”
