Selected complaints filed with NHTSA by 2001 Audi TT owners, lightly cleaned up (personal details are redacted by NHTSA).
On our Audi TT 2001 convertible, the electrical outlets underneath the dashboard caught on fire. The fire department was called and after an investigation, found no known cause of fire. Also, prior to this fire, the tip of the spark plug fell into the engine cylinder block, causing us the owners to pay in full for a new engine head to be replaced....lots of money (approximately $8000). We replaced it through a well known professional Audi shop auto haus munich in san diego. Hazardous lights needed to be replaced professionally because it interfered with the signal lights. Much money & time spent, and many headaches experienced while owning this beautiful yet troublesome car.
Headlights just stopped working again for the umpteenth time. Park light and high beams work fine. This is a reoccurring problem with the low beams. Can be driving along fine and cut car off and start back up and low beams just won't come on. If it was 1 at a time I could see it as being no problem but they both stop working at the same time. Keep replacing switch and headlights...thinking this would alleviate problem to no avail. See this is an ongoing problem with Audi owners. Also see that it's a recall on the newer models but not the late models.
Electrical issue with gauge cluster, fuel gauge inaccurate (runs out of gas in middle of hwy), low oil pressure light comes on (manual says to stop immediately when light comes on), air bag light comes on! Everything I have read states these are all problems with the gauge cluster (cost over $1000 to have replaced!) Audi USA knows about problem but refuses to do anything about it. Audi has a recall in the uk for this problem, why not here in the U.S. ?? This is a serious safety issue!
I have a faulty instrument cluster on my Audi TT 2001 roaster. This part controls the tachometer, odometer, speedometer, fuel gauge, temperature gauge and all the warning lights for oil pressure, coolant levels, etc. This is one of the most important parts for the safety of the vehicle. This is the second instrument cluster that has had to be replaced in the vehicle. The initial cluster was faulty and displayed inaccurate gas gauge readings, it was replaced in 2002/3. My current instrument cluster is displaying inaccurate temperature readings. I have reviewed information on websites (edmunds care space at edmunds.com; Audi TT car club at audittcca.com, etc.), and understand that this is a very common problem. Audi uk recalled this component on the 2001 Audi TT and have agreed to cover all previous costs of repair. …
Check engine light is on, power door lock button sometimes does not work, driver side window sometimes does not fully close, button to put the convertible top down sometimes does not work, button for motion sensor alarm does not light up when pressed, lcd display turns fully red and next day is back to normal, rear defrost lines not fully operable, water leaks in between window and door seal on both doors. I have just purchased my car with about 19000 miles, a few days later the check engine light turned on. Took it to Toyota grossinger dealer and said that it was the fuel gage and that I should wait a few months for it to turn itself off. I called Audi dealership and said that my car had no recalls. Then, I went to a mechanic and said that computer showed that solenoid sensors had failed, so it was replaced. …
My car has had a low oil pressure light coming on for the last three months, and it's occurring with more frequency. The light only comes on when I take my car out of gear and put it in neutral while slowing down or while waiting at a stop light. After taking it to three different Audi dealers, I have had multiple answers as to the problem. Several hundred dollars later, my light still comes on and nothing has been fixed. Even more recently and just to top it off, my instrument panel cluster has blown. So far, it's just the temperature gauge, fuel gauge, LED display, and a warning light that triggers one of my headlights to turn off, but from what I've read online, the speedometer is soon to follow. There has been a recall in the uk for this, but Audi USA won't do anything about it. …
2001 Audi TT convertible: the horn just stopped working one day, the instrument cluster display started to not display clearly then the car seem to lack power when starts up, car then would not start in the mornings, then the car would not start after being left for more than 20 minutes, and the car would often totally shut off while stopped at a red light then automatically turn back on again all by itself. The brake lights also stayed on at all times even when the car was completely shut off. Ignition coils also caught on fire after check engine light was on for only a few hours. The convertible top warning light is flashing on the instrument cluster, and there is a rattling noise coming from the convertible top latch area while driving. Consequences: dangerous life threatening situations, fear, stress, financial burden/hardship, time consuming, and extreme inconvenience. …
Tl contact owns a 2001 Audi TT quattro. While driving between 25-30 MPH, the contact received four citations on March 19, 2008. The citations stated that she was driving 45 MPH in a 35 MPH zone and 51 MPH in a 35 MPH zone. The citations were received within ten minutes of one another. The contact also noticed that the fuel gauge indicator displayed 1/4 tank; however, the vehicle was out of fuel a few miles later. She received a class action letter indicating that the speedometer and fuel gauge were not operating normally and could display inaccurate readings. The dealer and manufacturer stated that the class action suit does not apply to the vehicle since it is beyond the seven year period. The approximate failure mileage was 5,000 and approximate current mileage was 100,000. Updated 6/2/08 updated 05/30/08
Car shows 1/4 of fuel in tank when tank is completely empty causing me to run out of gas multiple times in hazardous situations. I can not read the lcd screen so I can not see any warning lights (gas, oil change, trunk open, etc). My instrument cluster tells me that my vehicle is constantly overheating, which is false. Sometimes when I turn my lights on the dashboard will not light up, nor will it register my rpms or even my speed. If I can not read my speed or even see if I have gas, then I am not safe driving this vehicle. The cluster has now failed completely, which prevented my car from even starting so I had to get it towed to the dealership. Further more, Audi has refused to fully pay for this item to be replaced even though it has been recalled! Outrageous.
