2001 Audi TT Repair Log Felix Wong

Logbook entries for the ’01 Audi TT Roadster Quattro.


  • November 13, 2008 (Thu): Dealer Forest Faulknor had Bo’s Imports of Hayward, CA replace the water pump, timing belt, and engine coolant. Receipt shows cost for this was $380 for labor and $170 for parts. Mileage: 67,832.


  • January 2, 2009 (Fri): Took possession of the Audi TT Roadster Quattro in San Jose. Windshield reservoir warning icon was on so filled that with some windshield washer fluid acquired at Kragen in San Jose. Successfully used onboard GPS unit to get to Tori’s. Mileage at possession: 68,350.
  • January 3-4, 2009 (Sat-Sun): Drive home from CA to Fort Collins, stopping in Salt Lake City overnight. Only glitch is that the windshield fluid froze (rated to only 32 degrees) as it got as cold as -18F outside. Considering how quickly I ran out of fluid I suspect some sort of leak.
  • February 23, 2009 (Mon): Successful created and loaded NAV-TEQ C-Navi CD #2 (with info for midwestern states including CO) from image files sent by Alexander.
  • February 25, 2009 (Wed): Teeter is properly registered in CO with Elaina’s RCKNSOL plates. Previously had to get temporary license due to waiting for Forrest Faulkner needing to send a notarized Statement of Fact to clear up confusion on title. Mileage: ~70,600.
  • September 30, 2009 (Wed): Replaced hazard light switch part number 8N0-941-509-B (with the old one, part number 8N0-941-509-A, turn signals started working only intermittently and erratically). Followed Audi TT hazard light switch replacement instructions. Mileage: 73,288.
  • October 1, 2009 (Thu): Checked for leak in windshield washer reservoir, which entailed removing the front left side wheel well cover. Conclusion: no leak. Topped off reservoir with 1 gallon of Prestone De-Icer -34deg windshield washer fluid. Mileage: 73288.
  • October 1, 2009 (Thu): Synthetic oil change at Grease Monkey. Used Mobil 1 5W30. $57.93. Mileage: 73,292.
  • October 2, 2009 (Fri): Fixed glove box handle so that it would be more flush. Required filing/grinding of plastic tab behind handle, and also some enlarging (grinding with Dremel) of the hole that the glove box latch “plunger” inserted into upon closing. Mileage: 73,296.
  • October 6, 2009 (Tue): Brake fluid flush and tire rotation by Just Brakes. $53.76. Just brakes recommended 1) replacement of rear shocks since some cupping on inside of rear tires evident; 2) replacement of strut bushings up front—they say the bushings are compressed as evidence by top of struts protruding out from top of towers a little; 3) strut replacement (not critical yet) since probably approaching end of their life. Mileage: 73,423.
  • October 6, 2009 (Tue): Plugged tire punctures (two) caused by nails in right front tire (was right rear tire before tire rotation). Location of both plugs are in grooves in tread (not sidewall) roughly aligning between the ‘S’ and ‘4’ in ‘PROXES4’ lettering on sidewall. Mileage: 73,335.

  • May 18, 2010 (Tue): Due to low-gas condition, car misfired on startup and check engine light went on. Since no misfiring occurred after, the check engine light went off after exactly three drive cycles.

  • May 19, 2010 (Wed): A/C servicing by Fort Collins Foreign Car Service. They needed to replace the high pressure switch in addition to adding 134a Freon and A/C oil with dye. Mileage: 78,196.

  • June 20, 2010 (Sun): Check engine light went on while driving with Leah to Berthoud to look at a Hyundai for her. Ordered a code checker from Asia a few days later. Mileage: ~78,900.
  • July 13, 2010 (Tue): Replaced key fob batteries (quantity 2 of size CR1620). Activated key fob by sticking key in door, turning it and then pressing a button on the fob. Now can lock or unlock the doors from 40 feet away instead of 3. Mileage: 79,120.
  • July 19, 2010 (Mon): Checked and cleared engine codes. Three error codes were present: 17536 (Long term fuel trim-system too lean – Bank 1); 17521 (Bank 1 heated oxygen sensor internal resistance too high); 17536 (again).

  • March 28, 2011 (Mon): Replaced the spark plugs with NGK BKR6E V-groove resistor type plugs gapped at .032″. Former plugs were NGK PFR6Q; they were all remarkably clean when I pulled them and seemed to be gapped at .030″. Mileage: 82,410.

When I pulled the NGK spark plugs from the Audi TT Quattro as part of its 80,000-mile service, the insulators and electrodes looked remarkably clean.

  • April 20, 2011 (Wed): Had Fort Collins Foreign Car Service replace the rear differential Haldex fluid and filter and serpentine belt as the final part of the Audi’s 80,000-mile service. The shop also diagnosed the source of the washer fluid leak—left headlight washer has a busted check valve that would need to be replaced. Mileage: 82,742.
  • April 21, 2011 (Thu): Had Manhattan Auto Spa do a complete interior and exterior detailing using a Living Social $64 voucher. Also paid $50 extra to try to buff out the long scratch on the right-side door and hood that were on the car when I bought it. The scratches could not be eliminated but now look less noticeable. Mileage: 82,757.
  • October 29, 2011 (Sat): Check engine light went on. Engine code: 17536 (Long term fuel trim-system too lean – Bank 1). Maybe the Mass Flow Sensor needs to be cleaned again? Mileage: <85,000.

Old battery was the same model (albeit not with a green top), but went dead after 65 months (was from November 2006). Pro-rata warranty only saved $0.20. When disconnected battery, one-touch convenience of windows was not working, but followed instructions in owner’s manual to get them to work (raise windows all the way up, then hold window switch up for 1 second). Mileage: 87,606.

  • July 28, 2014 (Mon): Brought battery into Interstate Battery for testing, since three times already I was caught without power upon startup. (At least one of those times was due to leaving interior light on, but the other one or two times was after not driving for a week or more.) Interstate said the battery was fine and just needed to be charged more, like overnight at low amperage.
  • September 4, 2014 (Thu): Installed Battery Brain (Bronze edition) which will automatically disconnect battery if voltage drops below 11.8V for 30 seconds. Successfully tested by leaving lights and radio on with car off, and the Battery Brain disconnected the battery after less than a minute. Mileage: 98,888.
