Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 40,000 mi; coolant every 10,000 mi. The big-interval services (every 10,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2002 Audi TT/TTS Coupe/Roadster dominate in one area — the electrical system, 14 of 38 reports (37%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the electrical system, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 1 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the electrical system pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
