2001 Audi TT/TTS Coupe/Roadster

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 TT/TTS Coupe/Roadster.

Body PASSENGER CARTransmission Manual 5-spd

The 2001 Audi TT and TTS pair Coupe and Roadster bodywork with a five-speed manual transmission, returning 20 city / 29 highway / 23 combined mpg under EPA testing while drawing on a 4.8-quart oil capacity rated for 5W-30 or 5W-40 API viscosity. The model year registers 132 owner complaints weighted toward the electrical system, joined by a recall count of five that establishes it as a heavily-documented entry in the TT's reliability record. For researchers, that profile means electrical faults should be treated as the baseline expectation rather than a peripheral issue, and the breadth of recalls signals that Audi was simultaneously addressing a meaningful share of factory-identified defects that had not yet surfaced as consumer complaints.

From the factory this vehicle uses a BCI 45 · N/A CCA battery, OE oil filter 06A115561B. Note the factory front wiper blades and serpentine belt are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter at 5,000 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 2001 Audi TT/TTS Coupe/Roadster dominate in one area — the electrical system, 59 of 132 reports (45%), well ahead of the next concern. None of this vehicle's 5 recall campaigns target the electrical system, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 4 of the reports describe a crash and 3 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.
