Audi TT and TTS 8S buying guide
The third and last TT was built from 2014 to 2023 as a coupé and roadster, with 1.8 and 2.0 TFSI petrol engines, a 2.0 TDI diesel until 2018, and the 306PS TTS. The engines have a good record, and the checks are mostly well-known wear points.
The versions
- 1.8 TFSI (180PS, front-wheel drive) and 2.0 TFSI (230PS, front-wheel drive or quattro) until the 2018 facelift
- After the facelift: 40 TFSI (197PS) and 45 TFSI quattro (245PS)
- TTS: 2.0 TFSI (EA888) with quattro and Magnetic Ride adaptive suspension as standard, 306PS, 320PS from 2021
- 2.0 TDI diesel (184PS, engine code CUPA) until 2018
- 6-speed manual or S tronic dual-clutch automatic (most cars); quattro is Haldex-based
- Coupé and roadster bodies (the TT RS has its own page)
What to check on a 8S TT
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
Coolant loss on the 2.0 TFSI
What to look for: With the engine cold, check the coolant level in the expansion tank, and ask whether it has needed topping up. With a torch, look around the engine for dried coolant deposits or dampness.
Why it matters: Low or falling coolant on the 2.0 TFSI is often a cracked plastic thermostat housing, a common fault on this engine family. Radiators are also starting to fail at this age. A housing that's been replaced is one less job to come.
Front suspension rattles
What to look for: Drive slowly over speed humps and broken road with the radio off, and listen for rattles or knocks from the front. Notice whether the car feels slack or vague over bumps.
Why it matters: Rattles after around 50,000 to 60,000 miles usually mean worn front wishbones, ball joints or anti-roll bar parts. They're routine replacements, and new parts in the invoices are a good sign on a higher-mileage car.
quattro and S tronic servicing
What to look for: On a quattro car, look in the history for Haldex oil changes. On an S tronic, look for gearbox oil and filter changes. On the drive, pull away gently several times and feel for jerks.
Why it matters: The quattro system is Haldex-based and needs servicing every three years. Specialists stress keeping the fluids fresh in both the gearbox and the four-wheel-drive system, so records of both are a sign of a car that's been looked after.
