A manual Mk2 Audi TT (2006 to 2014) is the pick, though a 2008 to 2013 2.0 TFSI needs a rattle-free cold start; skip the seven-speed dry-clutch S tronic, which carries a known mechatronic fault.
3 known faults, 2 rated high severity in our database; owners report 36.8 mpg, 87% of the official figure. Everything below is built from that data and the archived owner history, not from a press car.

The seven-speed dry-clutch S tronic (DQ200), which the TT only has with the 1.8 TFSI, has a known fault where its mechatronic unit fails, covering 2008 to 2019 and showing up between 30,000 and 80,000 miles, and EA888 2.0 TFSI cars from 2008 to 2013 can have a timing chain tensioner fail, which starts as a rattle on a cold start.
The Mk1 (1998 to 2006) is the riskier buy because its 1.8 turbo, the engine in most of them, has a known oil sludge fault that blocks the oil pump pickup and starves the engine between 70,000 and 110,000 miles. If you still want one, don't touch it without paperwork showing regular oil changes, and find out whether it's front-drive or quattro, as plenty were grey imports.
Cars from 2014 onwards have far fewer items on record, so treat them as unproven rather than sorted. Two cars on record let water into the tailgate or boot, two had frameless windows or doors that wouldn't shut properly in sub-zero weather, and one owner of a 2015 2.0 TFSI had the clutch fail at low mileage. If one has the seven-speed dry-clutch S tronic, the same mechatronic fault applies.
A manual gearbox is the safest choice on any TT, because the twin-clutch automatics carry the gearbox problems on record. The seven-speed dry-clutch S tronic (DQ200), found only on the 1.8 TFSI S tronic, has a known mechatronic fault that brings a pause when pulling away, a lurch of power after it and jerky changes. The six-speed wet-clutch version needs its oil and filter changed every 40,000 miles or 48 months, so ask for the receipts.
On the Mk1, the 1.8 20-valve turbo carries the oil sludge fault, and a red oil pressure light, ticking hydraulic lifters or a failed turbo are the signs. Its air mass sensors give trouble too, and cars built between 2001 and 2002 had ignition coils fail. The 3.2 VR6 came with the early DSG, whose heat exchanger can let coolant into the gearbox fluid and finish the transmission.
On the Mk2, the EA113 2.0 TFSI has a known fault where the fuel pump's cam follower wears through between 40,000 and 80,000 miles, so watch for power dropping away under hard acceleration and a ticking noise from the cylinder head. The EA888 engines have a timing chain tensioner that can fail on 2008 to 2013 cars, and if it's ignored the chain skips teeth and the engine needs rebuilding.
Quattro cars use a Haldex coupling whose oil is due every 30,000 miles or three years, though specialists advise 20,000 miles and a clean of the pump strainer. Mk2 owners have reported Haldex and rear diff failures, and one paid £1,478 for a new Haldex clutch and diff on a 2011 2.0 TDI quattro at 65,000 miles.
Pull an S tronic car away from a standstill several times: a hesitation followed by a surge, or juddering changes, point to the mechatronic unit or clutch pack. On a quattro, listen for any odd noise when leaving junctions, because one TTS owner heard a faint one there shortly before the rear diff's pinion bearing failed on the motorway.
Start the engine from cold yourself and listen for a rattle on an EA888 2.0 TFSI or 1.8 TFSI, since that's the chain tensioner giving warning. On a Mk1 1.8 turbo, watch for the red oil pressure light and ticking lifters. Check every gauge works and the mileage readout isn't fading, as Mk1 dashpods fail and one owner's 2012 Mk2 cluster died completely.
Hunt for water: wet carpets, a damp smell or a soaked rear seat. The Mk2 coupé's hatch lets rain in when it's opened wet, one Mk1 Roadster owner chasing sodden footwells got nowhere with new seals and turned to the blocked drainage channels, and a fuel smell in a Mk1's boot points to a split plastic tank. On any Roadster, put the roof up and look hard at the fabric where it folds.
Ask for receipts for Haldex oil changes, S tronic oil and filter changes and regular engine oil changes, and on a Mk1 ask for proof the recall work was done. With a grey import, confirm whether it's front-drive or quattro before agreeing a price. An intermittent ESP light isn't always serious: one Mk2 owner cured theirs by paying £20 for a new brake pedal switch.

Only if the history shows frequent oil changes, because the 1.8 20-valve turbo in most Mk1s carries a known sludge fault that blocks the oil pump pickup between 70,000 and 110,000 miles and can take the turbo with it. There's a 3.2 VR6 from 2003 too, but it came with the early DSG, which has its own problems on record.
Age brings a string of smaller faults. Air mass sensors fail on the 1.8 turbo, cars built between 2001 and 2002 had ignition coils give up, and dashpods fail on older cars. The plastic fuel tank can split along its seams, and the front anti-roll bar's plastic collars trap corrosion underneath until it splits and the whole bar needs replacing.
On the 3.2 DSG, early heat exchangers had started failing by 2009, letting engine coolant mix with the gearbox fluid, which can wreck the transmission. A delay pulling away followed by a surge points to the mechatronic unit. One owner's 2003 3.2 DSG lost power with the EPC light on, and the cause turned out to be a faulty brake light switch.
On a Roadster, the fabric roof wears where it folds, and a bag or bottle sitting on the shelf behind the seats can smash the glass rear screen as the roof lowers. The first official UK cars were recalled in 2000 to have ESP and a rear spoiler fitted, a 2001 recall covered cars up to 2000 whose rear hub carrier ball joints could corrode and seize, and a 2002 recall replaced airbags on some cars with three-spoke steering wheels.

Yes, in manual form it's the TT to buy, though a 2008 to 2013 EA888 engine needs a clean cold start with no chain rattle, and any seven-speed dry-clutch S tronic carries a known mechatronic fault from 30,000 to 80,000 miles. Some 2.0 TFSI cars have the EA113 engine instead, whose fuel pump cam follower fault shows as power loss and a ticking top end.
Twin-clutch failures turn up in owner reports too. Among a string of faults over 69,000 miles, one owner's 2007 2.0 TFSI S tronic needed a new gearbox, another's 2007 3.2 lost every gear except first and third, and a 2012 1.8 S tronic developed a worsening judder at around 20,000 miles. One owner of a 2010 1.8 TSI Roadster also found it went from full to the oil warning light in 500 miles.
The TTS has more on record. One report puts TTS clutch life as low as 20,000 miles, one owner found pitted camshaft lobes at around 41,000 miles, another had a head gasket fail, and Haldex trouble crops up: one TTS coupling failed because its filter had blocked despite regular fluid changes, and another's rear diff failed just after a Haldex fluid change.
Around the body, the coupé's rear hatch lets water pour onto the back seat if it's opened in the rain, two owners had window regulators fail in both doors, and steering racks or columns can rattle and whine. If the engine cuts out and the hazards come on, a faulty airbag switch can be telling the ECU the car's crashed. One 2012 car's exhaust had to be replaced at 30,000 miles, and its owner paid £650.

The original UK Mk1s all had four-wheel drive, and the 225 quattro feels planted and properly entertaining on a tight, twisting road. The TT Sport quattro from 2005 is the sharpest of the lot to drive, having shed its back seat and spare wheel to save weight and make it quicker still.
