Our take on the Audi TT
A 2018 Audi TT typically advertises at €22,950 and a 2013 one at €13,950, so it loses roughly 9% of its value a year at that age. Most for sale are petrols; diesels are rarer, at 16%. At the NCT, the 2004–2017 cars do better than other cars the same year. The 1.8 petrol is the most common engine (49% of those with a known engine), and it usually lasts around 300k km.

Common Audi TT problems
Known weak spots to check before you buy, with typical Irish garage costs if the problem is there.
DSG gearbox mechatronic / clutch (7-speed) · €900–€2,200
In slow traffic and reversing, watch for jerks, clunks or a slipping feeling. A flashing gear display means it's in limp mode.
Oil pump drive / cracked cylinder head (2.0 TDI PD) · €800–€2,500
Ask for proof of oil pump/balance-shaft work. Check the oil pressure light goes out instantly on start, and look for coolant loss or white smoke.
Heavy oil use (1.8/2.0 TFSI) · €300–€2,500
Ask how often it needs topping up. Check the dipstick and look for blue smoke on hard acceleration.
Rust on sills, arches and brake pipes (15+ years old) · €100–€600
Kneel down and look at the sills, rear arches and the brake pipes under the car. Flaking rust is an NCT fail.
EGR / DPF blocking (1.6/2.0 TDI) · €300–€900
Ask how it's driven: short trips clog the DPF. Any DPF/engine light, limp mode, or heavy smoke when revved is a warning.
Timing belt history · €350–€700
Ask when the timing belt and water pump were last done (usually every 160,000 km or 5–6 years). No proof = budget for it.
Engines and how long they last
| Engine | Usually lasts | Motor tax / year | For sale |
|---|---|---|---|
| 1.8 Petrol | ~300k km | ~€600 | 22 |
| 2.0 Petrol | ~220k km | ~€600 | 15 |
| 2.0 Diesel | ~280k km | ~€270 | 8 |
2.0 Petrol: usual problem: heavy oil use and timing chain.
2.0 Diesel: usual problem: oil pump drive and cracked heads.
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
