Common Audi A6 problems
Known weak spots to check before you buy, with typical Irish garage costs if the problem is there.
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.
Automatic gearbox health · €300–€2,500
Make sure the gear changes are smooth when warm, check for a gearbox warning light and ask if the gearbox oil was ever changed.
Engines and how long they last
| Engine | Usually lasts | Motor tax / year | For sale |
|---|---|---|---|
| 2.0 Diesel | ~350k km | ~€270 | 478 |
| 2.0 Hybrid | ~300k km | ~€270 | 106 |
| 3.0 Diesel | ~320k km | ~€750 | 18 |
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
