Common Audi A4 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.
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 |
|---|---|---|---|
| 2.0 Diesel | ~280k km | ~€270 | 322 |
| 2.0 Petrol | ~300k km | ~€570 | 34 |
| 1.4 Petrol | ~300k km | ~€280 | 22 |
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.
