Common issues with the Audi A3
- 2.0 TDI (CBBB) timing chain failure — rattle on cold start is a serious warning sign; check service history for tensioner replacement
- DSG gearbox mechatronic unit failure (DQ200 7-speed dry-clutch) — jerky low-speed behaviour
- Carbon build-up on direct-injection 1.4 and 1.8 TFSI inlet valves — causes rough idle and misfires
Negotiation tips
- Prefer the 2.0 TDI 150 (CRLB/CRBC) engine over earlier TDIs for timing chain reliability
- Virtual Cockpit adds real resale value on 8V (2012–2020) — worth prioritising
- Audi MMI updates can cost £300 at a dealer; check if the latest maps are installed
