Additional notes
- Opel 2.0 CDTi (A20DTH) 160/163 hp timing chain stretches after 80k km. Chain at rear of engine = expensive repair (€1,500-3,000). Listen for chain rattle on cold start. Early models (2009-2012) worst affected.
- Opel Astra diesel very common in Bulgaria (1100+ listings). City-only driving clogs DPF quickly. EGR valve carbon buildup and turbo actuator failure are frequent issues at 100k+ km.
- Diesel car from before 2018 with very low mileage suggests city-only use — DPF is likely clogged or has been removed (illegal). Check DPF status and EGR condition.
- Insignia diesel auto (160 listings, avg 216k km, €7k) — 2.0 CDTi (A20DTH) has known timing chain stretch issues beyond 150k km. Automatic is usually Aisin TF-80SC which needs fluid change at 60k (almost never done in BG). At 200k+: chain, tensioner, and guide replacement is €1500-2500.
