Additional notes
- 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.
- Opel Astra diesel (491+ listings at 150k+, avg 225k km, €3.8k). At this mileage 1.6 CDTi timing chain is stretched (€1200-2000 to replace), 2.0 CDTi has better chain but injectors and turbo are worn. Many ex-fleet from Germany/France with highway miles — check if DMF has been replaced.
