Additional notes
- Audi A8 diesel (890+ listings in BG). Air suspension failure is almost guaranteed at 10+ years. Combined with timing chain, AdBlue, MMI electronics, and luxury car labor rates, total cost of ownership is very high.
- 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.
- Audi Q7 diesel (245+121 listings, avg 170-176k km, €35k) — full-size SUV with full-size bills. EA897 3.0 TDI timing chain service due (€3000-5000), air suspension compressor and bags wear at this mileage (€4000+), AdBlue system failures (heater, injector, tank). Brake discs alone are €600-800/axle.
- A7 diesel (225 listings, avg 152k km, €34k) — sleek sportback hides expensive maintenance. EA897/EA898 V6 diesel timing chain at front (expensive labor), DL501 S-Tronic 7-speed mechatronic issues, adaptive air suspension (if equipped). LED matrix headlights €2000+/unit to replace.
