AI Market Summary

Smooth, efficient diesel engine with strong mid-range torque and typically 35+ mpg real-world. Premium interior and robust build quality expected at this price.
Well-priced relative to rivals; +17% year-on-year suggests steady demand. Median mileage at 171k km sits comfortably within normal range for an 8-year-old.
DPF regeneration faults common on urban or low-mileage examples; VGT turbo sticking and EGR carbon buildup are known weak points. Budget €800–€2,500 for DPF cleaning or replacement if limp mode occurs.
Before purchase, request full service history and ask seller if DPF or turbo work has been done. Have a pre-buy diagnostic scan to check for stored fault codes, especially P0400s (EGR) and boost-pressure faults.
Three recalls on file—confirm all have been completed with an Audi dealer or check your VIN on the NHTSA/EU recall database before committing.
