AI Market Summary

Diesel efficiency and refinement remain strong; 91k km is mid-range for age. Prices up 15% year-on-year, so demand is solid but stock is tight (4 active listings).
DPF regeneration blockages are the main headache on this generation—budget €800–€1,500 for professional cleaning or replacement. Confirm service history shows regular motorway driving and DPF maintenance checks.
AdBlue heater failures (€400–€600) and injector carbon buildup are secondary diesel-specific risks. Request full service records and ask seller whether DPF or AdBlue issues have already been addressed.
Before purchase, have a diesel specialist perform a pre-buy inspection focusing on DPF condition (check for warning lights, limp-mode history) and request proof of recent AdBlue top-ups and system checks.
Well-positioned in market at median €44k, but DPF repair costs and tight supply mean prices remain firm—not a bargain, but fair for a 6-year-old with moderate mileage.

Diesel-specific servicing (DPF, AdBlue, EGR monitoring) is essential; avoid short urban drives without regular motorway running to prevent DPF clogging. Budget for potential DPF cleaning or injector service every 40,000–60,000 miles.
