AI Market Summary

Diesel 8 Series offers strong performance and prestige at €65k–€70k; however, reliability score of 3 (out of 5) signals meaningful ownership risks ahead.
DPF regeneration problems are common on this generation, worsened by short urban trips — confirm full service history and recent DPF cleaning before purchase.
Dual-turbo boost sensors fail prematurely; check for any limp-mode warning lights or power loss during test drive, and budget for potential €800–€1,200 repair.
ZF 8-speed transmission hesitation in city traffic is known — take extended test drive in stop-start conditions to assess shift smoothness and responsiveness.
NI import saves €5,049 before VRT; factor in full VRT and NOx levy (roughly €3,500–€4,500 extra) — true saving is marginal and erodes quickly with repairs.

€350/yr

Diesel fuel filter replacementEvery 2 years or 40,000 km; essential to prevent injector fouling
