Reliability, common problems and owner reviews for the Honda Accord 2.2 i-DTEC (N22B). Check this before you buy used.
Capable of 300,000+ km with the right care, but the cost risk is the emissions/ancillary set: the DPF sits right after the turbo and clogs on short trips (forced regen €150–250), the EGR pipe cracks, the DMF and HP pump wear, and — critically — it MUST run 0W-30 low-SAPS oil (dealers historically filled wrong 5W-30, damaging DPF/turbo). The 180hp Type-S clutch is weak. A 2011+ car with correct-oil history and EGR pipe done is the sweet spot.

Year Cutoffs
Mileage Thresholds
After 120,000 km: DPF/EGR/clutch attention.
