Reliability, common problems and owner reviews for the Honda CR-V 2.2 i-CTDi / i-DTEC (N22 diesel). Check this before you buy used.

The 2.2 diesel is torquey and well-suited to the CR-V. The earlier i-CTDi (N22A) is the tougher, simpler unit and well regarded; the later i-DTEC (N22B) adds a DPF and is more sensitive to short-trip use (DPF clogging, and some examples saw oil dilution from interrupted regens). Both want clean oil and attention to EGR. A motorway-driven, documented car is dependable; a short-trip i-DTEC needs careful DPF/oil checks.

Same engine, other cars

This is the same physical engine (N22A) sold under different names across brands. Reliability is broadly shared — cross-check these:

Known Issues

DPF clogging / oil dilution (i-DTEC)recurring

i-DTEC DPF clogs on short trips; interrupted regens can dilute oil with fuel.

Fix / Workaround: Motorway regens; check oil level/dilution; correct oil.

Repair cost: €300–€1200

Typically appears after: 120,000 km

EGR / injectorsrecurring

EGR sooting and injector wear with age.

Fix / Workaround: Clean EGR; injector test.

Repair cost: €200–€900

Typically appears after: 150,000 km

Year Cutoffs

2010: Before — i-CTDi — simpler, no DPF, very well regarded. After — i-DTEC — DPF added; more short-trip-sensitive.

Mileage Thresholds

After 180,000 km: DPF/EGR attention (i-DTEC).

Pre-Purchase Checklist

  • ☐i-CTDi is the tougher diesel
  • ☐i-DTEC: DPF + oil-dilution checks
  • ☐Motorway use suits it
