Problematic

Reliability, common problems and owner reviews for the Ford Focus II 1.6 TDCi (DV6). Check this before you buy used.

The PSA-derived 1.6 diesel with a notorious failure chain: degraded copper injector washers let exhaust gases carbonise the oil, which blocks the fine gauze in the turbo oil-feed banjo, starving the turbo of oil until the bearings fail. Add DPF clogging on short trips. Only sensible with documented turbo-feed/injector-seal maintenance and motorway use.

Same engine, other cars

This is the same physical engine (DV6) sold under different names across brands. Reliability is broadly shared — cross-check these:

Known Issues

Injector seal → turbo oil starvationcritical

Copper injector washers degrade → carbon in oil → blocked turbo oil-feed gauze → oil pressure to turbo drops (to ~0.8 bar) → turbo bearing failure.

Fix / Workaround: Replace injector seals; clean/replace the turbo oil-feed banjo + gauze; strict oil changes. Verify done.

Repair cost: €300–€1200

Typically appears after: 100,000 km

Turbo failurecritical

Turbo fails (loss of power, blue smoke, whine) — often a consequence of the oil-feed issue.

Fix / Workaround: Replace turbo (~£800) AND fix the oil-feed cause.

Repair cost: €600–€1200

Typically appears after: 120,000 km

DPF cloggingrecurring

DPF blocks on short trips.

Fix / Workaround: Motorway runs; clean/replace.

Repair cost: €300–€1000

Mileage Thresholds

After 100,000 km: Injector-seal/turbo-feed failure chain risk.

Pre-Purchase Checklist

  • Ask about injector seal + turbo oil-feed banjo service
  • Buy only if motorway-used with clean oil history
  • Check for turbo whine / blue smoke
  • Prefer the 2.0 TDCi
