2.2 CRDi DPF Clogging & Oil Dilution from Short Journeys

ModerateExhaust & Emissions

When used predominantly for short urban school runs, the 2.2 CRDi diesel struggles to complete active DPF regenerations, leading to rising sump oil levels (fuel dilution) and DPF blockages.

Est. Repair Cost: £300–£1,100
Warning Signs:

Oil level rising above MAX mark on dipstick, DPF soot warning light on cluster, Frequent radiator cooling fan running after engine shutdown

What to Inspect:
  • Pull the oil dipstick and smell for diesel odor
  • Ask about typical driving routes and motorway usage
  • Check for DPF regeneration history

Rear Suspension Bush & Self-Levelling Damper Failure

ModerateSuspension & Chassis

Heavily loaded or towing vehicles suffer accelerated wear to rear trailing arm bushes and self-levelling rear shock absorbers, causing rear-end sagging and bouncing.

Est. Repair Cost: £350–£800
Warning Signs:

Rear bumper sits noticeably low when parked, Metallic thumping over speed humps, Uneven inner rear tyre shoulder wear

What to Inspect:
  • Inspect rear shock absorbers for oily dampness
  • Check for trailing arm bush advisories on MOT history
