All Known Issues

Oil Dilution (Diesel)

SeriousEngine

Interrupted DPF regenerations cause unburnt fuel to leak into the oil sump, raising the oil level and thinning the lubricant.

Est. Repair Cost: £150–£300 (Oil change & forced regen)
Warning Signs:

Oil level above the "X" mark on dipstick, Check engine light, Reduced engine performance

What to Inspect:
  • Check the dipstick for an "X" mark above the Max line
  • Verify frequency of long-distance trips

DPF Clogging (1.8 DI-D)

ModerateEngine

The diesel particulate filter clogs quickly if the car isn't driven on the motorway regularly.

Est. Repair Cost: £500–£1,200
Warning Signs:

DPF warning light, Rising oil level, Poor fuel economy

What to Inspect:
  • Check the oil level; if it's high, it suggests aborted DPF regens

Buying Tips for 2013 Mitsubishi ASX

  • Test the 6-speed torque-converter automatic on the 2.2 DI-D for smooth upshifts and check transmission fluid service history
  • Ensure the air conditioning blows cold, as the front condenser is vulnerable to stone-chip puncture
  • Check rear brake calipers and discs for binding or overheating after an extended test drive
  • Verify that the DPF warning light illuminates during ignition check and extinguishes once running
