All Known Issues

1.6 THP timing-chain stretch and carbon build-up

SeriousEngine

The turbo petrol shares the usual Prince-engine faults: cold-start chain rattle, cam timing issues and carboned-up intake valves that can make a tidy C4 expensive very quickly.

Est. Repair Cost: £500–£1,800
Warning Signs:

Rattle on cold start, Engine-management light, Misfire or hesitation, Poor idle quality

What to Inspect:
  • Start it from stone cold
  • Look for chain-kit invoices
  • Check whether oil changes were annual rather than stretched

EGS / ETG gearbox hesitation and clutch wear

ModerateGearbox & Transmission

The automated manual gearbox is slow by design, but excessive jerking, slipping or failure to select gears usually means actuator or clutch trouble rather than just old-school calibration.

Est. Repair Cost: £400–£1,500
Warning Signs:

Harsh shifts, Long pause between gears, Gearbox warning, Struggles selecting reverse

What to Inspect:
  • Drive it in traffic and on hills
  • Test reverse repeatedly
  • Look for clutch or actuator invoices

Front suspension top-mount and drop-link wear

ModerateSuspension & Chassis

The C4 rides comfortably, but front top mounts, links and bushes still wear often enough to create the familiar PSA front-end knock.

Est. Repair Cost: £120–£350
Warning Signs:

Knock over potholes, Creaking on lock, Uneven front tyre wear

What to Inspect:
  • Drive over rough roads
  • Inspect front tyres and ride height
  • Review MOT history for repeat suspension advisories
