Most Common Peugeot RCZ Faults & Repair Costs
1.6 THP Timing Chain Stretch (Prince Engine)
The Prince-engine 1.6 THP is notorious for timing chain stretch and tensioner failure. If the chain jumps, it can cause catastrophic valve-to-piston contact and total engine destruction.
Rattle on cold start, Engine management light, Rough idle, Loss of power
- Start from stone cold and listen for chain rattle
- Check for timing chain invoices
- Verify oil change frequency
Turbo Oil Return Pipe Leaks
The turbo oil return pipe on THP models can develop leaks, causing oil to drip onto the exhaust manifold or subframe. This can produce burning oil smells and, in severe cases, fire risk.
Burning oil smell, Oil drip under the car, Smoke from the engine bay area
- Inspect the turbo area and oil return pipe for wetness
- Look for oil on the exhaust manifold
DMF/Clutch Wear
The dual-mass flywheel and clutch on THP models wear faster than expected, particularly on cars driven hard. Replacement is expensive as the clutch and DMF are usually replaced together.
Judder when pulling away, Rattling at idle with clutch up, Slipping under hard acceleration
- Feel for judder from a standstill
- Listen for DMF rattle with engine running and clutch up
Boot Strut Gas Failure
The gas struts that hold the boot lid open lose pressure over time, making the heavy boot lid drop unexpectedly. This is both annoying and potentially dangerous.
Boot lid will not stay open, Boot drops when opened, Need to hold boot open manually
- Open the boot and see if it stays up on its own
Headlight Condensation and Clouding
The headlight units on the RCZ can suffer from internal condensation and external UV clouding, reducing light output and potentially causing MOT failure.
Water droplets inside headlight lens, Cloudy or hazing lens surface, Reduced night-time visibility
- Inspect both headlights for internal moisture or clouding
