2High Likelihood

Exhaust camshaft wear leading to valve, vacuum pump and head-gasket damage

Hard starting, rough running, poor pull, repeated engine faults, odd airflow codes, brake-assist warnings in some cases, or overheating/pressurising if it has progressed to head-gasket failure.

How to check

Drive it from cold through gentle and moderate acceleration, then let it idle and restart it once warm.

3High Likelihood

Heavy intake and EGR carbon build-up

Sluggish acceleration, hesitation, smoke, rougher running and repeated engine-management faults, often with more frequent regeneration behaviour.
