How to check

Warm the car fully, park it, switch off, then stand by the bonnet area for a minute.

Estimated Repair Cost

£600

2Moderate Likelihood

Automatic gearbox hesitation and mechatronic faults

Jerky pull-away, shunting in traffic, delayed response when pressing the throttle, or occasional gearbox warning messages.

How to check

Creep in slow traffic, then pull away gently several times from a stop.

Estimated Repair Cost

£1,800

3High Likelihood

Higher-than-expected oil consumption

Frequent top-ups between services, low oil warnings, or a seller who keeps spare oil in the boot.

How to check

Measure actual consumption over mileage, rule out leaks and breather faults, then escalate to compression/leak-down and turbo checks if usage is heavy.
