Known faults on the 2002 MINI hatch

Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.

• Head gasket and liner problems (1.4 diesel)

• Oil leaks and brittle plastics (1.6 petrol)

  1.6 petrol

  The 1.6 petrol can leak oil from the sump and cam cover gaskets. Plastic parts go brittle; if the dipstick handle breaks and falls into the sump it can wreck the engine.

  At the viewing: Look for oil around the engine and underneath, and check the dipstick handle is intact.

• Low oil pressure after servicing

  Petrol

  Low oil pressure can mean the cartridge oil filter was fitted wrongly at the last service.

  At the viewing: Make sure the oil warning light goes out straight after starting, and listen for tapping from the engine.

• Gearbox bearing and differential noise

  Manual gearbox

  Early cars used a Midland gearbox where a rattle or hum can mean a worn bearing, and clicking can mean a failing differential. The later Getrag box (from mid-2004) wears less but shouldn't jump out of gear.

  At the viewing: Listen for rattles at idle and hums on the move, and make sure every gear engages and stays in.

• Misfires and worn engine mounts

  Petrol

  Worn coils or leads, or oil in the spark plug wells, cause misfires. Worn engine mounts cause judder when pulling away.

  At the viewing: Check it idles smoothly and pulls away without judder.

• Water leaks and damp boot

  All engines

  The frameless front windows can seal badly, and the rear lights and tailgate handle trim often let water in.

  At the viewing: Lift the boot floor and check for damp or a musty smell.

  All engines

  Neglected cars can rust at the rear sill edges, around the front bumper and in the arches.

  At the viewing: Look along the sills and wheel arches for bubbling paint.
