Official recalls: ask before you pay

A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.

  1. Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
  2. Ask an official MINI dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
  3. Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

0 of 2 checked

Known weak points

  • Look out for: Midland manual gearbox with stiff shifts, wearing clutch and gearbox failures (grinding noise); cracked exhaust manifold and failing chain tensioner on the 1.6 Tritec; an ECU causing rough idle or stalling (up to 2003); water pump and supercharger on the Cooper S; engine mounts lasting 2–3 years; power-steering pump; thermostat housing and expansion tank leaking coolant; rust on the tailgate, window regulators and water inside.

    Ask them to check: On the test drive, engage every gear and listen to the gearbox; check the coolant level and the cabin floor; check campaigns by VIN.

Electrical / air conditioning

  • Look out for: Brake lights remain on.

    Ask them to check: Check drains, harness routing and connector corrosion.
