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 BMW 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.

How to check it: Check with the VIN at a BMW workshop whether the campaign is open and, if not, ask them to look at the index of the vent lines.

On the test drive: what to look and listen for

Taken from each sheet's symptoms and checks. You can tick off what you have already looked at: it is saved only in this browser.

0 of 5 checked

Automatic gearbox

  • Look out for: Harsh shifts (especially engaging D and 1st to 2nd), slipping or jerking; oil leaks from the pan, the mechatronic connector sleeve or the seals.

    Ask them to check: Check the oil level with the official procedure (correct temperature and engine running), look for leaks at the pan, connector sleeve and seals, inspect the pan for impact damage and review adaptation values with ISTA.

Steering

  • Look out for: A creaking noise when turning the steering wheel from one lock to the other.

    Ask them to check: Tell the garage it creaks when turning lock to lock and ask them to apply bulletin SIB 32 05 26 (steering rack bolts) before replacing the rack.

Lighting

  • Look out for: Moisture, condensation or fogging is visible inside one or both upper daytime running lights of the headlights.

    Ask them to check: Ask the workshop to check whether the headlight leaks: if it does, it is replaced; if it is natural condensation, a drying box is fitted where applicable.

Powertrain and engine management

  • Look out for: With Start/Stop off and the car stationary, after about 30–50 seconds at idle there is a slight jolt or change in engine speed that feels like a misfire; no warning light and no fault codes.

    Ask them to check: If there are no codes or warning lights, tell the garage BMW considers it normal operation (SIB 12 11 26) to avoid replacing coils, spark plugs or injectors.

Electrical and electronic systems

  • Look out for: The brake warning lights and a screen message come on; the pedal needs more force; ABS and stability control stop working.

    Ask them to check: Check campaign 0034670200 by VIN at a BMW or MINI dealer; if the brake warning appears, go to the garage straight away.
