According to the data we have, the engine with the fewest documented faults is the M760Li (6.6 V12) (Petrol).

By fuel, all versions have the same number of documented faults.

We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.

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.
Water in the starter motor: no start or the starter stays engaged (BMW 3, 5 and 7 Series)Electrical and electronic systems

How to check it: Ask a BMW garage to check with the VIN whether either campaign is outstanding; if the starter keeps turning or you smell burning, switch off and do not leave the car next to buildings.

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 4 checked

Cooling / EGR

  • Look out for: Coolant loss with a low-level warning, coolant or oil residue at the rear of the engine; on diesels, internal coolant loss with no visible leak (EGR cooler).

    Ask them to check: Check the coolant level, look for leaks under the water pump and at the oil filter housing, and on diesels confirm by VIN whether the EGR cooler campaign was done.

Cooling / leaks / VANOS

  • Look out for: Temperature warning and limited power with no prior warning (water pump); burning oil smell or smoke from leaks onto the exhaust or belt; rough idle and VANOS codes (2A82, 2A87).

    Ask them to check: Check the water pump and thermostat history, look for leaks at the valve cover and oil filter housing, and read VANOS codes.

High-voltage battery

  • Look out for: Usually none before failure. In rare cases, a battery short-circuit with a fire risk, especially while charging.

    Ask them to check: Confirm by VIN with BMW that the battery recall has been done; if not, do not charge the car until it is 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.

OBD codes worth looking for
