The essentials.

4 documented, sourced faults across its 3 engines.
3 of them depend on the equipment or the production date: ask what this car has.
We have no official recalls on record for this model; ask anyway, with the chassis number (VIN).
According to the data we have, the engine with the fewest documented faults is the M60i (Petrol).

M60i

Petrol

We have no faults specific to this engine, only those common to every version.

Which engine has the fewest documented faults?

Documented faults and recalls by engine for the BMW X7 (G07)
Engine	Documented faults
xDrive40d (B57)Diesel	32 with conditions
xDrive40i (B58)Petrol	43 with conditions
M60iPetrolFewest documented	11 with conditions

According to the data we have, the engine with the fewest documented faults is the M60i (Petrol).

By fuel type, the one with the fewest documented faults is: Diesel.

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

We have no official recalls on record for this model. Our list is not complete: ask anyway, with the chassis number.

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.
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.
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.

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

B-engine coolant leaks and EGR cooler
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.

Automatic gearbox

ZF 8HP oil level, leaks and harsh shifts
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.

Cooling

Coolant leaks in extreme cold from the quick-connector O-rings
Look out for: Only in severe cold (−15 °C or below): a "top up coolant" warning and some fluid under the car. At normal temperatures it does not leak and the engine temperature is fine.
Ask them to check: Note the outside temperature when the warning appears and only check the level with the engine cold. At the garage, have them look for the leak at the coolant pipes' quick connectors, including the low-temperature circuit.

Powertrain and engine management

Slight jolt at idle after 30–50 s stationary with Start/Stop off (B58 mild hybrid): it is normal
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.

OBD codes worth looking for

If they let you read the fault memory with an OBD reader, these are the codes mentioned in this model's sheets:
