Years: 2014 to 2021, facelift from 2017. Timing chains on the early N20 and on the N55 are the main risks.
Reliability: 3/5. Timing chain reports on the N20 and N55 pull the score down. The sources name no fault for the B48, B58 or manual gearbox.
DIY: 2/5. Chain work is engine work. Use a workshop that can read fault codes.
Prefer: a 2016 or later car with full service records. ZR.ru advises the B48 petrol over the N20 from 2016 on.
Avoid: early N20 and N55 cars with no timing chain work on record.

Ask for proof of timing chain work on an N20 car. Start the cold engine and listen for a rattle. A scanner reads the fault codes. Bad result: a cold-start rattle, fault codes, or no record of chain work by 100,000 km.
Ask whether the fuel pump was replaced. A warning lamp for the fuel system or an engine that cuts out while driving are bad signs. A scanner reads the fault codes. Bad result: either sign, or no record of pump work.
On an N55 car, listen to the engine on a cold start and under load. Ask for the oil change records. Bad result: a rattle, a knock, or no oil change record.
Ask a BMW dealer to check the VIN for open EGR cooler campaigns (KBA reference 008124). Bad result: an open campaign, or no proof that the cooler was replaced.
On a 2014 or 2015 car, turn the wheel at low speed. Bad result: heavier steering, a steering warning lamp, or no record of steering work.
