At a glance

  • Years: 2012 to 2019. The 2015 facelift added LED headlights and the B48 and B47 engines.
  • Reliability: 3/5. The N20 timing chain and the xDrive driveline pull the score down. B48 and B47 cars do better.
  • DIY: 2/5. The timing chain job and steering fault codes need a workshop and a BMW-capable scanner.
  • Biggest risks: the N20 timing chain, the brake vacuum pump recall on 2012-2013 N20 cars, and worn xDrive parts.
  • Prefer: a 2016 or later B48 petrol, or a B47 diesel with a full service record. Avoid: early N13 and N20 cars with no timing chain work on record.

Engines and gearboxes

  • 1.6 N13 (N13B16A, 316i and 320i to 2015): avoid. Oil use is high, and the timing chain weakens after about 100,000 km.
  • 2.0 N20 (N20B20A, N20B20B, 320i and 328i): the chain, oil pump and VANOS problems are in the table below. Cars built to about 2015 carry the most risk.
  • 1.5 B38 (B38B15A, 318i from 2015): no common fault found in this guide. Ask for the service record.
  • 2.0 B48 (B48B20A, B48B20B, 320i and 330i from 2016): prefer. Valve stem seals harden, and oil use can rise up to about 100,000 km. Check the oil level between services.
  • 3.0 N55 (N55B30A, 335i): no common fault in this guide. Ask whether the engine was tuned.
  • 3.0 N57 (N57D30A, N57D30B, 330d and 335d): no common fault in this guide. Check the service book for regular oil changes.
  • 3.0 B58 (B58B30A, 340i): no fault data in this guide.
  • 2.0 B47 (B47D20A, B47D20B, 318d, 320d and 325d from 2015): the preferred diesel. Its own guide covers the EGR valve and turbo. BMW B47 diesel
  • 2.0 N47 (N47D20C, N47D20D, 316d to 325d, 2012-2015): the timing chain and EGR cooler are in its own guide. BMW N47 diesel
  • M3 (F80, S55B30A): a separate car with its own faults. Not covered here.
  • 6-speed manual: the dual-mass flywheel (a damper between engine and gearbox) lasts about 100,000-150,000 km according to Kolesa, and Auto.ru says it may need replacing at high mileage.
  • ZF 8HP automatic: see its own guide. ZF 8HP automatic

Before you buy

  1. Start the cold engine and listen for a rattle in the first seconds. Read stored codes P0016 and P0017 with a scanner. Bad result: a rattle, those codes, or no proof of timing chain work.
  2. Read the steering warning lamp and stored codes with a scanner. Bad result: a warning lamp, a pull or drift, or no repair record for the sensor or steering software.
  3. Check the iDrive screen, Bluetooth and navigation for ten minutes. Bad result: freezes, dropouts, dead pixels or an old software version.
  4. Drive away gently and listen for knocks or jerks from under the car. Ask for transfer case oil change records every 50,000-60,000 km. Bad result: knocks, jerks or no oil change record.
  5. Check for overheating warnings and ask whether the electric coolant pump was replaced. Bad result: a temperature warning, or no pump replacement on a car over about 100,000 km.
  6. Lift the car and check the front shocks, ball joints and stabiliser links. Bad result: play in the joints, leaking shocks or knocks over bumps.
  7. On a pre-facelift rear-wheel-drive car, ask for proof that the steering gear bolts were replaced with steel. Bad result: no record.
  8. Ask a BMW dealer to check open recalls for the car's VIN. Bad result: an open brake vacuum pump campaign.
