Research for this car

• Generation guide BMW 3 Series F30 (2012-2019): known problems and buying guide

  A practical used car. Prefer a 2016 or later B48 petrol or a B47 diesel, and check the N20 timing chain first.

• Engine guide BMW N47 2.0 diesel (116d to 520d, Mini Cooper D): problems, costs and what to check

  A workable diesel with a costly timing chain weak spot, so buy only with chain proof and check the EGR recall.

Known issues for this car

Before you buy this car

From the generation guide

1. 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.
2. Check the iDrive screen, Bluetooth and navigation for ten minutes. Bad result: freezes, dropouts, dead pixels or an old software version.
3. 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.
4. On a pre-facelift rear-wheel-drive car, ask for proof that the steering gear bolts were replaced with steel. Bad result: no record.

From the engine guide

1. Cold-start rattle (test drive, no scanner). Start the cold engine and listen for a metal rattle at the back of the engine. A rattle that lasts a few seconds is an early warning. Bad: a rattle that stays when warm or under throttle.
2. Chain job invoice (paperwork). Ask for an invoice for a chain job that includes the tensioners and guide rails. Bad: no invoice on a 2007 to 2011 car. Without one, budget 1,500-2,500 EUR (Germany, year not stated), with the gearbox or engine out.
3. Timing fault codes (scanner needed). Read the fault memory. Camshaft timing codes, such as P0016 or P0017, point to a stretched chain. Bad: any camshaft timing code or an engine warning light.
4. EGR recall (check the VIN). Enter the VIN in the KBA or BMW recall check. Recall 14099R covers X3 F25 builds from 2010 to 2014. Bad: an open campaign, or no proof the work was done.
5. Swirl flaps (scanner needed). Read the fault memory for the engine warning light. Bad: the warning light with lost power.
6. Oil history (paperwork). Look for oil changes every 10,000 to 15,000 km with BMW LL-04 oil. Bad: long gaps, or only the 30,000 km Longlife interval.
7. Goodwill (paperwork). Do not count on BMW paying for a chain. Goodwill for chain damage has mostly ended for these builds. Bad: a seller who says BMW will pay.
