Known faults on the 2015 BMW 5 Series

Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.

  • Timing chain wear

    All engines

    Wear in the timing chain guides and tensioner shows up as a grinding or rattling noise at start-up. Putting it right is a big job with a big bill.

    At the viewing: Start the engine from cold and listen for grinding or rattling in the first few seconds.

  • EGR cooler recall (diesel)

    Diesel

    Over 220,000 BMWs were recalled because the EGR cooler could leak and, in rare cases, cause a fire.

    At the viewing: Ask a BMW dealer to check the VIN for outstanding recalls.

  • Wet passenger footwell

    All engines

    A leak at the heater blower housing can soak the front passenger carpet, often noticed as a musty smell.

    At the viewing: Feel the passenger-side carpet for damp and sniff for mustiness.

  • Cranks but won’t start

    All engines

    A failing fuel pump control unit can stop the engine firing even though it turns over. It has to be replaced.

    At the viewing: Make sure it starts promptly every time you try.

  • Noisy or odd-feeling steering

    All engines

    Air getting into the power steering, usually from a failing pump, makes the steering noisy.

    At the viewing: Turn the wheel lock to lock with the engine running and listen for whining.

    Source: Haynes: BMW 5-Series common problems (2010-2017)

  • Ticking from a front wheel

    All engines

    A brake disc that sits too close to the wheel bearing can tick on every turn. A small spacer fixes it.

    At the viewing: Drive slowly with the window down and listen for ticking.
