All Known Issues

EGR Cooler Leak (Diesel)

SeriousExhaust & Emissions

Leaking coolant in the diesel EGR system can mix with soot and create a fire risk (Recall 18V755). UK recall completion matters more than a seller saying it has been checked.

Most affected: 316d, 318d, 320d, 320ed, 325d, 330d, 335d

Estimated cost: £0 (Recall)Affects: 2012–2019Often appears around: Usually 40,000 miles plus, but recall status is the main issue

Typical symptoms

  • •Coolant loss with no obvious leak
  • •Sweet smell after shutdown
  • •Engine-management light or drivetrain warnings

What to inspect before you buy

  • ✓Verify recall completion (Recall 18V755) against the VIN
  • ✓Inspect around the EGR cooler for staining or white residue
  • ✓Be careful with cars that have had repeated coolant top-ups

Steering Rack Rattle

ModerateSteering

The EPS rack can develop internal play, often cured with the BMW thrust-piece kit but sometimes needing a complete rack.

Most affected: 316d, 318d, 320d, 320i, 328i, 330d, Touring and GT

Estimated cost: £200–£1,200Affects: 2012–2017Often appears around: 40,000-100,000 miles

Typical symptoms

  • •Knock through the steering on broken surfaces
  • •Light vagueness around centre
  • •Noise when gently rocking the wheel at low speed

What to inspect before you buy

  • ✓Drive the car over patchy surfaces and speed humps
  • ✓Ask whether the thrust-piece repair has been performed
  • ✓Inspect front tyres and control arms because they can mask each other's symptoms

Door Mirror Motor Failure

MinorBodywork & Rust

The power-fold mirror motors seize or lose calibration, leaving mirrors stuck open or folded and making the car feel more tired than its mileage suggests.

Most affected: SE, Sport, Luxury, M Sport, Touring

Estimated cost: £150–£300Affects: 2012–2019Often appears around: Age-related, especially 6+ years old

Typical symptoms

  • •One mirror folds slower than the other
  • •Buzzing from the housing
  • •Mirror stops half-way

What to inspect before you buy

  • ✓Cycle both mirrors several times
  • ✓Inspect for cracked housings after car-park knocks
  • ✓Check memory-seat cars still return to the same positions

Buying Tips for the 2016 BMW 3 Series (F30/F31/F34)

  • ✓Pre-2015 320i/328i cars need careful listening for N20 timing-chain whine and proof of guide work
  • ✓Check the steering, front wishbones, and tyres on rough roads - these cars hide wear badly until they are on UK B-roads
  • ✓Insist on completed diesel EGR recall evidence, especially on 318d, 320d, and 330d variants
  • ✓Touring models should have a dry boot and a smooth electric tailgate with no latch hesitation
