All Known Issues

SMG / DCT / Transmission Heat Stress

SeriousGearbox & Transmission

Fast M5s punish transmissions. E60 SMG hydraulic components, F10 DCT heat stress, and even later automatic driveline components all suffer if the car has been launched repeatedly.

Est. Repair Cost: £500–£5,000
Warning Signs:

Jerky low-speed shifts, Delayed engagement when hot, Drivetrain warning messages

What to Inspect:
  • Drive the car long enough for gearbox temperature to rise
  • Check for transmission fluid service evidence

Coolant / Turbo Cooling Leaks

ModerateCooling System

Turbocharged M5s can develop coolant leaks around expansion tanks, turbo cooling lines, and front heat exchangers. Repeated low-coolant warnings are common on neglected cars.

Est. Repair Cost: £150–£1,200
Warning Signs:

Coolant smell after fast driving, Low coolant alerts without obvious overheating

What to Inspect:
  • Inspect the front coolers and expansion tank seam
  • Look for coolant residue under the belly pan

Buying Tips for 2014 BMW M5

  • ✓On the E60 V10, demand proof of rod bearing and throttle actuator replacement; without this, engine failure is a matter of when, not if.
  • ✓On the F10 V8, check for extreme oil consumption and coolant leaks from the turbo lines located in the hot 'V' of the engine.
  • ✓Inspect the incredibly expensive brake discs on all models; carbon-ceramics (gold calipers) must be weighed to check for wear.
  • ✓Test the M xDrive system on the F90; ensure it switches seamlessly to 2WD mode and there is no binding from the transfer case.
  • ✓Verify the 1,200-mile running-in service was stamped correctly, and check the overall service history for regular diff and gearbox fluid changes.
  • ✓Check the suspension for knocking or leaking adaptive dampers, as the M5 is an exceptionally heavy car that destroys suspension bushes.
