Coolant / Charge-Cooling Leaks

ModerateCooling System

Turbocharged M4s can lose coolant from expansion tanks, front coolers, or hoses. It is a common nuisance fault on hard-driven examples and should not be ignored.

Warning Signs:

Sweet coolant smell, Low coolant warnings after a hard drive

What to Inspect:
  • Inspect the tank cap and seam

Buying Tips for 2022 BMW M4

  • ✓Check for signs of aftermarket tuning (bootmod3, piggyback ECUs); tuned cars place immense stress on the infamous S55 crank hub.
  • ✓Inspect the carbon-ceramic brakes (if optioned; indicated by gold calipers) for chipping on the rotor edges; replacement discs cost roughly £4,000 per axle.
  • ✓Verify the front radiators and oil coolers for stone damage; the large grilles leave them exposed to debris on UK motorways.
  • ✓Look closely at the panel gaps and paint finish; M4s are frequently involved in accidents, so check for hidden crash damage.
  • ✓Test the 7-speed DCT gearbox; it should shift with brutal speed in the highest setting, but check for leaks from the transmission pan.
  • ✓Ensure the differential bushes aren't completely worn out, which causes a heavy clunk from the rear end when accelerating hard.
