All Known Issues

Crank Hub Slip / Engine Timing Issues

SeriousEngine

The same S55 crank-hub concern that affects F80 M3s also hangs over the F82/F83 M4, especially on tuned cars making repeated hard launches.

Most affected: F82 M4, F83 M4 Convertible, M4 CS, M4 GTS

Estimated cost: £2,000–£8,000Affects: 2014–2020Often appears around: Any mileage on tuned cars

Typical symptoms

  • •Sudden misfire after full boost
  • •Loss of power with timing-related fault codes

What to inspect before you buy

  • ✓Ask about any crank-hub capture or pinned-hub modification
  • ✓Be suspicious of cars with drag-strip style launch abuse

Adaptive Damper / Top Mount Wear

ModerateSuspension & Chassis

Stiff suspension, large wheels, and poor UK roads can leave M4s with worn dampers, noisy top mounts, or poor wheel alignment that chews through tyres.

Most affected: All M4 variants

Estimated cost: £300–£1,800Affects: 2014–2024Often appears around: 20k–60k miles

Typical symptoms

  • •Front-end knock over sharp ridges
  • •Uneven tyre wear or fidgety motorway tracking

What to inspect before you buy

  • ✓Inspect inside shoulders of all four tyres
  • ✓Check that the steering sits straight and the car does not wander

Convertible Roof Water Ingress / Module Risk

ModerateBodywork & Rust

The folding-roof M4 Convertible can suffer from blocked drains, wet boot electronics, or roof-cycle faults if the mechanism has been neglected.

Most affected: F83 M4 Convertible, G83 M4 Convertible

Estimated cost: £150–£2,000Affects: 2014–2024Often appears around: Age-related rather than mileage-related

Typical symptoms

  • •Musty smell in the boot
  • •Roof warning lights or hesitant operation

What to inspect before you buy

  • ✓Lift the boot floor and look for dampness
  • ✓Run the full roof cycle more than once

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.

Most affected: F82/F83 M4, G82/G83 M4

Estimated cost: £120–£900Affects: 2014–2024Often appears around: 20k–60k miles

Typical symptoms

  • •Sweet coolant smell
  • •Low coolant warnings after a hard drive

What to inspect before you buy

  • ✓Inspect the tank cap and seam
  • ✓Look for dried coolant around the nose and undertray

Buying Tips for the 2014 BMW M4

  • ✓Assume any M4 may have been mapped unless you can prove otherwise
  • ✓Inspect carbon-ceramic brakes very carefully because replacement costs are enormous
  • ✓On convertibles, make sure the roof cycle is smooth and the cabin is dry
  • ✓Check rear tyres, alignment, and differential behaviour before you trust the car
