All Known Issues

Rear Differential Noise / Mount Wear

SeriousGearbox & Transmission

A whining rear differential or a heavy clonk when taking up drive is common on cars that have seen repeated launches or track work. Diff oil neglect and worn rear mounts make the problem worse.

Most affected: M2, M2 Competition, M2 CS, G87 M2

Estimated cost: £350–£2,000Affects: 2016–2024Often appears around: 30k–70k miles on hard-used cars

Typical symptoms

  • •Whine that rises with road speed
  • •Thump from the rear when engaging first or reverse

What to inspect before you buy

  • ✓Check for evidence of recent differential oil changes
  • ✓Drive slowly on full lock and listen for chatter or graunching

Front Suspension Arm / Top Mount Wear

ModerateSuspension & Chassis

The short wheelbase and stiff M chassis mean front tension struts, top mounts, and drop links take a beating on UK roads. Cars that have hit kerbs or potholes can feel nervous at motorway speed.

Most affected: All M2 variants

Estimated cost: £250–£900Affects: 2016–2024Often appears around: 20k–60k miles

Typical symptoms

  • •Knock over broken surfaces
  • •Steering that feels darty or tramlines badly

What to inspect before you buy

  • ✓Inspect inside-edge tyre wear
  • ✓Look for uneven front ride height or non-matching alignment settings

Charge Pipe / Boost Leak Issues

ModerateEngine

N55 and S55-powered cars can develop boost leaks from cracked plastic charge pipes or split boost joints, especially on mapped cars. Power drops off sharply when this happens.

Most affected: F87 M2, M2 Competition, M2 CS

Estimated cost: £150–£500Affects: 2016–2021Often appears around: 20k–50k miles

Typical symptoms

  • •Sudden loss of boost
  • •Hissing under hard acceleration
  • •Check-engine light after a full-throttle pull

What to inspect before you buy

  • ✓Ask whether the car has been tuned
  • ✓Inspect boost pipe joints for oily residue

Cooling System Leaks (B58 / S58 Cars)

ModerateCooling System

Later M2 models can suffer from minor coolant loss around the expansion tank, hose joints, or auxiliary cooling hardware. It is rarely catastrophic at first, but it should not be ignored on a high-output turbo engine.

Most affected: M2 Competition, M2 CS, G87 M2

Estimated cost: £120–£700Affects: 2019–2024Often appears around: 15k–50k miles

Typical symptoms

  • •Sweet coolant smell after a spirited drive
  • •Low coolant warnings with no obvious external puddle

What to inspect before you buy

  • ✓Inspect the tank seam and cap area
  • ✓Check for dried coolant traces around front-mounted coolers

Buying Tips for the 2020 BMW M2

  • ✓Check for track use: blued brake discs, repeated tyre brand changes, and heat-marked calipers are big clues
  • ✓Listen for differential whine and feel for driveline clonks when reapplying throttle
  • ✓On manual cars, check clutch bite and look for missed-shift abuse; on DCT cars, ensure shifts stay clean when hot
  • ✓Inspect the front end very carefully for crash damage and poor paintwork repairs
