What to look out for

The checks worth doing on a BMW M4 before you hand over any money. Every documented fault is listed below, each with its own page.

  • Costly issue

    Any detectable play indicates replacement is needed.

    See why

    Front lower control arm ball joint premature wear

    The F82 and G82 M4 share the M-specific front suspension geometry with the M3, and the front lower control arm ball joints are documented to wear prematurely compared to non-M 4 Series models. Higher lateral loads from aggressive driving, wider track and stiffer suspension accelerate ball joint wear. This pattern persists into the G82 generation. Failed ball joints cause vague steering and risk of directional loss in extreme cases.

    What you would notice

    • Clunking noise from front suspension over bumps or during steering inputs
    • Vague or imprecise steering feel
    • Excessive tyre wear on inner or outer edges
    • Wandering or instability at motorway speeds

    Typically $900–$2,200 to put right.

  • Costly issue

    Inspect the coolant expansion tank closely for hairline cracks, particularly at the seam and around the pressure cap neck.

    See why

    S55 coolant expansion tank and oil cooler housing crack

    The F82 M4 with the S55 engine uses a plastic coolant expansion tank and a thermoplastic oil cooler housing that are known to crack under thermal cycling, causing coolant loss and potential overheating. The expansion tank plastic becomes brittle with age and heat exposure, developing hairline cracks at the seam and around the cap neck. Separately, the oil cooler thermostatic housing can also crack or develop sealing failures. Both are common on cars over five years old or 80,000 km.

    What you would notice

    • Coolant warning light or low coolant level with no visible puddle undercar
    • Coolant smell from engine bay after a run
    • Visible crack or weeping at coolant expansion tank seam or cap area
    • Overheating if crack advances and coolant loss is significant

    Typically $400–$1,200 to put right.

A 2014 BMW M4: what is due, and when

Servicing

Nothing left on the schedule

Every milestone is behind this car. The ones below are the receipts worth asking for.

Placed by the car’s age, not read from the dash — 82,800–193,200 km after 12 years.

Timing

Our research does not record which this engine uses, and it depends on the engine rather than the model. Check the owner’s manual rather than assume: on a belt-driven engine, an overdue belt is the failure that takes the engine with it.

Behind it

  • 60,000 kmMarks the point where spark plugs and ignition coils are due for a refresh to maintain optimal combustion.
  • 80,000 kmInspect the cooling system hoses and expansion tank for fatigue from heat cycling.
  • 100,000 kmPreventative review of the suspension dampers and water pump condition recommended - frequent maintenance items around this stage.

“Behind it” means the car has driven past that distance, not that the work was done — ask to see the receipts. These are the intervals for the F82 M4 Coupe · 3.0L S55 Twin-Turbo - Base model · Petrol; only the car’s own service book says what has actually been done to it.

02Takata driver airbag inflator recall PRA 2018/17191 (F82/F83 M4, 2014-2017)

Some 2014 to 2017 F82/F83 M4 cars (all engines) were built with a Takata driver's airbag whose propellant can absorb moisture over time.2014–2017Interior
OccasionalInterior $0–$1,500 to fix

Some 2014 to 2017 F82/F83 M4 cars (all engines) were built with a Takata driver's airbag whose propellant can absorb moisture over time. In a crash the inflator can over-pressurise and rupture, throwing metal fragments at the driver, which can cause serious injury or death. BMW Australia recalled F Series cars in a staged campaign from December 2018 (PRA 2018/17191) to replace the airbag free of charge, and a separate 2024 recall (REC-006035) covers cars later fitted with a steering wheel that has a Takata inflator. Have the VIN checked to confirm the recall work is done. Not every car is in the recall; a dealer check of the VIN is the only way to know.

Symptoms to notice

  • No visible symptom: the defect only shows when the airbag deploys
  • Airbag warning light on the dash may indicate an airbag module has been disturbed or replaced with a non-genuine part

What to check

  1. Ask the seller for the BMW dealer invoice showing the Takata driver airbag recall (PRA 2018/17191) was done, and ring a BMW dealer with the VIN to confirm there are no open airbag recalls.
  2. Check the airbag warning light comes on at start-up and goes out after a few seconds.
  3. Look at the steering wheel: if it has been swapped for a different style, ask where it came from, because swapped wheels are covered by a separate Takata recall (REC-006035).
  4. If a workshop inspection is possible: have a BMW dealer read the vehicle recall history by VIN and check the airbag module part label against the recall list.

Where to look: Driver airbag in the centre of the steering wheel

Ask the seller

  • “Has the Takata driver airbag recall been done, and do you have the dealer invoice?”
  • “Has the steering wheel ever been replaced or swapped for a different style?”
  • “Has the airbag warning light ever come on?”

CommonSuspension $900–$2,200 to fix

The F82 and G82 M4 share the M-specific front suspension geometry with the M3, and the front lower control arm ball joints are documented to wear prematurely compared to non-M 4 Series models. Higher lateral loads from aggressive driving, wider track and stiffer suspension accelerate ball joint wear. This pattern persists into the G82 generation. Failed ball joints cause vague steering and risk of directional loss in extreme cases.

Symptoms to notice

  • Clunking noise from front suspension over bumps or during steering inputs
  • Vague or imprecise steering feel
  • Excessive tyre wear on inner or outer edges
  • Wandering or instability at motorway speeds

What to check

Any detectable play indicates replacement is needed. Inspect the rubber boot for cracking or grease loss. Check both sides simultaneously. If a workshop inspection is possible: Lift the vehicle and check front lower ball joints for play by gripping the tyre at 6 and 12 o'clock positions and rocking firmly.

Where to look: Front lower control arm, ball joint at wheel carrier attachment point

Parts involved: Ball joint.

Ask the seller

  • “Have the front control arm ball joints been replaced?”
  • “When were the front suspension components last inspected?”
  • “Has the car experienced any hard kerb strikes or suspension impacts?”

01S55 crank hub slip and jumped valve timing (M4 3.0)

The S55 3.0 twin-turbo six in the F82 and F83 M4 holds its timing chain sprocket to the crankshaft hub by friction rather than a key.petrol2014–2020Engine
OccasionalEngine $3,000–$30,000 to fix

Can't confirm for this car

The S55 3.0 twin-turbo six in the F82 and F83 M4 holds its timing chain sprocket to the crankshaft hub by friction rather than a key. Under heavy load or a hard downshift the hub can rotate, knocking the valve timing out. Mild cases bring a Drivetrain Malfunction warning; bad cases bend valves and need an engine rebuild. Tuned cars are most at risk, but stock cars have failed too. There is no recall; the fix is an aftermarket pinned or keyed crank hub.

Symptoms to notice

  • Drivetrain Malfunction or engine warning light after hard driving
  • Rough running or misfire after a high-rev downshift
  • Loss of power
  • Engine will not start or runs very badly after a failure

What to check

Ask whether the car is tuned (ECU flash, downpipes, bigger turbos) and whether an upgraded pinned or keyed crank hub has been fitted, and ask for the invoice. Look for aftermarket parts under the bonnet and listen for a smooth idle. On the test drive watch for any Drivetrain Malfunction warning. A tuned car with no crank hub upgrade carries more risk and should be priced to suit. If a workshop inspection is possible: have a BMW specialist read the engine fault memory for camshaft or crankshaft correlation faults.

Where to look: Front of the engine, behind the crankshaft pulley, at the bottom of the timing chain

Parts involved: Timing chain, Turbocharger.

Ask the seller

  • “Has the engine ever been tuned or remapped?”
  • “Has an upgraded pinned or keyed crank hub been fitted, and can I see the invoice?”
  • “Has the car ever shown a Drivetrain Malfunction warning?”
  • “Has the car been used on track?”

02S55 rod and main bearing failure

Check full service history for oil change intervals and specification.petrol2014–2020Engine
OccasionalEngine $12,000–$28,000 to fix

Can't confirm for this car

The S55 3.0 twin-turbo straight-six in the F82 M4 has a well-documented rod and main bearing failure pattern at higher mileages and following hard or track use. The bearings run tighter clearances than the standard N55, and degraded oil or extended drain intervals cause accelerated wear. Spun or wiped bearings result in catastrophic engine failure. Hundreds of cases are documented on BMW M specialist forums. ACL and King aftermarket bearings at correct clearance are a widely-used preventive measure, often installed proactively at 50,000 to 80,000 km.

Symptoms to notice

  • Knocking or tapping noise from lower engine under hard acceleration (rod knock)
  • Low oil pressure warning light, particularly under hard cornering or acceleration
  • Sudden loss of power followed by engine seizure in advanced cases
  • Metal particles or shavings visible in oil during a service drain

What to check

  1. Check full service history for oil change intervals and specification.
  2. Intervals beyond 10,000 km or non-LL-01 spec oil significantly increase risk.
  3. Listen for any knocking under hard acceleration.
  4. Ask about track use.
  5. Confirm whether preventive bearing replacement has been performed.
  6. If a workshop inspection is possible: Oil analysis is strongly recommended before purchase.

Where to look: S55 engine lower end, connecting rod and main bearing journals on the crankshaft

Parts involved: Turbocharger.

Ask the seller

  • “What oil change interval and specification has been used throughout ownership?”
  • “Has the car been driven on track or in any performance driving events?”
  • “Have the rod or main bearings been inspected or replaced with aftermarket units?”
  • “Has an oil analysis ever been performed?”

01S58 main bearing failure (early production batch)

Verify the VIN against any BMW service actions or TSBs for S58 bearing specification.petrol2021 onwardEngine
RareEngine $10,000–$25,000 to fix

Does not apply

Early production S58 3.0 twin-turbo engines in the G82 M4 were subject to a BMW TSB addressing main bearing clearance tolerance deviations in engines produced during 2020 to 2022. Affected units can develop premature main bearing wear leading to oil pressure loss and potential engine failure. BMW issued revised bearing specifications and a dealer service action for affected VIN ranges. Verify against BMW dealer records before purchasing any early G82 M4.

Symptoms to notice

  • Low oil pressure warning on cold or hot start
  • Knocking from engine lower end under load or hard acceleration
  • Oil consumption beyond the expected rate
  • Engine failure without audible warning in severe cases

What to check

  1. Verify the VIN against any BMW service actions or TSBs for S58 bearing specification.
  2. Check full service history for oil change intervals and specification used.
  3. Confirm with a BMW dealer whether this specific vehicle falls within the affected production build range and whether the service action has been completed.

Where to look: S58 engine lower end, main bearing journals on the crankshaft

Parts involved: Turbocharger.

Ask the seller

  • “Has the car been checked against BMW TSBs for S58 bearing specification?”
  • “Has any BMW dealer service action been performed on this engine?”
  • “What oil change interval and specification has been followed?”
