Common Problems
BMW M4 Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The S55-powered F82/F83 M4 (2014-2020) and S58-powered G82/G83 M4 (2021-present) are among the most capable straight-six turbo engines ever built, but they are not immune to failure. Crank hub issues on the S55 and oil pump concerns on the S58 dominate UK replacement enquiries. Every rebuilt engine supplied through EngineMarket includes upgraded internal...
S55 Crank Hub Failure - The Most Searched M4 Engine Problem
S55 Crank Hub Failure
Most affected vehicles
BMW M4 Coupe (F82)Convertible (F83)
BMW M4 Coupe (F82), Convertible (F83), Competition (2014-2020, S55B30 all variants including manual and DCT)
Failure mileage range
30,000 - 70,000 miles (often triggered by sudden load changes or aggressive downshifts)
Typical failure window
Root cause
The crank hub is secured by a friction disc rather than a conventional keyway. Under high torque spikes or sudden drivetrain shock, the hub can spin relative to the crankshaft, throwing off cam timing and often causing piston-to-valve contact.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Full Replacement - Crank Hub Upgrade - Prevention before failure | £5,500 - £8,000 | £3,500 - £5,500 | Fit aftermarket pinned or keyed crank hub conversion | Permanent fix if caught early; no further crank hub risk |
| Full Replacement - Rebuilt / Reconditioned Engine - Catastrophic failure | £17,000 - £22,000 | £9,500 - £14,000 | Supply & fit rebuilt S55 with upgraded crank hub, rod bearings, timing chain assembly | 12-month warranty; upgraded components address original failure points |
Our recommendation
If your M4 is still running but you have noticed drivetrain malfunctions or timing faults, a preventative crank hub upgrade is the most cost-effective route at £3,500-£5,500 from a specialist. If the hub has already spun and caused valve or piston damage, replacement is almost always cheaper than attempting a cylinder head rebuild. On an M4 worth £18,000-£35,000, a quality rebuilt engine with an upgraded hub restores reliability and resale value.
