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 components designed to address the original failure point - plus a minimum 12-month unlimited mileage warranty. Below, we break down the most common failure modes, what they cost to fix at a dealer versus a specialist, and when replacement makes more sense than repair.

The Most Searched M4 Engine Problem
BMW M4 Coupe (F82), Convertible (F83), Competition (2014-2020, S55B30 all variants including manual and DCT)
30,000 - 70,000 miles (often triggered by sudden load changes or aggressive downshifts)
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 Tier | Dealer Price | Specialist Price | What It Involves | Longevity / Suitability |
|---|---|---|---|---|
Full Replacement - Crank Hub Upgrade - Prevention before failure Best Value | £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 Best Value | £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 |
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.
Engine failure on an M4 can feel like the end of the road, but specialist rebuilt engines offer a cost-effective alternative to main dealer prices or scrapping the car. Whether you are dealing with S55 crank hub failure, rod bearing wear, or S58 oil pump issues, EngineMarket makes it simple to compare prices from trusted UK BMW M4 specialists. Every rebuilt unit includes upgraded components designed to address the original weak point, a minimum 12-month unlimited mileage warranty, and nationwide delivery with supply & fit options available.

FAQ
Question 1
£9,500-£16,500 for a rebuilt S55 (F82/F83) and £14,500-£24,000 for a rebuilt S58 (G82/G83) supply-only. Specialist prices are typically 30-40% below main dealer quotes for the same work.
Key points
Question 2
Yes - it's the Achilles' heel of the S55. When the crank hub spins, it throws engine timing off, often causing pistons to hit valves. Prevention costs £2,000-£3,500; full engine replacement costs £9,500+.
Key points
Question 3
Yes - the S58 uses a closed-deck block and forged internals that handle far more abuse. BMW drift cars run 1,000hp through stock S58 crankshafts with minimal wear after years of racing .
Key points
Question 4
Crank hub failure dominates replacement enquiries, followed by rod bearing wear (50k-90k miles) and turbocharger oil seal failure around 54k-70k miles. Each can destroy the engine if ignored.
Key points
Question 5
Replace it. An M4 with a fresh rebuilt engine is worth £18,000-£35,000 depending on year and variant. A quality rebuilt S55 costs £9,500-£14,000 - far less than the £20,000+ depreciation on a replacement car.
Key points
Question 6
Well-maintained S55 engines typically reach 100k-150k miles. S58 engines are newer but expected to exceed this. Crank hub failure can strike at any mileage - it's mileage-independent and driven by driving style.
Key points
Question 7
Yes - many specialists offer upgraded internals during replacement. Stage 1 builds with forged rods and upgraded turbos are common. Stock S58 internals handle 1,000hp without modification .
Key points
Question 8
Rebuilt engines are stripped and reassembled with new wear parts (typically £9,500-£14,000). Reconditioned means cleaned and tested with selective part replacement. Used engines are as-removed from donor cars (£4,500-£8,000).
Key points
Question 9
Yes - most specialist suppliers offer fitting through their garage networks. Budget £850-£1,500 for professional installation including ISN coding, immobiliser synchronisation and full system testing.
Key points
Question 10
Check the engine block stamp (S55B30 for F82/F83, S58B30 for G82/G83), look at your V5C logbook, or enter your registration above for instant identification. Competition models use the same base codes but different ECU mapping.
