How much does a BMW M4 F82/F83 engine replacement cost in the UK?

A reconditioned S55 engine typically costs £8,000–£18,000 supply only [BMW-QUOTE], depending on variant -the standard 431 hp engine sits at £8,000–£12,000, while the GTS 493 hp unit can reach £12,000–£18,000. Fitting adds £1,040–£1,430. Use our calculator for a personalised figure.

Which M4 engine is the most reliable?

The S55B30 standard (431 hp) is fundamentally robust -a closed‑deck block with forged internals designed for track use. However, the crank hub is the defining weakness across all S55 variants. The Competition (444 hp) and CS (454 hp) are similar in reliability to the standard car when properly maintained. The GTS (493 hp) with water injection adds complexity and cost.

What are the common problems with the BMW M4 F82/F83?

Crank hub spinning -the S55's single biggest risk -which can cause catastrophic engine failure if not addressed. Rod bearing wear, charge pipe failure (plastic pipes crack under boost), intercooler failure (internal cracks can inject coolant into cylinders), and DCT transmission issues on high‑mileage or tracked cars.

Is the BMW M4 F82/F83 reliable?

The S55 engine is fundamentally robust -it was engineered for track use with a closed‑deck block and forged internals. However, the crank hub is a well‑documented weak point: under aggressive driving, the hub can spin, throwing off engine timing. This is more common on tuned cars and tracked examples. Rod bearing wear and charge pipe failures are also known issues. A well‑maintained M4 with a crank hub capture is a reliable high‑performance machine.

Which M4 engine should I avoid?

No engine outright -but the GTS (493 hp) with water injection adds complexity and parts scarcity. The CS and CSL are higher‑strung variants with similar reliability profiles but higher costs. For most buyers, the standard or Competition cars represent the best balance of performance and reliability.

How do I know if my M4 engine needs replacing?

Key warning signs: crank hub spin -sudden loss of power, engine warning light, metallic noise; rod bearing failure -knocking noise, oil pressure warning; charge pipe failure -boost leak, reduced power; intercooler failure -unexplained coolant loss, misfires. Use our diagnostic calculator for a personalised assessment.

Is it worth replacing an M4 engine, or should I scrap the car?

Depends on the car's value. Against a well‑kept £40,000 M4, a £8,000–£12,000 S55 recon is 20–30% of the car's value -safe. Against a tired £20,000 example, the same recon is 40–60% -borderline. Our 70% BMW threshold is the line: if the lowest viable replacement cost exceeds 70% of the vehicle's current market value, evaluate scrap value first.

How long do M4 engines last?

The S55 can exceed 100,000–150,000 miles with proper servicing. The crank hub is the limiting factor -addressed proactively with a crank hub capture, the engine is robust. Regular oil changes, cooling system maintenance, and charge pipe upgrades are essential. Many track‑oriented owners replace rod bearings at 60k miles as preventative maintenance.

What is the difference between the F82 and F83?

The F82 (2014–2020, this page) is the coupé -the fixed‑roof version with a carbon fibre roof. The F83 (2014–2020) is the convertible -with a folding metal roof, adding 200 kg and slightly different weight distribution. Both share the same S55 engine line‑up and M‑DCT or manual gearbox options. Costs and driving dynamics differ -see the F83 generation page for specifics.

How do I find my BMW M4 engine code?

Listed on the VIN plate and vehicle documentation; the engine number is stamped on the block on the front of the engine near the timing cover. The S55B30 shares the same engine code across all variants -output differences are software‑related.

Overview

BMW M4 F82/F83 -Overview

The F82/F83 is the first‑generation BMW M4, produced from 2014 to June 2020.

It replaced the E92/E93 M3 coupé and convertible, marking BMW's return to the turbocharged straight‑six engine in the M3/M4 lineage. Designed by Florian Nissl, the M4 was built on the F32 4 Series platform with extensive M‑division upgrades: a carbon fibre roof (coupé only), upgraded suspension, brakes, and weight reduction measures. Under the bonnet, the M4 uses the S55B30 twin‑turbo straight‑six -a heavily reengineered version of the N55 with a closed‑deck block, forged internals, and twin mono‑scroll turbos. Power outputs range from 431 hp in the standard car to 493 hp in the GTS with water injection. Transmission choices include a 6‑speed manual or 7‑speed M‑DCT dual‑clutch.

The F82/F83 rule

A £8,000–£15,000 S55 recon against a £20,000–£80,000 M4 sits at 10–75% of the car's value. On a sub‑£25,000 M4, that approaches our 70% BMW threshold -we'll honestly tell you to walk away. Against a well‑kept £40,000+ example, the same recon drops to a routine 20–40% -a repair decision, not a financial one. Value the car first. The crank hub is the single biggest risk -budget for preventative work (£1,200–£2,500) on any tracked or tuned car.

Common Problems

01

S55

Crank Hub Spinning

Affected models:

F82/F83 M4 all variants (2014–2020) with S55 engine.

Typical failure mileage:

30,000–80,000 miles (more common on tuned cars).

Root cause:

The S55's crank hub can spin on the crankshaft under high stress -a well‑documented issue on S55 engines. This causes timing to slip, leading to catastrophic engine damage if not addressed. The issue is more common on tuned cars and those tracked regularly.

Tiered Cost Table

Our Recommendation

If you're buying a tuned M4 or planning to track one, budget for a crank hub capture or pinned crank hub as preventative maintenance -£1,200–£2,500 now is far cheaper than the £8,000–£12,000 replacement that follows a spun hub.

Compare S55 engine prices for your M4

02

S55

Rod Bearing Wear

Affected models:

F82/F83 M4 all variants (2014–2020) with S55 engine.

Typical failure mileage:

50,000–100,000 miles (more common on tracked cars).

Root cause:

While the S55 bottom end is generally reliable, rod bearing wear can still be an issue -particularly with extended high‑rpm use or poor maintenance intervals. Excessive wear can eventually lead to engine failure.

Tiered Cost Table

Our Recommendation

On any high‑mileage or tracked M4, consider rod bearing replacement as preventative maintenance -£800–£1,800 now is cheaper than the £8,000–£12,000 replacement that follows a catastrophic failure. Regular oil analysis can help detect wear early.

Compare S55 engine prices for your M4

03

S55

Charge Pipe Failure

Affected models:

F82/F83 M4 all variants (2014–2020) with S55 engine.

Typical failure mileage:

30,000–80,000 miles.

Root cause:

The S55's factory plastic charge pipes can crack under high boost pressures or in extreme temperatures -leading to boost leaks, reduced power, and engine warning lights.

Tiered Cost Table

Our Recommendation

On any tuned M4, replace the factory plastic charge pipes with aluminium aftermarket versions -£250–£600 now is cheaper than the £800–£1,500 repair that follows a cracked pipe.

Compare S55 charge pipe upgrades for your M4

04

S55

Intercooler Failure

Affected models:

F82/F83 M4 all variants (2014–2020) with S55 engine.

Typical failure mileage:

40,000–80,000 miles.

Root cause:

The S55's factory intercooler can develop internal cracks, injecting coolant into the intake and cylinders -causing misfires, coolant loss, and potential engine damage.

Tiered Cost Table

Our Recommendation

If your M4 shows unexplained coolant loss or misfires, have the intercooler inspected -£300–£700 now is cheaper than the £800–£1,500 repair that follows if ignored.

Compare S55 intercooler repairs for your M4

05

F82/F83

DCT Transmission Issues

Affected models:

F82/F83 M4 with 7‑speed M‑DCT (2014–2020).

Typical failure mileage:

40,000–80,000 miles.

Root cause:

The 7‑speed dual‑clutch transmission is generally strong, but aggressive shifting and track use can lead to accelerated wear, overheated fluid, and poor shifts.

Tiered Cost Table

Our Recommendation

On any M4 with DCT, service the transmission every 30k–40k miles -a £200–£500 service is cheap insurance against the £2,500–£4,500 replacement that follows a failure.
