How much does a BMW M6 F06/F12/F13 engine replacement cost in the UK?

A reconditioned S63 engine for an M6 typically costs £6,000–£11,000 supply only, depending on variant -base and LCI units sit at £6,000–£10,500, while the Competition runs £6,500–£11,000. Fitting adds £650–£1,500. Use our calculator for a personalised figure.

Which BMW M6 F06/F12/F13 engine is the most reliable?

The S63B44T1 (LCI, 575 PS, 2015–2018) -later cars have improved connecting rods and lubrication channels, partially addressing the rod-bearing issues that affect earlier cars. No S63 is immune to the hot-vee design's challenges, but LCI cars are the safest bet. The Competition Package (600 PS) is a close second.

What are the common problems with the BMW M6 F06/F12/F13?

S63 rod bearing wear (particularly on pre-2015 cars), valve stem seal failure (blue smoke on startup), cooling system failures, turbocharger and charge pipe issues, and -unrelated to the engine -the 2016 driveshaft recall affecting F06/F12/F13 models.

Is the BMW M6 F06/F12/F13 reliable?

It depends. The S63 is a high-performance V8 with a 'hot-vee' design that creates extreme under-bonnet temperatures. Early cars (2012–2014) have higher rates of rod-bearing wear -budget for preventative replacement at 50,000 miles. LCI cars (2015–2018) are improved but not immune. The S63 is more reliable than the S85 V10 it replaced, but it still demands a significant maintenance budget.

How do I know if my M6 F06/F12/F13 engine needs replacing?

Metallic knocking from the bottom end (rod bearings), blue smoke on startup (valve stem seals), coolant loss or overheating (cooling system), or loss of power (turbo/charge pipe issues) are the key warning signs. Listen for any unusual noises and check for oil consumption. Use our diagnostic calculator for a personalised assessment.

Is it worth replacing a BMW M6 F06/F12/F13 engine, or should I scrap the car?

Depends on the car's value. Against a well‑kept £35,000 M6, a £7,000 S63 recon is 20% of the car's value -a repair decision, not a financial one. On a sub-£20,000 high-mileage example, the same recon brushes our 70% BMW threshold -walk away. Always check the whole car's condition before committing to a rebuild.

How long do BMW M6 F06/F12/F13 engines last?

The S63 can exceed 100,000 miles with proper servicing, but rod bearings are the limiting factor -preventative replacement at 50,000 miles is recommended. Regular oil changes (5,000-mile intervals) with high-quality oil are essential. The Competition Package's higher output may reduce longevity, but data is limited.

What is the difference between the F06, F12 and F13 M6?

The F13 is the M6 Coupé (2-door), the F12 is the M6 Convertible (2-door), and the F06 is the M6 Gran Coupé (4-door). All three share the same S63 engine and platform, but the F12 Convertible is heavier and has additional structural reinforcement. The F06 Gran Coupé offers the most practicality with the same performance.

How do I find my BMW M6 F06/F12/F13 engine code?

Listed on the VIN plate and vehicle documentation; block stamping is visible from below on the S63 unit. Tell us your variant (M6, M6 Competition, M6 Competition Package) and body style (F06, F12, F13) and year and we'll identify it -20+ vetted BMW M specialists will confirm it for free.

Overview

BMW M6 F06/F12/F13 — Overview

The F06/F12/F13 is the third generation of the BMW M6, produced from 2012 to 2018. It succeeded the E63/E64 M6 (2005–2010) with a switch from the naturally aspirated S85 V10 to a twin-turbocharged S63 V8, delivering 560 PS and 680 Nm of torque. The M6 was offered in three body styles: the F13 Coupé, the F12 Convertible, and the F06 Gran Coupé — a four-door version introduced in 2013.

A 2015 Life Cycle Impulse (LCI) brought a power increase to 575 PS, while the Competition Package offered 600 PS. The M6 was discontinued in 2018, with the M8 taking its place.

04Best & Worst Engines

Best & Worst Engines

Best Petrol Overall

S63B44T1 (3rd-generation, 560–600 PS)

“The S63 is BMW's high-performance V8 — a 4.4-litre twin-turbo unit with a 'hot-vee' design that positions the turbos inside the V of the engine for reduced lag and sharper response. It delivers brutal power — 560 PS in standard form, 600 PS with the Competition Package — and a soundtrack that's pure M. It's more reliable than the S85 V10 it replaced, but still requires diligent maintenance.”

Who it's for: buyers who want the definitive modern M6 experience with the best balance of performance and daily usability.

Best Value

M6 Competition Package (S63B44T1, 600 PS)

“The Competition Package is the M6 most buyers should choose — 600 PS, 750 Nm of torque, and a recalibrated chassis that transforms the car's handling. It's available across all three body styles and offers genuine supercar performance with M6 refinement. The extra 40 PS over the base car is noticeable, and the package holds its value better.”

Who it's for: buyers who want the best all-round M6 without the CSL's track-focused compromises.

Most Expensive Failure

S63B44T1 Full Engine Replacement

“The S63's hot-vee design creates extreme under-bonnet temperatures that accelerate wear on valve stem seals, cooling system components, and turbochargers. Rod-bearing wear is a known issue, particularly in early cars. A full engine replacement can exceed £11,000 — the most expensive M6 engine to repair.”

Who it's for: buyers who understand that maintaining an M6 is a serious financial commitment.

Highest Risk

S63B44T1 (early production, 2012–2014)

“Early S63 engines (2012–2014) have higher rates of rod-bearing wear than later cars. The issue was partially addressed in the 2015 LCI and later TU (Technical Update) versions with revised connecting rods and improved lubrication channels. If buying a pre-2015 M6, check for rod-bearing replacement history. This is the defining risk of the F06/F12/F13 generation.”

Who it's for: buyers who understand that early cars require closer monitoring and a maintenance budget.

Most Overlooked

F06 Gran Coupé (4-door, 2013–2018)

“The F06 Gran Coupé is often overlooked in favour of the F13 Coupé, but it offers a unique proposition — four-door practicality with the same S63 V8 and M6 handling. It's the M6 for buyers who need rear seats but don't want to compromise on performance. The Gran Coupé is also the most visually striking of the three body styles, with a lower, sleeker roofline.”

Who it's for: buyers who want M6 performance with four-door practicality.

The F06/F12/F13 rule

A £6,000–£11,000 S63 recon against a £20,000–£40,000 M6 sits at 15–55% of the car's value -a significant decision. On a sub-£20,000 high-mileage example, that brushes our 70% BMW threshold -we'll honestly tell you to walk away. Against a well-kept £35,000+ example, the same recon drops to a routine 17–31% -a repair decision, not a financial one. Value the car first, and always check for rod-bearing history on pre-2015 cars. Brakes and running costs are also significant -budget accordingly.

Common Problems

S63

Rod Bearing Wear

Affected models:

All F06/F12/F13 M6 variants (S63B44T1, 2012–2018), particularly pre-2015 cars.

Typical failure mileage:

30,000–60,000 miles.

Root cause:

The S63 engine is known for rod-bearing wear, particularly in early production cars (2012–2014). The issue was partially addressed in the 2015 LCI and later TU (Technical Update) versions with revised connecting rods and improved lubrication channels. However, even later cars are not immune. The classic symptom is a metallic knocking sound from the bottom end, particularly when cold. This is the single most expensive failure on the F06/F12/F13 M6.

Tiered Cost Table

Dealer

Specialist

Dealer

Specialist

Our Recommendation

If you own an F06/F12/F13 M6, budget for rod bearing replacement as preventative maintenance at 50,000 miles -£2,000–£4,000 is dramatically cheaper than the £6,000+ replacement that follows if the bearings fail. Listen for any metallic knocking and use the correct 10W-60 oil. This applies to all S63-engined cars, but early pre-2015 cars are the highest risk.

S63

Valve Stem Seal & Cooling System Failure

Affected models:

All F06/F12/F13 M6 variants (S63B44T1, 2012–2018).

Typical failure mileage:

40,000–80,000 miles.

Root cause:

The S63's 'hot-vee' design -turbos positioned inside the V of the engine -generates significant heat that accelerates wear on valve stem seals. The seals harden and lose their sealing ability, allowing oil to seep past and into the combustion chamber. The classic symptom is a puff of blue smoke on cold startup. The cooling system (water pump, thermostat, expansion tank) also fails prematurely due to the extreme under-bonnet temperatures.

Tiered Cost Table

Dealer

Specialist

Dealer

Specialist

Our Recommendation

If your S63 V8 smokes on startup, budget for valve-stem-seal replacement immediately -a £1,500–£3,000 repair is dramatically cheaper than the £6,000+ replacement that follows if the catalytic converters are destroyed or the engine overheats. Regular oil changes (5,000-mile intervals) with high-quality oil are essential.

S63

Turbocharger & Charge Pipe Failure

Affected models:

All F06/F12/F13 M6 variants (S63B44T1, 2012–2018).

Typical failure mileage:

40,000–80,000 miles.

Root cause:

The S63's twin-turbo setup can suffer from turbocharger failures, particularly in tuned or track-used cars. The plastic charge pipes can also crack under boost pressure, causing loss of power and engine warning lights. Upgraded aluminium charge pipes are a popular preventative modification.

Tiered Cost Table

Dealer

Specialist

Dealer

Specialist

Our Recommendation

Consider upgrading the plastic charge pipes to aluminium units if you track your car or plan to tune it. A £500–£1,000 preventative upgrade is dramatically cheaper than the £6,000+ replacement that follows if the turbo fails and causes engine damage.

F06/F12/F13

Driveshaft Recall & Differential Noise

Affected models:

All F06/F12/F13 M6 variants (2012–2018).

Typical failure mileage:

Not mileage-dependent -recall item.

Root cause:

BMW issued a voluntary safety recall (effective July 2016) involving the driveshaft in certain F06 (M6 Gran Coupé), F10 (M5), F12 (M6 Convertible) and F13 (M6 Coupé). The rear differential can also emit a loud noise due to a manufacturing defect in the limited-slip clutch pack.

Our Recommendation

Check if your M6 has had the driveshaft recall performed -this is a free repair from BMW. If you hear loud noises from the rear differential, have it inspected immediately.
