How much does a BMW 5 Series F10 engine replacement cost in the UK?

A reconditioned F10 engine typically costs £2,200–£15,000 supply only, depending on engine -the four-cylinder petrol sits at £2,200–£4,000, while the S63 V8 in the M5 can reach £9,000–£15,000. Fitting adds £650–£1,560. Use our calculator for a personalised figure.

What are the common problems with the BMW 5 Series F10?

Timing chain stretch on the N47 diesel, timing chain guide failure on the N20 four-cylinder petrol, valve stem seal and turbo coolant line failures on the N63 V8, crank hub and rod bearing issues on the S63 M5, and -unrelated to the engine -the occasional electrical gremlins and suspension component wear.

Is the BMW 5 Series F10 reliable?

Reliability varies significantly by engine choice. The N57 diesel and N55 petrol are the most dependable, while the N47 and N20 have well-documented timing chain issues. The N63 V8 is the most complex and expensive to maintain, and the S63 in the M5 demands meticulous maintenance. A well-maintained F10 can be a rewarding car; a neglected one will be expensive.

Which BMW 5 Series F10 engine should I avoid?

The N47 diesel (pre-2014 518d/520d/525d) without documented timing chain replacement -failure is catastrophic and expensive. The N20 four-cylinder (pre-2015 520i/528i) without timing chain guide history is also a risky purchase. The N63 V8 (550i) should only be bought with meticulous service history and a healthy repair budget.

How do I know if my F10 engine needs replacing?

Cold-start rattle (N47 timing chain), whining noise from the engine (N20 timing chain), blue smoke on start-up (N63 valve stem seals), overheating with no obvious external leak (cooling system failure), or rough idle and check engine lights are the key warning signs. Use our diagnostic calculator for a personalised assessment.

Is it worth replacing a BMW 5 Series F10 engine, or should I scrap the car?

Depends on the car's value. Against a £7,000 F10, a £4,500 N57 recon is 64% -borderline but within our 70% BMW threshold. Against a well-kept £12,000+ example, the same recon is 33–38% -a repair decision, not a financial one. Against a sub-£5,000 example, a major engine failure is a write-off. On an M5, the calculus is different -the car's value justifies the S63's high replacement cost.

How long do BMW 5 Series F10 engines last?

The N57 diesel six can exceed 200,000–300,000 miles with proper servicing. The N55 petrol six is similarly durable. The N47 and N20's limiting factor is the timing chain -addressed proactively, either can reach high mileage. The N63 V8 can also reach high mileage but requires meticulous cooling system maintenance. The S63 is robust but requires crank hub and rod bearing preventative work.

What is the difference between the F10 and the E60?

The F10 is the sixth-generation 5 Series (2010–2017), built on the L6 platform with a larger footprint, more advanced technology, and a range of turbocharged engines. The E60 is the fifth-generation 5 Series (2003–2010), built on the E60 platform with a wider range of naturally aspirated and turbocharged engines. The F10 is significantly more refined and technologically advanced, with the F10 M5 introducing the S63 V8.

Overview

BMW 5 Series F10 — Overview

The F10 is the sixth generation of the BMW 5 Series, unveiled on 23 November 2009 and produced from January 2010 to 2017. Built on the BMW L6 platform shared with the F01 7 Series and F12 6 Series, the F10 introduced a turbocharged V8 engine, an 8-speed automatic transmission, and a dual-clutch transmission in the M5.

The F10 was also the first 5 Series to offer a hybrid drivetrain (ActiveHybrid 5).

Market Intelligence

As a model that ended production in 2017, the F10 is now a used-market staple — the 520d remains the most common variant, while the 535d and M5 are the most sought-after performance options.

04Best & Worst Engines

Best & Worst Engines

Thin-Data Summary

The F10's engine range spans four distinct eras. The N57 3.0-litre six-cylinder diesel (530d/535d) is the most dependable engine in the range — proven common-rail injection, strong torque delivery, and a reputation for exceeding 200,000 miles with routine servicing. The N55 3.0-litre turbocharged six (535i) is the best petrol option — smooth, responsive, and more reliable than the N63 V8. The N63 4.4-litre twin-turbo V8 (550i) is the most complex — the "hot-vee" design leads to heat-related failures including valve stem seals and turbo coolant lines. The N47 2.0-litre diesel (520d) is the volume choice but carries a well-documented rear-mounted timing chain risk. The S63 in the M5 is a high-performance twin-turbo V8 with 553–575 bhp, but it demands meticulous maintenance and has known crank hub and rod bearing concerns. If you're buying an F10, the N57 diesel is the sensible choice; the N55 is the petrol sweet spot; the N47 requires documented chain history; the N63 demands deep pockets.

The F10 rule

A £4,000–£7,500 N57 recon against a £7,000 F10 sits at 57–107% of the car's value -right at our 70% BMW threshold. Against a well-kept £12,000+ example, the same recon drops to 33–63% -a repair decision, not a financial one. Against a sub-£5,000 F10, a major engine failure is a write-off. Value the car first.

Key Takeaways

Which F10 Costs Least To Own?
N57 530d -proven six-cylinder diesel with strong reliability.

N57 530d -six-cylinder torque without the M5's running costs.

Common Problems

N47

Diesel Timing Chain Stretch

Affected models:

F10 518d, 520d, 525d (2010–2014, N47 engine).

Typical failure mileage:

60,000–120,000 miles.

Root cause:

The N47's timing chain is mounted at the rear of the engine, making it a major labour-intensive job to replace. The chain, guides, and tensioners can wear prematurely, causing chain stretch. If the chain stretches too far, it can "jump" a tooth or snap, causing pistons to strike open valves. Cold-start rattle for 1–2 seconds is the classic early warning.

Our Recommendation

At the first sign of cold-start rattle on an N47 diesel F10, get the timing chain inspected immediately. A £1,000–£1,800 preventative repair is dramatically cheaper than the £2,500–£4,500 replacement that follows if ignored. On an F10 worth under £5,000, this decision alone determines whether the car stays economically viable. Consider the B47-equipped cars (2014–2017) which have an improved chain design.

Compare N47 engine prices for your F10

N20

Timing Chain Guide Failure

Affected models:

F10 520i, 528i (2011–2016, N20 engine).

Typical failure mileage:

40,000–80,000 miles.

Root cause:

The N20's timing chain guides are made of a plastic material that can become brittle and fail over time. When the guides break, the timing chain can slip or snap, causing catastrophic engine damage. A whining noise from the engine, particularly on cold start, is the classic early warning.

Our Recommendation

At the first sign of a whining noise from the engine on an N20-powered F10, get the timing chain inspected immediately. An £800–£1,800 preventative repair is dramatically cheaper than the £2,200–£4,000 replacement that follows if ignored. Avoid pre-2015 N20 cars without documented chain history.

Compare N20 engine prices for your F10

N63

Hot-Vee V8 Heat-Related Failures

Affected models:

F10 550i (2009–2017, N63 engine).

Typical failure mileage:

40,000–80,000 miles.

Root cause:

The N63's "hot-vee" design places the turbochargers inside the V of the engine, generating significant heat. This leads to premature failure of valve stem seals, turbo coolant lines, and the battery drain issues associated with the N63. The N63TU (2014–2017) improved some aspects but retained the hot-vee architecture.

Our Recommendation

If you own an N63-powered F10, budget for valve stem seal replacement as a preventative measure -a £500–£1,000 investment is far cheaper than the £6,000–£10,000 engine replacement that follows a failure. Monitor oil consumption and investigate any increase immediately.

S63

Crank Hub & Rod Bearings (M5)

Affected models:

F10 M5, M5 Competition (2012–2016, S63 engine).

Typical failure mileage:

30,000–60,000 miles.

Root cause:

The S63's crank hub can spin on the crankshaft, causing timing to slip and potentially catastrophic engine damage. The rod bearings can also wear prematurely, particularly on cars that have been tracked or driven hard. Both issues are well-documented in the M community.

Our Recommendation

If you own an F10 M5, budget for a crank hub fix and rod bearing replacement as preventative maintenance. A £1,500–£3,000 investment is far cheaper than the £9,000–£15,000 engine replacement that follows a failure. Use the correct oil and warm the engine properly before hard driving.
