BMW M5 Engine Problems
What It Costs to Fix & When Replacement Makes Sense
The BMW M5’s reputation for high‑performance engineering comes with well‑documented engine vulnerabilities, particularly in the V10 S85 and twin‑turbo V8 S63 families. These two engine families dominate replacement demand, with rod bearing failures in the E60 generation and timing chain / oil pump issues in the F10 and F90 cars accounting for the majority of 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 failures, what repair (or replacement) actually costs through dealers versus specialists, and when it makes financial sense to act.
Every rebuilt engine includes a minimum 12-month unlimited mileage warranty.
1. BMW M5 S85 V10 Rod Bearing Failure
Why E60 M5 Engines Fail Catastrophically
Affected Models
BMW M5 E60, M5 E61 Touring (2005‑2010, S85B50)
Typical Failure Mileage
60,000 - 85,000 miles
Root Cause
Insufficient rod bearing clearance from the factory, leading to oil film breakdown under hard cornering or extended high‑RPM running. Bearings eventually spin, seize to the crankshaft, and cause bottom‑end destruction.
Repair Options & Estimated Costs (UK ranges)
| Repair Tier | Dealer Price | Specialist Price | What It Involves | Longevity / Suitability |
|---|---|---|---|---|
Preventative - Rod Bearing Replacement Minor | £2,800 - £4,000 | £1,800 - £2,500 | Replace rod bearings with aftermarket uprated units (e.g., ACL or WPC‑treated), new bolts, oil pump, sump gasket | Adds 60,000‑80,000 miles of safe life if done before any knocking noise or low oil pressure warning |
Full Replacement - Rebuilt S85 Engine Best Value | £12,000 - £18,000 | £7,000 - £12,000 | Supply & fit of fully rebuilt S85B50 with uprated rod bearings, new timing chain, VANOS overhaul, bench tested | New engine life with upgraded components; 12‑month unlimited mileage warranty |
Our Recommendation
Best next step for bmw m5 s85 v10 rod bearing failure
On an E60 M5 worth £15,000‑£25,000, preventative bearing replacement is the single best investment you can make. If you hear bottom‑end knock or see low oil pressure warnings, the engine is already terminal - replacement is the only safe option. Do not attempt a “half rebuild” on a spun bearing S85.
Don't Let Engine Failure Write Off Your BMW M5
Whether you own an E60 V10 with failing rod bearings, an F90 V8 with oil pump failure, or an E39 with VANOS issues, EngineMarket makes it simple to compare prices from trusted UK BMW M5 specialists. Every rebuilt engine supplied through our network includes upgraded components that address the original failure point - not a like‑for‑like replacement waiting to fail again. With a minimum 12‑month unlimited mileage warranty and nationwide delivery & fitting options, you can get back on the road without paying main dealer premiums.

FAQ
BMW M5 Engine ReplacementFrequently Asked Questions
Question 1
How reliable is the BMW M5 S85 V10 engine and when should I replace the rod bearings?
The S85 V10 is notorious for rod bearing failure, with preventative replacement strongly recommended between 60,000-80,000 miles. A well-maintained example with bearings done can easily surpass 150,000 miles.
Key points
- • Rod bearing failure typically occurs between 60,000-85,000 miles if not addressed
- • Updated BMW bearings (2011+) use harder materials but may damage crankshafts when they fail
- • Aftermarket bearings (WPC-treated or BE Bearings) offer better clearance and friction reduction
- • A 153,000-mile E60 M5 with replaced rod bearings still made 507hp on the dyno
- • Frequent oil analysis is recommended, though newer bearings don't show wear through copper/lead traces
Question 2
What causes the BMW M5 S63 timing chain to fail and how much does replacement cost?
The S63 V8's plastic timing chain guides become brittle with heat and mileage, typically failing between 70,000-100,000 miles. Specialist replacement costs £2,200-£3,200 versus dealer prices of £3,500-£5,000.
Key points
- • Timing chain rattle on cold start is the earliest warning sign
- • If the chain jumps or snaps, valves contact pistons - engine is terminal
- • The S63B44 (F10) and S63B44T2 (F10 Competition) are equally vulnerable
- • Preventive guide replacement adds 60,000-80,000 miles of reliable service
- • Full rebuilt S63 engine costs £7,500-£13,000 supply & fit from specialists
Question 3
Is the BMW M5 E39 S62 V8 reliable and what are its common problems?
The E39 M5's 4.9-litre S62 is considered one of BMW's most reliable M engines, but VANOS seal failure is almost guaranteed and causes a distinctive "growling" noise at idle that drives replacement decisions.
Key points
- • VANOS solenoid seals harden and leak oil pressure - very common from 60,000 miles
- • Symptoms include rough idle, growling noise, hesitation on acceleration
- • Camshaft position sensors and MAF sensors also fail, triggering check engine lights
- • M-specific parts are expensive - water pumps cost £250, thermostats £70
- • A well-maintained S62 can exceed 150,000 miles with proper VANOS maintenance
Question 4
Where is the engine number located on a BMW M5 and how do I find my engine code?
The engine number is typically stamped on the engine block near the thermostat housing or oil filter housing. For accurate identification, use your registration number above - we'll query DVLA and return your exact engine code instantly.
Key points
- • E39 M5 engine number location requires removing the thermostat housing to access
- • On modern M5s (F10/F90), the engine code is on a label visible from above near the oil filter housing
- • Engine code format examples: S85B50 (E60), S63B44T4 (F90), S62B50 (E39)
- • Using your registration is far simpler than finding the physical stamp
- • DVLA database includes exact engine code for every UK-registered M5
Question 5
What is the average lifespan of a BMW M5 engine and can it reach 200,000 miles?
The average BMW M5 lasts approximately 88,000 miles, with a 0% probability of reaching 200,000 miles according to reliability data. However, this data averages all M5 generations - an E39 with VANOS maintenance will outlast an E60 with neglected bearings.
Key points
- • Average BMW M5 lifespan: 87,764 miles across all generations
- • Average miles driven per year: 7,341 for M5 owners
- • 200,000-mile M5s are extremely rare - requires meticulous maintenance and proactive bearing replacement
- • E39 S62 and E34 S38 engines are the most likely to exceed 150,000 miles with proper care
- • E60 S85 V10s that survive past 100,000 miles typically had rod bearings replaced twice
Question 6
What oil does a BMW M5 use and how often should I change it?
M5 engines from 2001-2013 require 10W-60 synthetic oil, specifically formulated for high-performance M engines. Change intervals should not exceed 8,000 miles or annually - many specialists recommend 5,000-6,000 miles for the S85 V10.
Key points
- • Genuine BMW M TwinPower Turbo 10W60 is the factory-specified oil for 2001-2013 M5s
- • Some specialists prefer Red Line 15W50 for better sheer resistance and bearing protection
- • S85 V10 engines are particularly sensitive to oil quality and level - check monthly
- • The latest Shell-produced BMW 10W60 prioritises emissions over wear protection
- • Short oil change intervals (5,000-6,000 miles) are cheap insurance for rod bearing health
Question 7
How much does a BMW M5 engine replacement cost in the UK?
BMW M5 engine replacement costs vary dramatically by generation - from £6,000-£11,000 for an E39 S62 to £10,000-£22,000 for an F90 M5 CS. Specialist prices are typically 30-40% lower than main dealer rates.
Key points
- • E39 M5 (S62): rebuilt supply only £6,000-£11,000
- • E60 M5 (S85 V10): rebuilt supply only £7,000-£14,000
- • F10 M5 (S63): rebuilt supply only £6,000-£13,000
- • F90 M5 (S63B44T4): rebuilt supply only £7,000-£22,000 depending on variant
- • Supply & fit adds £600-£1,200 depending on generation complexity
Question 8
Which BMW M5 generation has the most reliable engine and which should I avoid?
The E39 M5's S62 V8 is widely considered the most reliable M5 engine when VANOS seals are maintained. The E60 M5's S85 V10 is the least reliable - rod bearing failure is almost guaranteed without preventative replacement before 80,000 miles.
Key points
- • E39 M5 (S62): Most reliable, but VANOS seals need replacement as maintenance
- • E34 M5 (S38): Very reliable straight-six, but timing chain tensioner wears
- • F90 M5 (S63B44T4): Modern reliability is good, but oil pump drive failures occur
- • E60 M5 (S85): Most problematic - factor in £1,800-£2,500 for bearings every 60k-80k miles
- • E28 M5 (M88/3): Classic reliability is good, but parts are increasingly rare and expensive
Question 9
Can I swap a different engine into my BMW M5 if the original fails?
Engine swaps are technically possible but rarely cost-effective. The M5's electronics, gearbox, and subframes are tightly integrated with its specific engine code. A rebuilt original engine is almost always the smarter financial decision.
Key points
- • ECU, DME, and immobiliser systems are coded to the original engine code
- • Gearbox compatibility (SMG, DCT, or M Steptronic) is engine-specific
- • Subframe and mounts differ across generations - not a bolt-in process
- • Specialist fabrication and custom ECU tuning adds thousands to the bill
- • Resale value drops significantly with a non-original engine
Question 10
Is it worth replacing the engine in an older BMW M5 like an E39 or E60?
Yes, if the chassis and body are in excellent condition. E39 M5s are appreciating assets, and E60 V10s are future classics. Spending £6,000-£14,000 on a rebuilt engine makes financial sense when the car's value exceeds £15,000-£20,000.
Key points
- • E39 M5 values are rising - good examples now sell for £20,000-£35,000
- • E60 M5s have bottomed out and are entering classic status - values are climbing
- • A quality rebuilt engine with upgraded bearings adds £3,000-£5,000 to resale value
- • Cheaper to replace the engine than to buy another M5 of the same generation
- • Use a specialist rebuild with upgraded components - not a used engine with unknown history
