Common Failure
Rod bearing wear is a well-documented issue on early S63 engines. Timing chain tensioner failure and turbocharger issues also reported.
The BMW X5 M's S63 4.4-litre twin-turbo V8 is a masterpiece of M division engineering, delivering brutal performance and a soundtrack to match. However, like any high-output engine, it has well-documented weaknesses - particularly rod bearing wear, timing chain tensioner failure, and turbocharger issues. Every rebuilt S63 engine supplied through EnginesMarket includes upgraded components addressing the original failure points - plus a minimum 12-month unlimited mileage warranty.
Why the BMW X5 M's S63 V8 Fails Prematurely
Affected Vehicles
BMW X5 M (E70 2009-2013, F85 2014-2018, S63B44, S63B44T2)
Typical Failure Mileage
60,000-100,000 miles
Root Cause
The S63 engine's rod bearings are subjected to extreme loads, particularly during high-RPM use. Insufficient lubrication, oil degradation, or manufacturing tolerances can cause premature wear. If ignored, bearing failure leads to catastrophic engine seizure - a £10,000+ repair bill.

Vehicle Value Check
Vehicle Value Check
A typical BMW X5 M is worth £18,000-£80,000 depending on generation, mileage, and condition (`[THIRD-PARTY]` - Auto Trader market observation). For an E70 X5 M worth £18,000-£30,000, a rebuilt engine at £10,000-£15,000 represents 35-50% of the vehicle's value - evaluate body, gearbox, and interior condition carefully. For F85 and F95 examples worth £35,000+, replacement is generally viable. Sub-£20,000 E70 examples should be assessed for scrap value first.
Our Recommendation
Our Recommendation
On any S63-powered X5 M approaching 60,000 miles, preventative rod bearing replacement at a specialist is the single best investment you can make. It's far cheaper than a full engine replacement and adds years of life to the engine. If you hear a knocking noise from the bottom end, stop driving immediately - continued use will destroy the engine.

BMW X5 M Engine ReplacementFrequently Asked Questions
Question 1How much does a BMW X5 M engine replacement cost in the UK-
A BMW X5 M engine replacement typically costs £6,000-£14,000 supply-only for rebuilt units, or £10,000-£18,000 fitted by a specialist. The S63 V8 is a complex, high-performance engine requiring specialist knowledge.
- Used S63B44 engines: £5,000-£9,000 supply-only
- Reconditioned units: £8,000-£14,000 supply-only
- Professional fitting adds £1,500-£3,000 depending on workshop location
- Dealership replacement quotes often exceed £20,000
Question 2Is the BMW X5 M S63 engine reliable-
The S63 is a remarkable engine when properly maintained, but it has well-documented weaknesses. Early versions (S63B44) are prone to rod bearing wear, timing chain tensioner failure, and turbocharger issues. Later revisions (S63TU, S63TU2, S63TU4) addressed many of these concerns.
- Rod bearings typically need attention between 60,000-100,000 miles
- Frequent oil changes (every 5,000-6,000 miles) are critical
- Cooling system components should be inspected regularly
- Later F95-generation engines are significantly more robust
Question 3What are the signs of rod bearing failure in a BMW X5 M-
The most common warning signs are a knocking noise from the bottom end (especially on cold start), metallic debris in the oil, low oil pressure warnings, and in severe cases, engine seizure.
- Knocking noise that increases with RPM is the most serious warning sign
- Oil analysis can detect bearing material in the oil before failure
- Ignoring rod bearing noise will destroy the engine
- Preventative bearing replacement at 60,000 miles is strongly recommended
Question 4Is it worth replacing the engine on a high-mileage BMW X5 M-
For an E70 X5 M worth £18,000-£30,000, a rebuilt S63 at £10,000-£15,000 can make financial sense if the body, gearbox, and interior are in excellent condition. For F85 and F95 examples worth £35,000+, replacement is generally viable.
- Compare replacement cost against vehicle value - specialist advice: replacement viable up to 70% of car's value
- Low-mileage, well-maintained examples justify higher investment
- Factor 12-month warranty into replacement decision
- Always get a full vehicle inspection before committing to major work
Question 5What are the differences between the E70, F85 and F95 X5 M engines-
Each generation uses a different iteration of the S63 V8:
- E70 (2009-2013): S63B44, 555hp, first-generation M V8
- F85 (2014-2018): S63B44T2, 575hp, Valvetronic added
- F95 (2020-present): S63B44B, 600-625hp, latest TU4 version
Question 6Should I buy a used or rebuilt engine for my BMW X5 M-
A rebuilt engine with upgraded components - particularly rod bearings and timing chain components - offers significantly better long-term reliability than a used engine of unknown provenance. For a high-performance M car, the additional cost of a rebuilt unit is typically justified.
- Used engines: lower upfront cost but unknown history and no warranty
- Rebuilt engines: upgraded components, 12-month warranty, known quality
- Reconditioned engines: mid-range option with some new components
- For X5 M ownership, rebuilt is strongly recommended for peace of mind
