Common Failure
The S68 is BMW's most advanced V8, but early examples have shown some issues. Oil pump failure has been reported on early G06 M60i examples. The 48V mild-hybrid system can experience battery degradation after 5-7 years. Oil consumption - a hallmark of earlier N63 engines - appears reduced but should still be monitored. A software issue causing false low oil level warnings has been documented on S68 engines.
The BMW X6 M60i is powered by the S68 4.4-litre twin-turbo V8 - BMW's most advanced hot-vee V8, featuring a 48V mild-hybrid system and M-division engineering. While significantly more robust than the earlier N63 engines it replaces, the S68 is not without its teething issues. Every rebuilt engine supplied through EnginesMarket includes upgraded components addressing the original failure point - plus a minimum 12-month unlimited mileage warranty.
Why the BMW X6 M60i S68 Loses Oil Pressure
Affected Vehicles
BMW X6 M60i (S68B44A / S68B44T0, 2023-present)
Typical Failure Mileage
20,000-40,000 miles (early examples)
Root Cause
The S68's high-performance oil pump system - while incorporating racing technology with a modified oil pump and sump system and strengthened crankshaft drive - has shown vulnerability on some early G06 M60i examples. One owner reported needing a new engine and turbos at just 28,000 miles. Oil pump failure leads to low oil pressure, bearing damage, and ultimately catastrophic engine failure if not addressed immediately.

Vehicle Value Check
Vehicle Value Check
A typical BMW X6 M60i in the UK is worth between £55,000 and £90,000 depending on condition and mileage. With a full rebuilt engine costing £7,000-£11,000 fitted, replacement cost is typically small relative to vehicle value - making engine replacement a financially viable option for most M60i owners. However, given the vehicle's high value, using a specialist with S68 experience is essential to protect your investment.
Our Recommendation
Our Recommendation
If you see any low oil pressure warning on your X6 M60i, stop driving immediately and have the oil system inspected. Early intervention can save the engine. Given the high value of the vehicle, a specialist oil pump replacement (£1,800-£3,000) is significantly cheaper than a full engine replacement. Always use the correct BMW-approved oil specification and maintain strict oil change intervals.

BMW X6 M60i Engine ReplacementFrequently Asked Questions
Question 1How much does a BMW X6 M60i engine replacement cost in the UK-
A full BMW X6 M60i engine replacement typically costs £5,500-£9,500 supply-only for a rebuilt S68B44A unit, or £7,000-£11,000 fitted by a specialist.
- Used S68B44A engines: £3,500-£5,500 depending on mileage and condition
- Reconditioned units: £4,500-£7,000
- Professional fitting adds £1,500-£2,500 to the engine cost
Question 2Is the BMW X6 M60i S68 engine reliable-
The S68 is BMW's most advanced V8, incorporating racing technology from the XM and X7 M60i. However, early examples have reported oil pump failures - one owner needed a new engine at just 28,000 miles. The S68 is significantly more robust than the earlier N63 engines it replaces, but being a relatively new engine, long-term reliability data is still emerging. Regular oil changes and monitoring of the 48V system are essential.

The most common warning signs of oil pump failure in the X6 M60i are:
- Low oil pressure warning light - stop driving immediately
- Knocking or tapping noise from the engine
- Engine running rough or misfiring
- Complete engine seizure - if oil pressure drops to zero
Question 4Is it worth replacing the engine on a BMW X6 M60i-
For an X6 M60i worth £55,000-£90,000, a £7,000-£11,000 rebuilt engine is typically good value - replacement cost is small relative to vehicle value.
- Compare replacement cost against vehicle value - replacement is viable up to approximately 70% of the car's value
- Given the vehicle's high value, specialist rebuild with warranty is the safest option
- Always factor the 12-month warranty into your replacement decision
Question 5What causes the BMW X6 M60i 48V mild-hybrid system to fail-
The 48V mild-hybrid system can fail due to:
- 48V lithium-ion battery degradation after 5-7 years (£600-£1,000 replacement)
- Starter-generator belt wear or failure
- Battery management system faults
Question 6Can I replace my BMW X6 M60i engine with a different engine-
Engine swaps to a different size or type are technically complex and rarely cost-effective for the X6 M60i:
- The S68B44A and S68B44T0 are the only engines fitted to the M60i from the factory - stick to like-for-like replacement
- Swapping to the X6 M Competition engine (S63B44C) requires different ECU, wiring, cooling, and transmission calibration
- The 48V mild-hybrid system is integrated with the engine - swapping to a non-hybrid engine is not feasible
- Insurance must be notified of any non-standard engine swap
- Our marketplace only recommends like-for-like code-matching for warranty coverage
