BMW X7 M60i Engine Replacement Compare Prices & Get Quotes

A full BMW X7 M60i engine replacement typically costs £7,500-£12,000 supply-only for a rebuilt S68B44 unit, or £8,500-£13,000 fitted by a specialist. Used engines start from £4,500, while reconditioned units typically cost £6,500-£9,500.

• Prices reflect the hot-vee V8 complexity - specialist rebuilders only
• Professional fitting adds £1,000-£2,000 including ECU coding and 48V system calibration
• Rebuilt units include upgraded piston rings and cooling components
• 12-month unlimited-mileage warranty on all rebuilt engines

The S68B44 V8 has three main areas of reported concern: oil consumption (piston rings and valve stem seals), turbocharger wastegate rattle and boost loss, and cooling system leaks (expansion tank and crossover pipes).

• Oil consumption typically appears from 30,000-80,000 miles
• Wastegate rattle on deceleration indicates actuator wear
• Low coolant warnings point to cooling system leaks
• The hot-vee design concentrates heat - regular maintenance is critical

The S68B44 is BMW's latest hot-vee V8, building on lessons from the N63 and S63. It's more robust than its predecessors, with closed-deck blocks and reinforced internals. With proper maintenance - strict oil change intervals and proactive cooling system care - S68 engines can exceed 100,000-150,000 miles.

• Use BMW Longlife-04 oil and change every 8,000-10,000 miles
• Oil consumption and cooling system are the main wear items
• 48V mild-hybrid system requires specialist maintenance
• The S68 is a significant improvement over earlier N63 engines

For a 2022-2024 X7 M60i worth £73,000-£95,000, a £7,500-£12,000 rebuilt S68B44 engine represents excellent value - typically 10-18% of the vehicle's value.

• Replacement cost is small relative to vehicle value
• If body, gearbox, and chassis are sound, a rebuilt engine adds years of life
• Used engine (£4,500-£7,000) is the budget option for short-term ownership
• Rebuilt engine (£7,500-£12,000) offers warranty and peace of mind

The M60i (2022-present) replaced the M50i (2019-2022). Both use 4.4-litre twin-turbo V8s, but the M60i features the newer S68B44 engine with 48V mild-hybrid assistance, closed-deck block, and improved thermal management.

• M60i: S68B44, 530hp, 48V mild-hybrid, 4.7s 0-62mph
• M50i: N63B44T3, 523hp, no mild-hybrid
• M60i has improved fuel economy and smoother stop-start
• Engine codes are not interchangeable - always match the correct code

Engine swaps to a different size or fuel type are technically complex and rarely cost-effective on the G07 X7. Stick to like-for-like replacement using the correct S68B44A or S68B44T0 engine code for your M60i.

• ECU, wiring loom, fuel system, and exhaust all differ between petrol and diesel
• 48V mild-hybrid system is integrated with the engine
• Transmission requires specific fluid (ZF Lifeguard Hybrid 2)
• Insurance must be notified of any non-standard engine swap
