MINI Countryman Cooper S / Cooper S ALL4 Engine Replacement Compare Prices & Get Quotes

The cost to replace a MINI Countryman Cooper S / Cooper S ALL4 engine varies by generation and condition. Used engines typically range from £1,200 to £2,200, while reconditioned units cost between £2,200 and £3,500. A fully rebuilt engine with upgraded components and a 12-month warranty generally ranges from £3,000 to £4,800, excluding labour.

• Used engines are the most budget-friendly but carry higher risk.
• Reconditioned engines offer a balance of reliability and cost.
• Rebuilt engines provide the longest lifespan and best warranty coverage.

The most common early warning sign is a rattling or metallic ticking noise from the engine bay, particularly during a cold start. Other symptoms include the check engine light illuminating, rough idling, loss of power, or a "death rattle" that worsens with engine speed.

• Do not ignore a cold-start rattle; it indicates tensioner wear.
• Continuing to drive can cause the chain to jump, leading to catastrophic valve damage.
• Immediate inspection by a MINI specialist is strongly advised.

Yes, the ALL4 system adds a small amount of complexity to the replacement process. Removing and reinstalling the rear driveshaft and transfer case typically adds around 1 hour to the specialist labour time compared to a front-wheel-drive Cooper S. However, the core engine supply costs remain identical.

• Specialists factor this into their itemised quotes transparently.
• The ALL4 system itself is robust and rarely requires replacement alongside the engine.
• Always ensure the specialist has experience with MINI ALL4 drivetrains.

It depends on the vehicle's overall condition and current market value, which typically ranges from £3,000 to £7,000 for this era. If the rest of the car is in excellent condition with low mileage, a reconditioned engine can extend its life reliably.

• Evaluate the car's bodywork, suspension, and service history first.
• A used engine is often the most financially viable option for lower-value examples.
• Always get multiple quotes to ensure you are getting a fair market price.
