Why the MINI Countryman Cooper S / Cooper S ALL4 N18B16A Wears Prematurely
Affected Vehicles
MINI Countryman Cooper S / Cooper S ALL4 (N18B16A, 2010-2016)
Typical Failure Mileage
70,000-100,000 miles
Root Cause
The original timing chain tensioner can lose hydraulic pressure over time, allowing the chain to stretch and slap against the plastic guides. This creates a rattling noise on cold starts and can eventually lead to catastrophic internal engine damage if the chain jumps.

Vehicle Value Check
Vehicle Value Check
A typical R60 MINI Countryman Cooper S / Cooper S ALL4 (2010-2016) is currently valued between £3,000 and £7,000 depending on condition and mileage [THIRD-PARTY]. An F60 model (2017-2023) typically ranges from £10,000 to £20,000+ [THIRD-PARTY]. If your R60 vehicle is worth under £5,000, a full rebuilt engine may approach the car's total value, making a quality used engine or preventative repair the more financially sensible route. For F60 models, a reconditioned or rebuilt engine is strongly justified to protect the vehicle's significant residual value.
Our Recommendation
Our Recommendation
For N18-equipped MINI Countryman Cooper S / Cooper S ALL4 models, a preventative timing chain replacement is critical if it has not been done already. If catastrophic failure has already occurred, a full replacement with a rebuilt unit featuring upgraded components is the only reliable long-term solution.
Don't Let Engine Failure Write Off Your MINI Countryman Cooper S / Cooper S ALL4
Whether you are dealing with the notorious N18 timing chain rattle or a B48 cooling system issue, replacing your engine with a rebuilt unit from EnginesMarket ensures the original weak points are addressed with upgraded components. You get a minimum 12-month unlimited-mileage warranty, nationwide delivery, and prices that are significantly lower than main dealer premiums.

MINI Countryman Cooper S / Cooper S ALL4 Engine ReplacementFrequently Asked Questions
Question 1How much does a MINI Countryman Cooper S / Cooper S ALL4 engine replacement cost-
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.
Question 2What are the signs of timing chain failure in a MINI Countryman Cooper S / Cooper S ALL4-
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.
Question 3Does the ALL4 all-wheel-drive system affect engine replacement cost or time-
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.
Question 4Is it worth replacing the engine in a 2010-2016 MINI Countryman Cooper S / Cooper S ALL4-
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.
Question 5What is the difference between the N18 and B48 engines in the MINI Countryman Cooper S / Cooper S ALL4-
The N18 (2010-2016) is a 1.6L turbocharged 4-cylinder engine producing 184 hp, known for its punchy delivery but also its timing chain vulnerabilities. The B48 (2017-2023) is a 2.0L turbocharged 4-cylinder engine producing 192 hp. The B48 features a rear-mounted timing chain, improved thermal management, and significantly better long-term reliability.
- The B48 offers more torque, better fuel efficiency, and lower emissions.
- The N18 requires strict preventative maintenance to avoid catastrophic failure.
- Both engines benefit from upgraded rebuilt components addressing known weaknesses.
