On the 2007-2013 MINI Cooper, the R56 Cooper's N12 and N16 engines suffer from premature timing chain tensioner and guide rail failure. The plastic chain guides deteriorate, causing chain slack that leads to rough running, rattling on startup, and potential catastrophic engine damage if the chain jumps timing.

This issue also affects: BMW 1 Series, BMW 2 Series Active Tourer, BMW 3 Series

Common Symptoms

  • Rattling noise on cold start
  • Check engine light
  • Rough idle
  • Loss of power
  • Engine misfire

How to Fix

Replace timing chain, tensioner, and guide rails. Use updated BMW/MINI parts with revised guide rail material. The entire front of the engine must come apart. Recommend replacing water pump and thermostat at the same time.

On the 2007-2016 MINI Cooper, the valve cover gasket on N12/N16/N18 engines hardens and leaks oil onto the exhaust manifold, creating a burning oil smell. VANOS solenoid seals also leak, causing oil to pool around the solenoids and potentially cause misfires.

This issue also affects: BMW 1 Series, BMW 4 Series, BMW 7 Series

Common Symptoms

  • Burning oil smell
  • Oil on exhaust manifold
  • Visible oil leak from valve cover
  • Check engine light
  • Rough idle

How to Fix

Replace valve cover gasket (the cover and gasket are one unit on these engines) and VANOS solenoid O-rings. Clean oil residue from exhaust manifold.

On the 2007-2016 MINI Cooper, both R56 and early F56 Coopers use an electric thermostat housing and electric water pump that are prone to premature failure. The thermostat housing cracks causing coolant leaks, and the water pump impeller can fail leading to overheating.

This issue also affects: BMW M3, BMW X1, BMW X3

Common Symptoms

  • Coolant warning light
  • Overheating
  • Coolant puddle under car
  • Heater blowing cold air
  • Temperature gauge fluctuation

How to Fix

Replace thermostat housing assembly and/or electric water pump. Use updated MINI parts. The thermostat housing is on the front of the engine and relatively accessible. Water pump is belt-driven on N12/N16, electric on newer B38/B48.

On the 2007-2013 MINI Cooper, bMW of North America recalled 2007-2013 MINI Hardtop 2-Door Cooper models under NHTSA campaign 23V337000, filed under the electrical system component. On affected cars, the electronic control module located in the driver's side footwell area can develop a fault. NHTSA states the consequence plainly: an electrical short-circuit can increase the risk of a fire. Coverage is limited by geography rather than by trim or options — the recall applies to MINI Hardtop 2-Door Cooper vehicles that were sold in, or have ever been registered in, Alaska, Colorado, Connecticut, Delaware, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Dakota, Ohio, Pennsylvania, Rhode Island, South Dakota, Utah, Vermont, Virginia, West Virginia, Washington D.C., and Wisconsin. That the prescribed inspection includes the sunroof drains alongside the footwell area and the module itself points to the footwell environment as central to the defect. The campaign as a whole covers 97,933 vehicles across every MINI model and year included in it — that figure is campaign-wide and is not a count of Cooper Hardtops specifically. Owner notification letters for this recall were mailed on May 13, 2024, so a Hardtop Cooper bought used may never have had the letter reach its current owner.

How to Fix

Take the car to an authorized MINI dealer — recall work is free of charge, regardless of the vehicle's age or mileage. The dealer will inspect the sunroof drains, the interior footwell area, and the footwell electronic control module (FRM), and will replace certain components depending on what that inspection turns up, so the exact repair varies car to car. Because this campaign is limited to specific states, confirm applicability by entering your VIN at nhtsa.gov/recalls, which will show whether recall 23V337000 is open on your particular Hardtop Cooper. For questions about scheduling or parts availability, BMW customer service can be reached at 1-866-825-1525.
