Mini Countryman: R60 Cooper D / SD N47 Diesel Rear Timing Chain Catastrophic Failure

The BMW N47 2.0-litre diesel engine used in R60 Cooper D and SD Countryman models is subject to a catastrophic and thoroughly documented timing chain failure. Uniquely, the N47's timing chain is mounted at the rear of the engine (firewall side), requiring the engine to be removed for access. The chain tensioner and guide fail, allowing the chain to skip or snap, destroying the engine. The rear-mounted chain makes preventive replacement extremely expensive, and many owners only discover the issue when the engine fails. This fault has been the subject of class action proceedings in the UK. Any N47 Countryman over 100,000 km without documented chain replacement must be treated as imminently at risk.

• Rattling from the rear of the engine (sounds like it comes from the firewall side) on cold start
• Rattle that does not clear after warm-up or worsens progressively
• Engine vibration at idle that increases over time
• Sudden catastrophic power loss and engine stopping if chain fails
• Engine cranks but does not start after chain failure

Cold-start and listen carefully for rattle emanating from the rear (firewall) side of the engine. Ask explicitly whether the N47 timing chain has been replaced - any example over 100,000 km without documentation is very high risk. Factor full chain replacement into purchase price if history is absent. Avoid examples with unknown service records entirely. Have a specialist perform a pre-purchase compression test.

$5,000 to $18,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the N47 timing chain, tensioner, and guides been replaced, and at what mileage?”
• “Any rattling noise on cold start, particularly from the rear of the engine?”
• “Can you provide full dealer or specialist service records for this vehicle?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
