Mini Coopers 2007-2008 (R56) – Engine Noise - Timing Chain Tensioner Failure – N12 and N14 Engines
We’ve seen a surprising number of Coopers, two in the last week alone, come in with a knocking noise in the engine, this has been dubbed the “Death Rattle”. Should you hear this noise on your car, DO NOT IGNORE it, we have a car in the workshop today in which the timing chain has failed, damaging the engine. Mini has released a service kit addressing this problem, the key thing to correct it BEFORE failure. If you have this problem, call us right away for help at (207) 882-9969.
Sounds – Cold and Warm
This noise is especially pronounced when the engine is cold, sounding almost like a diesel engine with a rapping or knocking noise between 1500 and 2000 PRM. When the car warms up, the noise will abate to a degree, but in advanced cases still be present even with a warm engine. We’ve had this occur on cars with as little as 12K on the odometer, so this is not a high mileage problem.
Prevention Is Easy
The best thing you can do to PREVENT this problem in the first place is to change your engine oil and filter every 7,500 miles, not the Mini norm of 15,000 miles, always use a high quality synthetic engine oil and factory filter.
For cars which are in warranty, we can work with Mini to confirm coverage for this fault, for cars outside of new car warranty, we have the ability to correct this for once and all. Mini has released a service kit addressing this problem, the key thing to correct it BEFORE failure. If you have this problem, call us right away, before failure. Rest assured that we have the tools and experience to put the fun back in your Mini!
