Mini John Cooper Works R56 buying guide
The factory John Cooper Works version of the second BMW Mini, on sale from 2008 until the F56 arrived in 2014, with a 211bhp turbocharged 1.6, bigger brakes and an electronic limited-slip function. It shares the Cooper S engine's known points, most of which have a check you can do at the viewing.
The versions
- 1.6 turbo four-cylinder with a revised cylinder head, 211bhp and 260Nm, with 20Nm extra in Sport mode
- Getrag six-speed manual only
- DSC and DTC stability control with EDLC, described as an electronic limited-slip differential, which stays active with DSC switched off
- Genuine cars have a Sport button, bigger brakes, an upgraded stereo and piano black interior trim
What to check on a R56 JCW
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
Is it a genuine JCW
What to look for: Look for the Sport button by the gear lever, the larger brakes behind the wheels, the upgraded stereo and the piano black interior trim. Check the V5C and the service book describe the car as a John Cooper Works.
Why it matters: Many 184bhp Cooper S cars were upgraded to 211bhp with a dealer JCW kit or tuning, and they look similar. A converted Cooper S lacks the factory car's bigger brakes and other parts, so it isn't the same car.
Timing chain rattle from cold
What to look for: Ask for the engine not to be started before you arrive. During the first minute of a cold start, listen at the front of the engine for a brushing noise or rattle. Check the dipstick, and ask for paperwork showing a timing chain or tensioner replacement.
Why it matters: The timing chain tensioner is the known weak spot of this engine family, and cars before 2011 are most at risk; a revised tensioner with a longer plunger and stronger spring became standard in 2011. These engines can use around a litre of oil per 1,000 miles, and running low makes the problem worse.
Water pump recall and coolant
What to look for: Ask a Mini dealer to confirm against the VIN that recall work on the water pump has been completed on a car built from 2008 to 2011. Check the coolant level and look for crusty coolant deposits around the engine.
Why it matters: The water pump's circuit board can fail on 2007 to 2011 cars, causing overheating and a risk of fire, and was the subject of a recall.
