My wife's Mini cooper convertible (2005) has just started slipping its clutch at between 3000 and 3500 RPM. Doesnt happen lower down in the rev range even in higher gears, which is a little strange....
I'm assuming that the clutch is on its way out. Am I correct? If so - whats a ballpark cost for a clutch for this car. Got an online quote from Mr Clutch for £400 fitted with a 2 year warranty - which i though was quite reasonable.
I read someonline on another forum that someone else had exactly the same problem in the the cold, when it warmed up it went away. Does this make sense to anyone at all or is this just rubbish?
Yup - I'd say the clutch could be on the way out but here's a few thoughts on your problem:
1) Have you had the clutch pedal adjustment checked? ie: is the clutch friction takeup point high up (pedal almost released) or way down low? Your mechanic should check clutch pedal adjustment first.
2) Have you had the crankshaft oil seal checked for leakage? If the seal is leaking, oil can contaminate your clutch plates which will then make the clutch slip. If this is the case - you'll need to replace the crankshaft main seal as well as the clutch.
3) Easy way to check for slipping clutch is - drive slowly in 1st gear say in a carpark or long driveway - ensure foot off the clutch. Now get on the brakes whilst you're driving slowly - keep applying some more throttle to overcome the load of the braking as you get heavier with the brakes. Just a few seconds of this and you'll have your answer.
If the clutch is good - there should be no slippage when you load up the engine using the brakes. Usually you may stall the engine or at least labour it. But if the car slows down and the engine revs start to rise with no increase in vehicle speed as you brake then the clutch is slipping for sure.
BTW - only test for a few seconds as if the clutch is slipping you will be generating enormous heat in the clutch due to the heavy load from the brakes, so keep the testing brief or you may disintegrate what could be an already failing clutch!
If the clutch is confirmed as slipping, best get it replaced promptly as if you try to drive it any distance you'll end up on the roadside with no drive in any gear and a tow truck will be needed to get you home again.
