Another engine rattle at idle
- Thread starter ChillZ4
- Start date
olice:Thrust bearing is unloaded and the inner and outer parts rattle against each other (ie, the part the clutch lever arm forks touch is seperate to the inner part that touches/presses the rotating clutch pressure plate springs to open the clutch) these two parts are seperated by a bearing which wears and gets rattly.
When you press the clutch the forks push on the outer, and the pressure plate springs press on the inner, and this 'tightens' the bearing up so it's not rattling off it's normal rotating axis... they will last for ages like this, but of course it is wearing and it will eventually fail (even a new one is starting to fail as soon as it is fitted though)
If you have to get it done, may as well do a clutch kit while you are in there...
What mileage/age is the car?

Hmmm, seems early for that kinda thing, but as I always say, this is why cars come with warranties, because there are odd parts that do fail prematurely out of spec.
I'd just see if it gets better or worse, and as always compare it to another one to see if it is the same... the tranny in the Z4 is quite 'noticeable' compared to more normal layout cars...
