Hi Alex I forgot to mention that your car will have a Torsen (TORque SENsing) type of LSD. These units are a far better type for road driving than the locking-cloutch type, but they reduce the ease with which the car can be drifted. They operate by a clever gear train - see Wikipedia for details - w...

Re: Clattering noise from the front.

Does your 2.2 have an engine-driven fan? Can't remember if they do, as the later BMW engines rely on the air con condensor fan. If it does have a mechanical fan, it may be that the viscous coupling is on its last legs - 60 to 70,000 miles is a pretty usual life for these couplings. It is easy enough...

If your gear lever is not made of metal, what is it made from - perhaps resin, like the clutch pedal? In this case you would need to get hold of an older type of lever.

Re: Z3 gear change?

The usual cause is clutch drag, caused by either a worn-out clutch or (more likely) the need for re-greasing of the splines on the gearbox input shaft and the clutch hub.

Bleeding the clutch slave cylinder and changing the oil also help.
