I'm having a strange problem with my Z4M. Whenever the car has been sitting for a day or two, the axle / wheels seem to be sticking when I drive the car again for the first time. I have recently returned from a 2 week holiday and the problem was really bad - I had to rev the car hard to get it to 'unstick' and pull away. Once the car has moved it performs as normal. Any ideas? The car has just been through its inspection 1 service and nothing unusual was picked up from that.
