Sorry Leanie, might be time to call a tow truck.  I am sure they have ways to load a car with locked wheels.  Make sure they use the tow hook when pulling the car...

I suspect its something electronic causing the problems - either the valve body in the transmission or maybe the EGS controller.  It may be as simple as updating the software, or it could be something failed....  best to have the dealer look at it.

Thanks Ken:  Tried that but still could not budge out of park.  there is actually a tool in the tool kit thst hooks on to s yellow piece of plastic under the boot.  I pulled it out and it dropped into no mans land.  Really frustrated. 

'good luck' was from me....
Ken : )

Slightly worrying that the owner manual says "good luck" !

Low battery? 

Here is something from the owners manual that might help:

Overriding the selector lever lock
Should the selector lever refuse to move out of
position P although the button on the selector
lever is pressed, the selector lever lock can be
overridden:
1. Unclip the sleeve of the selector lever.
2. Pull the sleeve up over the selector lever
until the sleeve is inside out. Disconnect the
cable connector if necessary.
3. Depress the brake.
4. Pull up the loop on the passenger side while
at the same time moving the selector lever
into the desired position.

good luck
Ken

Tried to start 2008 cooper S and when I pushed the starter button the windshield wipers came on and the Gear icon with ! Mark shows on dash.  Can't get out of gear to tow either
