SMG, gears won't select
I have a problem with my 2004 Z4 3.0 SMG...
I selected sport mode, started the car and put it into reverse. The gearbox warning light came on.
After I switched the car off and started it again (not in sport mode) it was fine. I drove about 2km and returned with no problems.
Now when I put in the key, the gear selector display shows me 'FN'.
The car is in gear and will not get back into Neutral.
Does anyone know what the problem is?
And what does the 'F' mean on the display?
Any help would be greatly appreciated.
