Hi,
I have this problem with my 2012 159. I can't get the key from the dash when I turn the car off. A flashing "P" shows. Probably a dumb question but thought someone may know. I can't ring the distributors as it's Anzac day.
Cheers
Andy
change all the gears quite firmly and then try again
as in move into gear and out and put in P again if its an auto
