I just had a small key issue which might help others. In my 2004 auto 2.5D The key has been reluctant to come out of the ignition on switch off. Dealer wanted £85 just to look! The dash tells me the box is in neutral, but the screen says select neutral to remove key! Grrrrrrrrrrrr! Hang on, the button in the side of the selector lever is sticking in the in position, I wonder if a little lubricant will help? One squirt of juice and its working fine! Fingers crossed though.
