Hi, I am hoping someone might point me in the right direction. I own a C220 CDI SPORT ESTATE W202 AUTO and its a great car but recently when I start the car the display shows no gear position. I can move the gear selector,but will move to drive and back to reverse and thats how far it goes unless i turn the ignition off and i can move it back to park.If I do this a few times then eventually the display shows P and i can move it to D and drive off. It seems to be getting worse and have been told it could be the electronic plate?
