I did this yesterday. You have to remove the sync screen. Behind the screen is a coverplate that you have to remove (just pull up). Then you will see 3 small bolts, unscrew these and press a plastic tab close to one of these bolts and pull screen upwards. You can now reach behind the dash and unplug the starterbutton (press tab and pull on the electrical plug). After that press the tabs on the sides of the starterbutton and push the starterbutton out of the dash and fit the new starterbutton. Bit fiddly if your hands are to big.Can this be retro-fitted to the PE easy enough?
