@ Vass - yes the card key is hot but I cannot givce advice on cruise control functions as I do not have them..It maybe that this piece of plastic and it's need to hit the microswitch on the card reader PCB has other hidden features.. Have you tried this fix yet ?
However something else I have very much noticed !!
Before this fix I had to hold in the start / stop button until the engine started.
Now I can literally tap the switch and it will hold the starter on until the engine fires up as it should do. Something I have spent ages trying to work out in the past and given up..
Another problem fixed !!
