you have a S2 correct that would mean you had hte keyless option. if so tey would have used the OE actuator. I would backtrack where it was tied in and check for a loose connection. if you cnat win go see keith and get him to sort it out.
think CAM= vision. though would would have went to a CAM dealer to get it fitted. take it back to one thats in your area (they are a national alliance.) and tell them what is wrong.
do a mold of the tyre and then invert the wheel so you have more space. I would make the whole thing a plug that way you have a flat floor and still have the spare tyre.
there will be more after I get through.. kaz gave me a big stack of cards. seeing as I work on a lot of these cars I figure a few more in the crowd couldnt hurt.
welcome!
your car sounds like several I have worked on. mainly 32s with the front literally half hanging off. if you have a cut and shut - run away.. it will cause you more greif than you will ever want.
