I have only had my car since April and the cruise control worked fine then. On a trip to an autox I noticed while I could turn on the CC when I tried to set the speed it would not take the set. This is nota big deal for me but I would like to have it working. I hope I can get some guidance as to what to look for,

Thanks

 

It's usually either the cruise control stalk, the clutch switch, or brake switch. A scan tool is going to be the easiest way to figure it out.

 

It was the the clutch switch. Thanks

 

Glad you got it figured out, did you end up using a scan tool then ?

 

I first did my onw visual inspection and I noticed a crack in the switch. I then chose to take the car to my Porsche mech to be sure and he confirmed the switch failure.

 

Wow, I don't even know if my cruise control works and I've had the car over two years!
