Cruise control is not working. I checked the fuse and it is fine. Any ideas on how I should trouble shoot this one?

Hi Mark, I had similar problem on my e46 compact. There are probably many possible causes. Mine was a faulty wheel speed sensor. You will need to read the fault codes. There is a brilliant mini bluetooth OBD2 device that simply plugs into the cars OBD2 socket and links via bluetooth to your smartphone or tablet. A free app from the Google Play Store called Torque Lite will the talk to the vehicle computer and tell you in plain English what the fault codes stored are and what they mean. In my case the rear offside wheel sensor had failed which also caused the ABS to become inactive and also the ASC light to come on. Oh BTW, the mini bluetooth OBD2 device is about a tenner on ebay. The OBD2 socket is located above the drivers knee and is similar is size and shape to a scart socket. I think the socket has a dust cover but mine had been broken off already
Best of luck. Brian
