I have a 1996 Z3 - 1.9L and at the end of the Summer my cruise control quit working every time my car sat out in the heat or was driven after about 30 minutes or so. I have a friend that a master mechanic that worked on BMWs for years, he suggested that I replace the "brake pedal" brake light switch. I did so with no avail, still have the same problem.

Have any of you encountered this issue, and if so how was it remedied.

Any help is GREATLY appreciated.
