My cruise on my 300E only works when I'm on an incline. It's the weirdest thing, if I'm going uphill or down hill it will work, on flat ground it's just dead.

I haven't had the time or inclination to hunt down the problem yet. I believe it could be a problem with the control block. If you remove your glove box toward the center of the car you'll see a big box with a whole mess of vacuum lines coming out of it. I saw it when I was replacing the fan for the cabin temperature sensor.

Good luck!
