2004 760li Active cruise not working

[jaredstewart85]

Have had an issue with my cruise control not working for a few months now and haven't been able to figure it out. Car is a 760li with ACC. When i try to activate cruise all i get is a couple of small dashes in the instrument cluster where it would normally show your set speed. At this time all i have to scan car with is a snapon scanner but its limited as to what i can access apparently. If anyone would have any ideas they would be greatly appreciated. I was leaning towards the radar module in the front bumper as it sounds like a more common failure point but would like to diagnose it to see if thats the problem before throwing parts blindly.

You're going to have to have it scanned with a real BMW scan tool that can access the ACC module. Please don't waste your money throwing parts at it without a proper diagnosis.

Thats what i was thinking.... Any idea if there is a way for a person to scan acc module himself with non bmw software? I'm about 4 hrs away from closest bmw dealer..

I use ISTA because it's dealer software. That's the only thing I have experience with.
