Where is the fun in that..
I'm an engineer and would like to be able to prove to the guys at BMW that their sensors are pants. I can imagine a BMW service centre just fobbing me off with comments like those received by one of the US owners from BMW NA.

To further confirm the issue, I have been manually enabling the PDC every time I'm at a stoplight and sure enough, about half the time the car behind me magically appears in the red/yellow zone even though it's approaching at less than 1-2 mph.
And of course, my dealer claims I am backing up too fast and the sensors are fine, keep in mind never going more than 1mph and the sensors work fine sometimes when going 2-3 mph, but then dont work at all when going slow.. It's totally unpredictable..
So I backed up 5-6 times for them to show them the issue and every time, fast or slow, they responded differently. Sometimes working perfectly well. Other times lagging to the yellow/red zone instantly.
I really do not want to get BMW NA involved here but this is total bullshit. I really don't know what to do.
I paid $750 for these to avoid this shit. I want my $750 back or a resolution to my problem.
