Recently the ACC in my 2004 740d stopped working from one day to the next.
When I try to engage it I just get the "---km/h" for a few seconds on my speedometer as if my speed was below 30km/h where it shouldn't engage.
Could this be the ACC-sensor itself or some other speed input to the ACC?
I just got INPA installed on my laptop but I'm having a bit of difficulty finding my way around there. I managed to navigate to the ACC in the menues but couldn't figure out how to simply get a reading from the sensor to see if it's working or not.
