On my way to my client today, through some 50mph average speed camera motorway roadworks, ACC on...... I get a BONG, followed by an orange cruise control light on the MFD and the message "ACC: no clear view" and "ACC deactivated".
What did I think the problem was?
A road sweeper had pulled out of the site entrance, in front of me, did several hundred metres, screwed my ACC up, then drove into the roadworks and disappeared.
About 2 minutes later, error light goes out, ACC is fine.
I keep saying its jamming and its definitely some sort of radar unit on those road sweepers...
There's no jamming going on...
I've seen the same in poor weather conditions e.g. snow/freezing conditions... with no roadsweepers. The roadsweeper probably coated the sensor in crud. Once the crud was washed off/ blown away, ACC was able to function again.
I did notice the other day when the local plod were doing a speed check in a village, ACC turned off (no warning)
