ACC error

[C2K]

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...

Interesting post this. Mine has started doing this quite a lot recently having had 2 years of trouble free cruise control. I drove to London and back last night on the M1 and got it both ways - both times in 50mph average speed roadworks (where you most need the damned cruise control).

I get the ACC No sensor view message and ACC Deactivated. Needs to go back in the dealers, but my dealers is one of those where as long as the ACC works on the 1 mile dual carriageway there must be no fault, and proceed to delete all the fault codes.

After an indeterminate number of minuts (5 or so) it always comes back.

I've been getting the same errors on the ACC as others. Been happening for the last 6 months or so. Bloody pain!

What's odd is that the fault disappears when you switch the ignition on and off again. Not very convenient when using the system on the motorway in a 50 mph average speed camera zone.

The fault is so intermittent I'm not going to take to the dealers unless the fail frequency increases. At present I can go months with out the ACC error occurring.

Darn gremlins

I never had this fault - maybe because roadwords in parts of motorway I use don't have metal barriers left an right......
There can be reflections in narrow lanes that throw the system off. Especially in heavier traffic (where you'd want to use ACC especially if you have a DSG box).

I would go back to the dealer you bought it from just incase its an on going problem and you have to reject the car...then they have all the history in house.

I had an ACC fault pop up about a year a go, which coincided with me going over a HBB a bit too quickly & also a large leaf stuck over the sensor.

I therefore can't be 100% which occurence triggered the warning, but my local VW dealer found no faults, & it has never reappeared since.

ps.  There is a 2013 GTI down my road with red calipers, but no ACC sensor in the front grill.

Does anybody know if this would be a non-PP GTI with painted calipers, or was the ACC not standard on earlier cars, because I didn't spec. this feature with my car, it just came with it?

Possibly an Irish model as 2013/2014 models were woefully underspecced.

Spec improved from late 2014

Probably a 'Launch model' which had pretty much all the same features as the later ones but no adaptive cruise.

I had a very similar thing for the first time today going through a 50mph camera zone on the motorway, I use the speed limiter. The car in front of me was going really slow and eventually pulled in, as I got close I got the bong message about ACC no field of view, 30 seconds later it was working again, I even tested the ACC and it was fine. It was drizzling at the time though on a window bridge, maybe a chain of events caused it??? I'm not sure but will be keeping and eye on it!
