Hello,
recently I have noticed my ACC is not reacting, not showing any fault, for example 'Acc and braking guard not available'
its just not reacting at all
any help l? What it could be?

try cleaning the sensors in front maybe?

Collak

The car is all clean.
I changed the front grill, I had to install front sensors somewhere else, so It showed me an error for sensors, but just clipped it once more time and it started working normally, and now its not reacting at all, the lever moves all good but its not showing anything...

I think the ACC sensors are the little globes where you would typically find the fog lights. Maybe during the grill installation something got unhooked.

The sensors in the grill I think are for the nigh vision or something else.

But if anything got 'unhooked' it would warn me with message 'Acc and braking guard not available'
But its not reacting at all!

Sounds like the radar sensors may have been knocked out of alignment and need to be re-calibrated. You'll have to take it to a dealer. It requires shop equipment and costs a few hundred $. It's a labor intensive process from what I heard.

Just checked it for faults, its telling me Distance regulator :'Incorrectly positioned'
I just did lower it by vcds(Air suspension), could it have affected it?

Yes, I believe so. I know you can only lower it so far before it affects ACC. If you have the sport suspension that number is even less.

I would try putting the suspension back to where it was before you lowered it and see if the ACC problem is corrected.

Good Luck!

I have lowered it to 406 with 402.
Default are 390 with 386

Just made it 402 with 398 still not reacting.
I cant even remove the fault from Acc module which keeps saying me 'Distance regulation: Incorrectly positioned'
I can remove it but it shows up immediately...
Looks like its not letting me lower my car at all...
