Hello,

 

New iV owner here. I've noticed that when using ACC, my brake pedal physically moves as the brakes actuate. It's most noticeable in towns with stop start traffic. It appears to make almost the full range of motion (like there's a ghost pressing it)

 

I've come from a B8 Passat and had a MK7 golf before, neither of those moved the pedal when ACC was in use, so I don't know if this is a new 'feature' or whether I need to get it looked at?

 

FWIW the brakes at other times work as expected with the exception that every now and again they turn noticeably spongy

Yes, it's meant to do that - I had a Golf 7.5 before and it was a bit unnerving when it happened in the Superb!

Never noticed it happens on ours, but then again, I’ve not kept my foot on the brake nor have I looked down at it when ACC is braking. 

Yup, mine does it when brakes are required over regen retardation. 
 

With ‘road layout preview’ ticked, you get a warning on the VC of corners and roundabouts ahead. If you approach a roundabout with ACC said, you definitely feel the brake pedal moving!

 

Note - I’ve only tried this on quiet roads with my foot hovering over the brake pedal, ready for manual braking…

 

I do think the ACC is a very clever bit of kit - not just for the above but also the way it susses out rate of closure on traffic in front and reacts as soon as you indicate and move out to overtake (dual carriageway cruising). 

Thanks all. I only noticed it today when I went to override ACC and the brake pedal wasn't where I expected to find it!

 

@aerofurb agree this iteration of ACC is very clever, it seems able to spot pedestrians too; my Passat wasn't that good.
