DCC and ACC?

The DCC in MK7 is a version 2 as it now adapts to conditions 'actively'  - This is quite an important difference as no matter the setting the suspension is reacting to the road opposed to just being physically adjust to the mode set - Video explains

Chris Harris seemed impressed and you could physically see the differences in his video as he changed settings.

I have an S Line suspension and roads here are quite poor combining to make quite uncomfortable moments! so comfort of ride was #1 on my list to fix!!

With generally good GTI/GTD suspension enhanced further by the DCC it seems my experience is going to change quite dramatically

ACC can also stand for adaptive cruise control

MK1 ACC also adjusted actively, but only in "normal" mode - the other 2 modes were the 2 extremes of the system variance between hard and soft. I would assume same can be said for MK2. The biggest difference between MK1 and MK2 is independent control of each corner as opposed to the whole axle, which should improve things a little. Took my dad's car on a moderately sh!tty road on the way to pick up the take-away last night and the ride was impressive without the ACC, smoother than my Scirocco in "sport" mode.

But is there still some doubt about if your Dad's car has DCC or not?  (I prefer to call it DCC to avoid confusion with the cruise control).  If the options are on the menu then how sure are we that this only affects things like steering and throttle response?  I just can't imagine they put that menu on all cars if they have DCC speced or not.  For one thing when the car is sold how would anyone know if the option is fitted or not?  If you spec it in factory build you've no way to confirm it is fitted (sales man can point to the screen and call that proof).  If you buy off the forecourt or second hand, again they can claim it is fitted and how can you tell?

Doesn't seem likely to me.  I'm leaning towards thinking your Dad's car has got a free option here...

Are people not thinking of the driver profile which is standard??

I think that is what MH thinks it is on his Dad's car.  But if this is the case why does it include options for the ACC?

I see some possibilities:
1. No ACC/DCC as it wasn't spec'd.  Menu still exists but does nothing.  This seems least likely to me.
2. ACC/DCC mistakenly fitted to this car.
3. It refers to something else... cruise control maybe?  Does cruise control even have "sport" or "eco" mode?  Why would it?

Easiest way to tell is to check the shocks under the car. If it has electrical wires attached then it has DCC if not then it doesnt. Otherwise check the spec codes in the boot.

If ACC/DCC is fitted, there will be a switch by the gear stick to switch between Sport, Normal and Comfort.  If it's not there, then the selections are simply the driver profile options, with no dynamic damping going on.

What are spec codes in the boot?  This sounds like useful information!

Is it there anyway to access the driver profile regardless of if ACC/DCC is fitted?  Gotta be sure about this one!
