Volkswagen DCC Adaptive Chassis Control - Design and Function


Volkswagen DCC Adaptive Chassis Control - Technical

Fantastic info Maverick
ALL the bits I was curious about, and THEN SOME

[sergiommms]

You guys mean DCC right?
ACC stands for adaptive cruise control.
Or so I think...

[REXman]

DCC=ACC. DCC is the new name.

As for DCC, I'll tell you straight up it's worth it.

As for it failing out of warranty it actually doesn't that much to replace through VW. Someone had posted prices of around $500 or thereabouts? per shock - like normal VW shocks would be much cheaper!

It makes the ride better no questions. If you can get it, get it.

Hey sergiommms, welcome to the forums.

Originally Volkswagen Launched "ACC" as Adaptive Chassis Control. Of course, around the same time they were also launcing ACC as "Adaptive Cruise Control". On top of this, they also already had ACC as "Automatic Climate Control".

So in Europe there has been a bit of an effort to rename Adaptive Chassis Control to DCC, Dynamic Chassis Control.

However, that has not occured in Australia. In addition, the ordering codes and VW internal systems all still refer to it as ACC.

So to clarify, this topic is talking Adaptive Chassis Control - not Adaptive Cruise Control which is not available on the MK6 Golf (at least in Australia) anyway.

I opted to go without ACC. I also stuck with the standard 18" wheels on the R. I have had big rims before and they are never cheap to maintain. I test drove a GTI without ACC and 18" wheels and was surprised with the ride. Minimal body roll etc... I also have questions of long term reliability of ACC... I have heard from a few ppl with cars older than 3 years that the system gets squeaky... I would like to keep the R for 3-4 years so eliminating high cost maintenance is important to me... Rather get after market sports suspension than be a saggy ass riding in weak comfort mode.

[Corey_R]

You do realise that this feature hasn't been offered for 3 years right?

[blanch0b]

what about retroviting the chassis control system to a GTI already bought? any mods available from APR or other similar company??

[Corey_R]

I haven't seen it offered after market yet. I'm pretty sure that the dealers don't even fit it as an accessory. If you check out the System Diagrams and descriptions on Maverick's site, you'll quickly understand that there are just so many sensors used by the system, that it's probably not that practical to install aftermarket.

Very good Mav.
The owners manual states that changing DCC from Normal to Sport/Comfort and switching off the motor will have that change hold for 2-3 hours (can't recall exact time - same as MFD from memory).
On my 2010 GTI - DCC Comfort mode was retained overnight.
Maybe a change from 2009 to 2010 models?

Still prefer the valving of the aftermarket Koni/KW kits with a broader spread between low speed compression valving and high speed compression valving ride/handling mix. It's harder on smooth roads and softer on rough roads or big hits. DCC wins in terms of convenience and active intervention, but the valving is more like an aftermarket H&R or Bilstein kit rather than a Koni/KW kit.
Been using Sport mode in the GTI more often since the last Golf R -v- Golf GTI drive review.
Looks like DCC dampers have settled in a bit after 14,000km of mainly country driving.

No ACC: Light or heavy?

I've just ordered an R DSG with 19" on Monday and it doesn't come with ACC. The dealer managed to convince me that if I don't track or race, there is no real need for ACC. Plus the roads in Melbourne are very smooth and nice.

Anyone tried an R without ACC and with 19"? Is it a very harsh ride or it's something that is hard to feel.

Also, I've test driven and R DSG with 19" and ACC. When in Sports mode, the steering wheel is stiff and heavy. It's lighter when in Normal or Comfort mode. Can anyone tell me how it is like on a car without ACC?

Many thanks!

[Corey_R]

The steering weight of a non-ACC car is the same as an ACC car in normal/comfort.

Does anyone know of a way to modify the settings of the adaptive chassis control?

I love the steering weighting and especially the throttle response of the sport setting, but don’t want to put up with the harsh ride on the bad roads in Sydney.

I can do nice heel toe changes in sport mode easily, but can’t do the same when in comfort or normal – the difference in the accelerator sensitivity is quite noticeable. Toe on the brake, roll my heel onto the accelerator to give it a jab and nothing happens, unless I keep my heel there for some time.

As opposed to sport mode – the revs go up nicely and immediately as soon as my heel touches the accelerator.

Is there a way to adjust the system so that the sport setting for the steering weighting and throttle response is also applied for the comfort & normal modes? Ie only the damper settings will change between the 3 modes?

There has been some conversation about the mode affecting the actual drive, I read somewhere that it affects the dampers but also activates the AWD and removes the bias. Wasnt aware that the acceleration was affected

This article from the VW UK website confirms the throttle response and mapping is also affected.

welll there you go.. the ACC option provides you with free sprintbooster

Then to answer your question.. no I dont think anyone has thought of how to address this but for roughly 300 dollars you can buy a Sprintbooster which will allow you to modify the acceleration but thats about it
