DCC - how good is it?

[monkeyhanger]

MrSavage: Eco is not economical. Most people (GTI and GTD) get better mpg in sports mode. In eco, the throttle response is blunted so much, you just end up putting your foot down further.

The VW DCC/ACC uses electrical solenoids to change an oriface that the oil in the shock has to move through. The smaller the hole the stiffer the dampers ie sport mode.

What is the best way to test/feel the difference with the DCC?

For suspension travel it's got to be speed bumps.

But changing the damping does not change the travel, it means that you need a greater load to effect the same compression but the maximum travel remains unaffected...

Yes I do have DCC. I'll test it more next time I go over a speed bump. I'm sure it's just a placebo effect.

It's like Top Gear drove the GTI around the track in normal and sport and got the same lap times to the millisecond and Comfort which was actually 0.1 of a second quicker. So this in it self shows that the different settings do nothing at all to affect performance. So I'm assuming they do nothing in the feel of the ride either. But I don't have particularly bumpy roads around here.

So far, over 1100 miles. Would I spec it again? For £800? No.

That is very interesting. I changed from a Mk5  1.9 TDI to a Mk6 GTD. On the very bumpy B roads I drive to work I found the GTD too firm to drive at 60mph. Even with the suspension set to comfort and 16 inch winter tyres.

Back on topic - I sometimes switch to sport mode on good roads. If I drive to work I soon notice the difference and switch back to comfort. The car is very... hmm... jiggly on a bad road in sport.

Just try driving over cats eyes in the different settings. Though this is still much more comfortable in my old TDI which my wife now has.

The effect you are describing is secondary ride - high frequency, low amplitude

A speed hump, on the other hand, would give an indication of primary ride

There are speed bumps on the way to work. In the TDI, I was able to go over them comfortably at 30mph. My GTD will not comfortably go over them at 30mph. Even with comfort mode and 16 inch winter tyres.

So my experience is that my Mk6 GTD has poor primary and secondary ride compared to standard suspension and alloys.

Our Volvo has their DCC equivalent, but it is controlled with three separate buttons (Comfort/Sport/Advanced) in the console so you can shift quickly between modes on the fly with one touch and no menus - for upcoming speed bumps etc.  I think VW missed a trick here on the Golf.

Hi All,

Just had the car back into VW (250 miles covered) to check to see if any of the 'transport blocks' are still in place following reports on the forum. I really can't notice ANY different between sport/normal/comfort and have the DCC option spec'ed.

They got under the car, lifted up the bottom of the suspension gator on each side and couldn't see anything. The dealer mentioned that 'you'll only notice it round a track or at high speeds round corners', I'm not sure of that based on other peoples comments on this forum.

I argued the points about there being 3 sets in each but they were adamant they weren't in.

Couple of questions:-

1) They only lifted up the 'bottom' of the suspension gator, will there be a set higher up that they may not have seen?
2) Does anyone have any picture of these blocks in their cars before being taken out, or at least a diagram or something showing where they might be?

They may genuinely not be in there, but after spending the best part of £1000 on this option, I'm sure that I should notice some difference even at low speeds!
