As I said further up - the drag experienced on the wet plate DSG's is not due to the clutches being partially engaged - its due to hydraulic drag between the closely spaced clutch plates.

The dry plate DSG's obviously don't experience this effect and so you don't feel any 'creep'.

On both systems the application of the brake pedal causes the clutches to fully disengage. This is necessary not only to reduce clutch wear, but also reduce emissions.

The reason VAG (actually BorgWarner - who designed and developed these transmission) recommend you leave the transmission in D is that there is possibility that many drivers could increase RPM iwhen setting off, prior to the mechatronic unit fully moving the transmission into 'D' - this can cause a shock load to the transmission.

You only need to move to N when stuck in traffic for a lengthy period on a very hot day. Moving to N will reduce heating of the fluid and keep the transmission cooler.

I did wonder why the car would creep when in D. This explains it.

I wonder when the 7 speed wet clutch DSG VW are now using will reach the lower levels of the VW group?

My father taught me

(i) Never keep ones foot on a clutch, nor slip a clutch, in or out or foot on the floor,

(ii) Never rest ones hand on a gearlever, it will wear the selectors ( not applic to DSG I presume)

clearly your dad wasn't much of a pedant.

(i) the clutch is always slipped when engaging or disengaging. it's the degree to which it is done that is important

(i) merely resting one's hand on the gear lever will not wear anything, except maybe the palm of your stringback driving glove. pressuring it towards any of the gear positions might wear something like a selector fork. eventually.

My driving instructor (many moons ago) taught me to apply the handbrake and put the car in neutral when waiting at a junction etc, also he used to smack my hand with a ruler if i left it on the gear lever too long (ruddy well stung too) .

My main gripe about not using handbrakes when vehicle is stationary is the brake lights being (in my impression) very bright on cars these days and in some cases particularly with high level 3rd brake lights almost blinding.

erm

Yes I am aware of how a clutch works regarding "slippage" being necessary. Doh!

EDITED:However clutch slip is only necessary when pulling away from rest, in 1st gear, for say, oh about a second or less, with minimal revs, therefore causing no undue wear or damage.

All other gear changes once moving do not necessitate clutch slippage, merely match the revs against the vehicle speed.

No clutch slip involved, if a competent driver.

If really good ( & I cant) perfect gear changes without graunching are possible without dipping the clutch at all.

Ps

And actually when in the ould Galaxy today its 228,000 miles ( & counting) , & should make 250,000 without any bother.

And her be a wee bit "tweeked" and has towed a fair bit and most of my milage is stop start town work, not bad I think.

Brasso or Duraglit for my Halo polishing then?

When I was taught to drive I was told it was bad manners to sit with your foot on the brake and thus your brake lights on because you blinded the person behind you. Nowadays no body seems to be bothered about manners, driving or otherwise and many people are just far too lazy to use the handbrake. If I come up behind a car sitting there with it's brake lights on, I tend to stay back a bit and put my Xenon headlights on main beam. It usually make the brake lights go off!!!

......Therfore dazzling the oncoming traffic!! that's a really clever Idea you have there! :clap:....have you ever heard the saying 'two wrongs don't make a right'
