DSG coasting

[Top Cat]

This topic came up a while back and i remembered it was something that should not be done. but can anyone tell the peeps on here what the actual damage would be done to the gearbox if this was done regulary.

you shouldnt do it in any auto car!!

It's all about the lubrication if I remember correct.

But give it five minutes and T_T will be along to make your brain hurt with the full technical explaination.

I have no clue what you are talking about Top cat (Whats new though  :embarassed: )

Will wait for TT to fry our brains with info overload.

Sorry if this is a dumb question but by coasting do you mean changing to N (neutral) and letting the car run under its own momentum?  For example when approaching stationary traffic I sometimes change to N and let the car free wheel for a bit before applying the brakes.

yea!!^^^ shouldnt be doing that

Ok a couple of weeks back i mentioned that you should not put it neutral and cruise to a stop to save fuel.
Although most people know this is a no no a few people new to DSG did not, But when asked why you should not do this i was unable to tell them what the damage incurred would be.  :embarassed: But the font of all knowledge is on-line so as you and SteveG said prepare for technical overload.

i bet TT's only on his 3000th word by now, so his post will be finished soon

Do NOT shift the DSG into N when the car is in motion.  The DSG oil pump is on the far end of the box, and is driven by one of the input shafts.  Therefore N = no (or very low) DSG oil pressure and oil flow.

Its the same reason why the DSG should never be towed.  Even on conventional manual gearboxes, "wheels-on-the-ground" towing is strongly discouraged, and should only really be flat-bedded.

Furthermore, coasting in neutral actually uses MORE fuel - I'll let you chew over that whilst I nip out for a while, and have another play in the Touareg I'm borrowing at the mo!
