Thought I'd put this one out there:
When stationary at a longer set of lights (waiting for right red arrow to change on a main arterial road, for example), is it better to shift the DSG into Neutral? Or keep it in Drive? Or like a conventional torque converter, it really doesn't matter?
Obviously when stopped only briefly (a quick changing set of lights, for instance), I'd just leave the gearbox in Drive.
I think I've come across a mention somewhere that with DSG gearboxes it's better to shift it into neutral. But I'm not sure where I came across that and a quick search on VWW did not shed any light. I'm aware that one must never coast the DSG in neutral, as the gearbox is not fed oil unless it is in gear.
What do people think?
When you are stationary at the lights AND your foot is on the foot brake, the transmission is automatically placed in neutral.
Note, the foot brake must be applied. If you have just the hand brake applied, then the clutch will try to engage and cause overheating and wear.
When you lift your foot off the foot brake, the normal sequence to engage the clutch starts.
So the only time you must put the transmission in neutral is if you only have the hand brake applied.
I do this when I drive my misses car.. mines manual & so being a manual driver, its the metal programming/ force of habit to grab the shifter when im driving her car.
I have noticed that when stationary at the lights, the consumption according to the MFD is hovering between 1.1l/h and 1.2l/h
where as if you flick it to neutral it hovers between 0.9l/h and 1.0l/h.
It's not something that I want to do, flicking constantly to neutral, but there does seem to be some load on the engine while in D.
If the clutch fully disengaged, there wouldn't be any load on, should it?
