Quick question about dual-clutch autos

moonage

If you come to a stop at traffic lights can you put the handbrake on while leaving it in Drive?

Would the clutch be slipping in this scenario?

The car won't move until you press the accelerator.

It depends. On a wet clutch DSG I would have no issue leaving it in D.

Mine creeps forward but it's an older car .2008

If the car has auto hold its not a problem but on a Polo with a manual hand break I have to put it in N because the car wants to keep creeping forward while in D

If the car creeps the correct procedure is to keep foot on foot brake. Not the most efficient , but its what they do in USA. In a manual I would put car into neutral and pull hand brake. I doubt an auto is designed for you to constantly change it to neutral or park at every traffic light.

So, on a dry clutch DSG you'd essentially be keeping it at the biting point while the handbrake is on, which will cause wear on the clutch.

But on one with a wet clutch this wear doesn't happen or would be a lot less. Is this correct?

The wet clutch is kept cool by the transmission fluid and works differently to a dry clutch so I don’t think it’s an issue.

I think the only dry clutches on DSG are the older 7 speed ones. I might be wrong on this as I’m not too up on the different types.

No you can't on cars with a cable handbrake. The two Octavia's I had with the 7 speed dry clutch would fight with the handbrake, very annoying. Leaving your foot on the brake worked perfectly, I think it used the input from the brake light switch to understand what you were doing.
