Couple of comments on above topic: 1) According to the Highway Code, you do not need to apply the handbrake at every junction or traffic light; however, it is generally considered good practice to use it if you are stopped for a significant amount of time, especially on a hill, to prevent your car from rolling unintentionally. However, it is a good practice to put a handbrake on to prevent hitting car in front in case someone smashes you from the back. Considering that (especially for those who used to practice applying handbrake on the traffic lights), it is not practical to keep the car on D and pushing the foot break at the same time. Combination of D and handbrake will surely burn the clutch as clutch will be engaged as long as foot break is not applied. 2) IMO combination of N + handbrake while you expect to stay for a bit longer is the best for those who practice applying the handbrake

 

The logic controlling the DSG clutches fully disengages them when the brakes are applied, when you take your foot off the brake, the clutches engage a specific amount of torque to replicate automatic creep. So no, you don't wear out the clutch and don't need to put it in N.

The video proves this, showing zero engagement when on the brakes contrary to the assertion in that post.

 

I asked this question at the garage when I bought it and was told to keep it in D.
