PDK out of gear at lights?

Not sure I can accept this. Using the brakes to hold a car stationary can't be anywhere near as hard on the brakes as using them to stop a car.
Sorry,I maybe should have added "when brakes are hot it's not good to sit with your foot on the brake while stationary". I'm not a mechanic by any means but i think it's to do with heat build up on the disc and can lead to warping apparently.

Of course you can move the selector to N when stationary at the lights if you want to - just as you can with any automatic. It's just not necessary. Porsche says leave it in D.
.
Yes, agreed it is not necessary, but neither is good driving..
And yes P suggest to leave in D in their owners manual but I interpret that advice as aimed at the lowest common denominator of know-nothing drivers for their convenience.
My question is a technical one. Do I cause more wear and tear by moving into N and back (often with a bit of throttle on)?

Just a thought:
At night, just consider the guy behind you at the traffic lights having to sit looking at the glare from your brake lights.
Even in a manual I keep my foot on the brake - at least until the car behind has come to a full, complete stop. It makes things nice and obvious to the car behind. I also sometimes pump the pedal to make my brake lights flash if the car behind is approaching fast (or from a long way away at speed like the motorway). I'd rather annoy the odd person than be smacked from behind at speed.At night, just consider the guy behind you at the traffic lights having to sit looking at the glare from your brake lights.
I have a 2009 gen2 Boxster with 7500 miles, regarding leaving PDK in drive, I never hold car with my foot on the brake, always hold car on handbrake, it pi**es me off being blinded by LED stop lights from the cars in front, I have more regard for my fellow drivers. Anyway, if I have not applied handbrake HARD enough the car will move forward, this indicates the clutch is engaged and slipping producing wear and heat.
I recently got a red warning ( gearbox fluid overheat) while sitting in traffic, I had the handbrake on with box in D, this has never happened before but it is the first time I have sat in traffic for such a long period. I turned off engine, restated car, warning did not return, have driven car since with NO issues, I wondered whether the car being stopped in D for that pre-longed period with clutch biting had caused the sensed heat build-up or was it just a software glitch. I now always put box in N with hand-brake on and foot-brake off.

It is. Pulling both paddles will change the car into manual. If you don't continue to control via paddle, it'll resume fully automatic mode.
No, pulling the relevant paddle will temporarily override automatic mode. Pulling both paddles together (and holding them) will disengage the clutch.sidicks said:
