Issue with clutch reversing?
Hi everyone, I recently replaced my C63 507 edition with a 2016 GTS and there seems to be an issue when the car is in reverse. When reverse is engaged you have to really rev the car to a high rpm to get it to start moving, almost like a slipping clutch or something. It seems to do it more when the car is started from a cold start and moving out of my garage. I think if I had to reverse it up a hill it would struggle to even make it up! Does anyone know what this could be? Thanks in advance.

having the two parking break realeases, excuse my ignorance but what is the difference between the ‘p’ button on the gear lever and the pull release next to the steering wheel? Obviously they are different, but why the two?

P on the console is putting the transmission in park, which automatically engages the electronic parking brake. The lever on the dash separately disengages the parking brake ONLY. If you put the car in park, and then put it back in drive/reverse to start moving again (including shutting car off/on again) and DON'T manually release the parking brake with the lever on the dash, the car will automatically release it as mentioned above, but it takes a bit of torque/movement for the car to release it. I am sure that is a safety thing to prevent it from simply taking off with little resistance.

Check the condition of your battery - they can misbehave between P/D & P/R, when the lacking charge.
Easy potential fix, that I know worked for me and another owner.

Are you saying that if you just push the 'P' button, and take your foot off the brake, it won't roll? Because that hasn't been my experience.

In older years, automatic transmissions would have a pin as park that locked the tranny in place.
I do not know if they implemented a similar system on the DCT.
but this will tell you more than you ever wanted to know.

in short the paring brake in installed inside the rotor of the brake, basically a little mini drum and shoe set up.
whereas the park mechanism is within the gearbox and locks the out shaft of the tranny so the wheels won't turn.

I also hear the parking brake being engaged (and feel the brake pedal move) when I simply press the 'P' button. The odd thing is that the parking brake engages when I open my door, even if I never touched the 'P' button. Maybe it's a MY thing (mine is a 2017), or maybe your'P' button isn't functioning correctly?

Sorry to bring this thread back from the dead, but my new-to-me 2016 GTS is exhibiting similar behavior.
I had a situation the other day where I was stopped in line for a traffic light, and decided to turn around, requiring a three-point turn. The parking brake definitely wasn't engaged, as I had just come to a stop and was holding the brake pedal. When I put the car into reverse, it took probably 50% or more throttle just to get the car moving at a crawl. Didn't seem like the clutch was slipping or anything- the engine just didn't seem to be responding to my throttle input.
Is this something to be concerned about? I only have ~6 months of factory warranty remaining, so I may take it in just to be safe, though I'm not sure they'll be able to replicate it.

When my GT S is parked in my garage for an extended period in cold winter weather, I need to rev the engine a fair bit when backing up to overcome the parking brake sticking, then it starts to move abruptly once the parking brake gets unstuck. However, this shouldn’t happen when you’re just driving the car on the road. Even when parking the car (when auto parking brake engages), it shouldn’t stick unless the car is parked for several days/weeks in a damp or cold environment.
