Disc brakes and pads don't play a big role in stopping the Taycan in normal braking scenarios.Thanks, this might fix it. The appointment at dealer is in 3 weeks.
Just temporary, probably the pads are touching the discs and at high speed there's a friction noise cming from the front.
You do have to enable it.In my GTS under normal setting regen is disabled by default. Not sure if it's just gts but there is a button on steering wheel to disable or enable on demand
