Leon Cupra 280: Hitting while accelerating

Moin together! Have a Cupra 280 since the beginning of the year. After the drive-in time is now over I wanted to give a little bit more “gas” now. The following problem has occurred: Every time I accelerate from the stand more strongly, so that the wheels would spin off, such a blow or also banging occurs, sounds really bad. Especially in wet weather this is even worse – probably because the wheels have less adhesion… Except for this problem, the car runs inw I’m going to go to the Seat dealer, just wanted to know if someone had something like that before. Maybe that’s normal too – but somehow I can’t imagine… By the way, I usually drive in comfort mode, if all this could have to do with this front axle lock… Thanks for the help!
