W202 traction control prob

Hi I have a long drive and a private road

I took the w202 c240 out running on 17 inch staggered Amg alloys monoblocks

Question

At 80 mph the traction control light keeps coming on then loose power unless you lift off
Also if I hit the traction control button too turn off the car keep s accelerating

Tyres are

Rear 245/40/17

Genuine alloys
