power cut after traction light comes on
 

Hi, I recently noticed that my cla cuts power when ever i do wheel spin, happens every time, more on wet roads. when ever i shut car off it drives ok until next wheel spin. when i torn of ESP all ok no issue at all. No faults with obd reader.
Any idea what could it be

well that is one fo the things traction control does.
you spin tires and it reduces power so wheel stops spinning.

Yeah but that power cut is on until i shut down car,
could be like 15mph in 2 gear and thats all
it wasnt like that when i bought the car
