ok, so this is my understanding so far... At the moment i think that the switch is playing games, however, the slip and tcs light come on when i either launch the car hard or take a coner too fast. (this is after i've pushed the switch)
so, possibly the TCS is turned off, but i don't notice any difference, the car still oversteers and wants to correct itself
the TCS and Slip light comes on when i start the car up
Any other coments are welcomed, Thanks guys
