it comes on if your going down the gears like a mad man. it is just telling you that it is controling wheel slip...

in the dry .....just turn it off.

it also comes on as it is just about to brake away on acceleration if it goes too far it goes out and the snow green light comes on and only lets it rev to about 1500rmp........or thats what it feels like..

 

iam gona be strandard sooner or later on a junction with a truck barring down on me....:blink:

Greystoke,

Is your car a VVTi?

The VVTi ECU is very fussy about speedo converters. If it isn't right the TC will kick in all the time for no apparent reason. It does it because the speed the ECU is seeing from the gearbox (to rear wheels of course) is different to the speed it's being told the front wheels are doing (via the ABS speed sensors) and so it thinks the car is wheel spinning.
