Do I have a traction control or ESP button????

[Harlequin]

mine is a mk1 - so assume the same ?

I would assume so, if you have a button to deactivate it, there should be a light on or near the switch that comes on when you press it. When it re-enables, the light should go out indicating the system is active again. In either case it should revert to the active default once the ignition is switched off.

Here's a list of the functions and when / how they operate in case you're interested (click table to zoom):
