demonjrm: I've been tackling the same issue on my mk7 Golf, and what you describe is similar in my car.
I'm not sure if I have transgressed forum etiquette here (given golfi_vend's post) and I hope that the Benevolent Dictator will be kind in his advice to the contrary, but here's how the TCS/ESP button works on my car.
