My brake switch went a couple of weeks ago guys,no brake lights were working at all.It was also causing my Traction warning light and my Glow Plug light to come on. Ive now got the switch replaced but my brake lights dont come on unless i really press down on the brake peddle.I took it back to the Audi specialist that done the work and he said he has adjusted it. It is now no different and when i have been pressing the brake to see when the lights do come on,then the Traction warning light comes on. Anyone any ideas as to what this is?Is it a faulty switch or has the guy not adjusted it right?Also he said when he plugged in the diagnostics it wouldnt talk to the ABS system.Is this related you think??
