Real vag com cable and software can get pretty expensive. You could buy a cable off eBay and download rosstech software there is a DIY sumwere on here try a search

The ESP and Brake light (or ABS light) together, always on might be faulty brake light switch. Check to see if your brake lights work when you depress the pedal. If the brake lights do work, then might be a ABS wheel sensor.
