Hi Guys, Probably been discussed a thousand times but I am new to the site and BMW. I was for my sins for many years an avid Alfa fan (sorry) Yesterday all my ABS lights came on and my speedometer also did not register. Then it went away again? I am expecting it to come back though as this is of course a sign that something is wrong. Bottom Line what would be the worst case scenario? I don't imagine in this case that it is simply a wheel sensor. Cheers Sam
