I've had my ABS light coming on in my 6 for ages now and despite passing last year's MoT with it (??!), it always niggled me that it must be on for a reason ie. a fault in the system somewhere. I read so many other posts on here from folks with the same problem but no one seemed to ever follow the faq.
So today, armed with my trusty multimeter, I set about testing each sensor as described in the FAQ. After about 5 mins I sourced the problem to the front passengers side and luckily I had a spare so was able to swap it out. Put it all back together and guess what....no ABS warning light any more!!
Moral of my story, read the faq's that others have taken the time to write, and most of the time it'll solve your problems.
