I had an ABS light after changing wheel bearings. VAG system showed left front
with a low reading compared to the other three wheels until it reached ten mph.

Turned out that the ABS sensor had been bumped so that it had twisted about 15
degrees out spec. I twisted it back straight and the problem was fixed.
