I own a 2006 1.4 Style. About 3 years ago the ABS warning light started illuminating randomly. I had it checked out and was told it was a fault with the sensors on the front offside wheel bearing, but advised to live with it as it wasn't part of the MOT test, and indeed it has passed 2 tests since. Is it now a MOT failure and what is the replacement of a wheel bearing likely to cost. Thanks for any advice.
