I have intermittent ABS warning on my 2.0 hdi diesel xsara Picasso. one garage Say's it needs two new sensors however another garage tested it and could not pinpoint the problem as anyone experienced the same fault. arnold
Each wheel has its own sensor - front and back - and they need to be clean - as does the toothed reluctor wheel that operates them. A snapped wire will also have the same effect. Thats about all you can do, apart from visiting a specialist who can test them for you.
