ABS/speedo problem?

hogweed · 24th August 2019, 18:33

Was driving along earlier today when I heard a faint tapping from under the front of the car somewhere – shortly after that, the ABS light came on. Car’s driving normally, but the light has come and gone all day (mostly come).

This all happened a long way from home. As I was driving back, suddenly the speedo needle dropped to 0. It stayed there a long time, then began a pattern of slowly climbing up to 30 or 40 (I was doing 70 or so), then dropping back to 0 again for a while. Them every so often, it would indicate my correct speed (amazing at how good I proved to be at guessing!)

Do these symptoms indicate a single fault, or worse? Any advice appreciated.

PS don’t know if it’s relevant, but about ½ an hour before it happened, the front o/s wheel got a bit of a thump in a pothole…
