I went for a test drive in a second hand 406 estate yesterday. Nice car, very impressed. Two things worried me: 1. on braking there was a liquid sloshing noise. It sounded like it was coming from the nearside but the seller dismissed this as "noise from the plastic fuel tank" 2. on braking there was a slight bumping. After a while this stopped but the orange ABS light came on on the dashboard. The seller admitted he was puzzled by this and said he had tried fitting a new ABS sensor on the front nearside. Do either of these things sound like a serious problem? Thanks for any advice Andy
