First thing I would check is to see if the reverse lights are working o.k as usually tied in with parking sensor circuit .

Put ignition on , car in reverse and go to the rear of car and put your ear next to sensors and see if any are not making a noise .

Thanks for that. Tried it and no noise, got my neighbour to double check and he confirmed it - anything else I can do?

Check fuse f14 in case it's tied in to fault , if not you need to get it scanned
