So I serviced the old bus and a quick jet wash after and now the front parking sensors packed up to join the rears. Do these things just not like water. Haven't been able to get behind them to get a proper look but that's my rant to close a stressful week.

They don't like high pressure water, but normal washing and hosing down us usually OK.  Mine occasionally did it after washing but always recovered by the next day.

Try a spray of wd40 to expel the water

Seem to be working  again tonight. Just got to sort the rear. Identified as rear left centre by garage. Please tell me I can access this without dropping the bumper?

5 Minutes of a job if you haven't got a tow are fitted, remove the cover plate Where the tow bar would come out.
Put your hand in to feel the rear of the sensor surround. There is a tab underneath, pull the tab away from the sensor, this is the retainer for the sensor housing. Then ease out the sensor, unplug the wiring plug. Hey Presto
Once removed  you have to strip the outer sleeve off the removed bit ( easier to do when you see it for your self.
Re fit and all sorted.
