Ouch, wide spread for the water jet required, i'm always a bit wary using the pressure washer on car, as have cut the surface off patio slabs with it!

It was maybe a high pitch scream from someone you just knocked over

I think these car wash places are over enthusiastic with their use of a jet wash especially if the car is filthy and they also tend to use the more powerful versions.

I haven't experienced it with my Evoque but I did with an RRS every winter when the car got very dirty after snow and the roads had been salted. The problem with pressure washers is that if the jet is directed straight at a sensor it can damage the covering and fill the sensor head with water. To find out which sensor is in fault get somebody to sit in the car with the engine running and the sensors switched on and walk close to the heads, you may hear one clicking, that is the faulty one!
If you put your ear to a parking sensor while reverse is engaged it SHOULD make a clicking noise, we have problems with park sensors all the time, if it's not the sensors it's the wiring
