Hi guys,

Car had it's service today and also had a complementary wash and vac as well. Noticed that the rear parking sensors don't sound the same as before and seem to have a much higher pitch to them than normal. Noticed a young lad with a mobile pressure jet cleaning a car when I went along to collect her, could this have damaged a sensor in anyway?

Sensors still operate correctly by the way.

It has been commented on here on many occasions that jet washing directly on the sensors is not a good idea.
