Hi I have a xf 09 diesel lux 2.7. When I started the car today I had a warning come up saying parking aid inhibited contact your dealer. None of the sensors work front or back. Before I go to the dealers anyone have any advice that I could check, just wondering if this heavy rain could of done something. Any advice would be welcome.

 

They could be simply dirty but most likely something is wrong with the unit or wiring. I had similar isses but discovered that a cable was not connected. I took out my left-front headlight and was able to reconnect the cable. Now everything is working great.
