I have a 2006 grande dynamic punto which came with front and rear parking sensors (doesn't look like factory fitted).
I had my car washed full valet the other day, and have noticed today my front sensors are not working, the back sensors are working.

Anyone have any idea how to sort this? I have no idea whatsoever regarding these sensors.

Forget that! Already sorted!
Previously wondered what a button did rusher wasn't in the manual, now know it's the front parking sensor button!
