Guys

 

Rear parking sensor goes crazy all the time and when i select reverse it rings uninterruptedly so that i want to disable it, is there an easy way that i can do it by myself or need to go for a mechanic?

If it's on a seperate fuse, which i would've thought it is, try pulling the fuse out. It sounds like one of the sensors has failed. You could try popping each sensor out and unplugging it, try putting the car in reverse see if it stops playing up.

If you got Maxidot then you might disable sensor's sound there.
