UK-POLOS.NET - THE VW Polo Forum

Recently the parking sensors on my polo have decided to only work on occasion, the same goes for when I put it in reverse, the beep will only happen now and then.

I'm guessing it's something to do with a wiring connection.

Does anyone know where I'd access the wiring for the parking sensors or any other possible causes for this?

Cheers

First thing to work out is if this system is a VW Group system fitted at factory, or a VW workshop retro fitted Cobra system, or a 3rd party retro fitted system.

Like said you will need to determine what’s fitted, but as a starting point
In the boot area take the trims off the sides and possibly the rear and trace the wiring from the sensors to a control unit ? This may give you a clue what your dealing with.

Good luck
