Parking Sensiors Constant Noise

[wazza]

Have a 1 1/2 yr old MkIII last week the parking sensors make a constant noise as soon as they are sqitched on, anyone any ideas of what it could be, appears to be coming from the front sensors but ths also seems to override the rear ones as well, Any ides of why they are sounding like this?

 

Thanks in Advance

A continuous tone means there is a fault in the system. It will log an error code if you have a suitable reader and this will have to be cleared to reset the module. Check for obvious obstructions on the sensors themselves, otherwise it could be a wiring fault.
