Parking sensors not working on brand new e220

[018125]

Hi All,

Picked up a new e220 SE estate yesterday and the parking sensors were working fine.

I turned them off and then turned them back on again, but now they do not work. I have reset factory settings and read the manual but can't find anything related to this problem.

There is no sound at all. The red light on the parking sensors button is off, and there are no warning lights and failure codes.

Could be a fuse? It normally beeps an alarm at you if it is powered and faulty, mine did that when one of the from sensors failed. If the whole thing is off it is either switched off or a fuse I would suggest.
