Parking sensors

[bh78]

Hi

Just picked up my new 2012 D4 HSE. Question for you all. My parking sensors seem to turn off on random occasions after start up. Pushing the button rectifies this straight away. Read the manual to no avail.

Any ideas?

Cheers BH

Can you clarify? Do you mean that when you select reverse they sometimes do not come on?
