On my A6 Avant the boot handle works intermittently and the reverse camera (looks to be all one part) works for two secs and then goes black.

Is it simply a new handle I need to order? Anyone a similar experience? Common fault maybe? 

Thanks in advance 

Sorry meant to add I done a fault scan on Carista (not the best tool I know) but I meant my mate my Vagcom cable at the min. No fault codes relating to the rear camera or handle showed up.
