I have the knob in the boot on the right, the light goes from red to green etc, however when turning and holding I can’t release the tow bar, that means I can’t deploy is there anywhere I can spray or check the solenoid

Hi all help is needed here please i I bought my c6 Allroad about 12 months ago, the seller said the backup camera needed calibration I’ve looked around etc as I was told it should work but a blank screen through mmi 2g high is more likely a hardware fault. i have changed the switch box on the right hand side, I have fitted a 3rd party camera. Then I found the Audi only works on a 5v system so with 3rd party camera I boosted the v to 12v and bingo I have a picture. i have now bought an original camera and back to a blank screen so boosted to 12v and it works. i was then told it’s the mmi screen so I have updated to an android radio and again blank 12v and it works how do I increase the power to the camera or is there something wrong else where? many thanks
