front cigarette lighter not quite working

[andycaca]

hi guys
the front cigarette lighter in my S8 D2 works for the lighter unit, but not when i plug in the USB adapter for the satnav/car charger.

tbh, i think it needs a good clean of the contacts and a proper inspection. this would be easier with out of of the car.

does anyone know how to remove the whole lighter unit?
lastnight i had a look through elsawin and saw the advisory to bend out the negative prongs with a screwdriver, which is what i tried first off

thanks
