You already have the correct code, I can confirm it is '2072'. Turn the radio on and go for a drive, the 'wait for one hour' message will go away eventually and be replaced by either'CODE' or '----'
There are regulations about the height and position of 'FOG' lights on a car.......roof mounted is a no go! However auxiliary 'driving' lights can be roof mounted BUT must only come on with the headlight main beams and go off when headlights are dipped......
I had the same problem with my K12, the cause was one of the clutch pressure plate support leaf springs had broken,
gearbox out and new clutch assembly was needed to fix....... :(
