Is it harmfully to the engine to run with the N75 electrically disconnected? My thoughts are to fit a switch into the power feed on the N75 harness to cut the power and act as a valet mode. Would this work? Heard too many stories about valet drivers abusing cars here. One of our local club members had a mk6 gti with k04 and the valet driver managed to write the car off as he pulled off. He smashed into the back of another car.
