Re: 05' 745li adaptive headlamps
Usually when we see these symptoms in our dealership, its usually an indication of a failure within the adaptive headlight assy. Based on experience alone, I'm certain that there is moisture within the SMC module in the headlamp assy. (SMC=Stepper Motor Control) The only real way to tell is remove the entire headlamp assy. One thing to remember is that the drivers side is the "controller"
