xenon modules due tend to get water ingress very easy,make sure your order the right part since the smc ecu is very similar. Removing headlight is needed to access ecu,some BMW you can snake out the xenon w/o removing headlight but i dont remember for E63 I usually need to remove inner liner from what i see i make the choise to r/i headlight. Starting from E65 r/i bumper is ness. To r/i headlights
