I have a 1997 328i and it was in a local shop to have the valve cover gasket, Oil filter holder gasked and belts changed. A couple day after leaving the shop, I go to drive the car at night and find that the low beams do not work at all. There is a check that says the low beam is out. I have checked the fuses and they are good. I am not sure what else could cause both of them to be out at the same time. The connections to the bulbs looks good.
