I have a 2003 325it wagon with factory xenon headlights. The passernger side has developed an issue where it does not want to start when initially turned on. I replaced the ballast and igniter and it has new bulbs (although cheap ones from Amazon). If I repeatedly cycle the headlight switch it will eventually catch and will work fine for the rest of the drive. But the next day it will be reluctant to start up again. I would appreciate any thoughts. Thanks!
