My passenger head light suddenly stopped working. We thought that it may be the light bulb. We replaced the bulb with a working one and it still does not work. We were advised by a mechanic that he "thinks" that the ballast needs to be replaced. Does this ballast have replaceable components or does the part need to be replaced completely. We were told that the part is $200 to $300. I did see online that it looks like there may be ceramic fuses that go inside this ballast. Has anyone ever had this issue? The information that we received was not from the BMW repair shop. BMW will charge $120/hr to diagnosis the issue and then an additional parts fee.
RepairPal Certified shops can diagnose and repair your 2005 BMW 330xi. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
The standard proceedure is too replace the ballast. You can swap your ballast side to side to check and make sure that is the issue. We will not charge you a diag fee if you want it replaced by a train professional.
Thank you so much for the response. Do you know what the approx fee would be to replace the ballast? Thank you!
