BMW head lamp ballast failure.

BMW  head lamp ballast failure.

The BMW headlamp ballast is attached to the bottom of the light and has three bolts; two are accessible. Removal of  the third bolt would need to take the bumper cover off in order to remove the headlight.

Water gets into the ballast terminal and causes a short and in some cases corrosion on the terminal’s.

A dealership would typically charge two hours labor and a diagnostic charge. To remove and replace the ballast you have to take out the headlight, remove the bumper to get at one of the bolts. The cost of the ballast from the dealer is around $625. The after market on ebay would cost around $300. We at our repair facility charge two hours labor plus $300 for the ballast.
