I took my X5 in for a bad actuator on a door lock, a light on my dash came on: the right rear tail light.

The dealer is telling me that I need to replace the whole tail light assembly because of a burn spot on the circuit board.

What I don't understand is: the lights all work (tail lights, blinkers, brake etc...) and it is not covered by the CPO so they want close to $400.

what lights are affected? (the ones on the hatch?)

what are my options and beside the annoyance of a light on my dash board

Advises?
