The passenger side daylight running light stopped functioning. I called BMW dealership while it was still under warranty and was told that if it was simply a light needing replacement it would be $500. At the next oil change I had a diagnostic test done and was told that the modules for both daylight running lights had overheated and melted and that a headlight also would need replacement. The cost of this was quoted at $4,200. This is a huge safety concern as this could easily cause an electrical fire. BMW was contacted and refused to cover the cost as it was 2000 miles out of warranty when the oil was changed.
