Okay so we've picked up a stone crack on the front driving light. It's now filled partly way up with water and condensation. Although the idea of putting a goldfish inside and turning it into mobile fish tank seems mildly appealing, probably the best option is to replace it. Anyone have any idea/instructions what the part number is, and how one removes it. The car is a 2007 Cayenne S, and it's the left front driving light (per attached picture). Cheers
