I have a rainwater leak which could be coming from the o/s outer rear light, rain water is partially filing the cubbyhole with about 50mm of rainwater, I have dried out everything, and put crunched up paper towel below the rear light, and towards the front of the cubbyhole more towards the fuel filler cap location, after soma rain with the vehicle sitting on the driveway, I found the paper towel under the rear light soaking wet, and the other paper towel location bone dry, I ordered the bmw rear light seal kit, ready to replace the seal if that is the cause, but can't figure out what holds the light in place, I can see one fixing nut directly behind the light, which I removed and possibly another hidden in a deep recess which I have only partially removed, the light is still firmly fixed with no movement at all, so my question does anyone know how to remove the light, and indeed if that's where the rainwater is coming in, I have come across this topic on other forums of water getting into the cubbyhole on the F11, but unfortunately they don't say the cause or the remedy they found, so I'm hoping someone can shed some light on this topic, thank you.
