I checked my rear light clusters today on my phase 1 and I found a load of water had been leaking into them from the boot and had stopped the rear indicator on the drivers side from working, there was a huge build up of white sort crap on the bulbs and the bulb socket on the reverse lights and the indicators. Has this happened to anyone else? I cleaned it with some wire wool and solved it but it did turn into bit of a pain. any suggestions to stop this from hapening again?
