  1. I, too, have recently had moisture issues with the Driver's side headlight on my 08 GTS w/ Xenon lights. Every thread I've found about this, it's always Driver's side headlight. Hmm. I took high-grade silicone and re-did the seal around the headlight where the clear piece and black housing come together, pushed the silicone into the seam as much as I could. Had to move the rubber gasket aside in some places, but got away without having to rip it off completely. The factory black sealant looked like it was applied not evenly. It's been several months and a few decent rain storms, as well as driving in the rain, and no condensation has re-appeared so far. Good enough for now. I'll keep an eye on it and will probably have to bake & reseal the headlight if the issue re-appears. Unfortunately, my old ballast took on too much water and shorted out. When I took the poor guy off, there was water dripping out of the electrical connector. Initially it was not responding to Durametric at all, even after drying for 24 hr in silica packed filled bag, but it did start communicating again a few weeks later. Still, it just reported a bunch of codes about fried power components and the low beam did not function. Saga continues. My units were the "02" revision, so I would have to purchase a pair of the newer "03" units from Porsche as we know they have to be a matched pair. Unwilling to fork out $1000 for the parts alone, I managed to track down a matching "02" unit on eBay. It plugged in and low beam works, Durametric recognizes the unit, but it now reports that the VIN does not match and it needs to be reprogrammed at the dealer. Arghhh... VCDS does NOT "see" the headlights on the 957, and Durametric is useless as usual. Local dealer wants $175 for the 1hr of labor to re-program, and local indy is not far behind at $150. On a side note, I did pick up a matching set of 958 ballasts to try - they were cheap enough. The headlights turned on but the ballasts were not recognized in Durametric at all with the pair installed. Another interesting observation - when I had original undamaged 957 ballast on RH light and 958 one in LH light, it brought down part of the CAN network completely - wipers, radio, headlights all stopped communicating and acting up accordingly. Re-installing the 957 ballast in LH light brought the CAN line back up. Not sure if there's electrical incompatibility there or what, but so was my experience. Hope this helps the next guy here. I'm going to call my quest done at this point and make a trip to the dealer for programming. ~$320 all in here for the repair with used ballast. A-ok I suppose.
