Hi all, new member here. I have a 2010 W212 E-350 with build 608 and 615 Bi-xenon with curvelight technology. About July I got "Adaptive high beam assist inoperative" alert on dash on several occasions. I later realized that the driver-side headlight would shut down after 30 seconds of turning on. After several weeks of searching the internet I determined that the command module or computer shuts down the bi-xenon bulb if the motor controlling the high beam "hood" malfunctions. I found youtube videos on separating the clear lens from the headlight body and also repairing the motor. This seemed like a good alternative to the $3000+ MB dealership cost to replace the light. My problem is and hence my question: my clear lens will not separate with a heat gun no matter how much heat I apply, so is this a newer type of non-heat sensitive glue and if so, what are my options at this point. I can't believe it's going to cost this much for one headlight and in a few months if the other one goes out it will cost more than the car is worth.
