I own a 2011 C300, currently the RIGHT SIDE LOW BEAM IS OUT. HIGH BEAM works just fine. I have switched over the Left Side's Low Beam bulb to test out, which works fine. Both bulbs works fine. My Right Side Low Beam won't turn on and the message is popping up to "CHECK LOW BEAM". I had replaced every fuse possible in the front fuse box. Took the car to DICK'S AUTO SERVICES to run a test, they still couldn't find out what's wrong with it. They called me back asking to charge me $300 to take off my front bumper order to test out the "MODULE". Is this step really necessary? I need help!!!
