I've had error free LED sidelights fitted to my c180k coupe for about 3 months now with no problems what so ever. Suddenly I've noticed the drivers side only has stopped working. I've searched the forum and elsewhere online and cannot find a specific answer. I've swapped the bulbs round and at the moment it only seems to be the drivers side not working. When I unlock the car it flickers and sometimes doesn't come on at all. When I'm driving I've noticed it's out completely. Has this happened to anyone before? I'm now getting an error message but the bulbs have worked fine with canbus for 3 months and now only one side is causing problems and when I swap the bulbs over its the same side causing the problem. I really appreciate if somebody to solve this for me. Thanks.
