There are two ground points under the hood, one on each side for each set of lights. Usually on the front side of the fenderwell, it's just a small stud (4mm?) with several brown wires coming to lugs that are stacked on the stud and secured with a nut. With the key in your pocket, remove the nut, use a mild metal-bristled brush on the stud, lugs and underside of the nut, and then reaffix them all, tightening firmly.Check Codes, where are all of the chassis ground on the W208? I've asked this question before on forums trying to (possibly) track down my 'dimming lights' issue, thinking perhaps there is more than the single main ground in the trunk/boot off the battery. Checking/cleaning others if they're large/major points of contact is my next step, but I've never heard anyone who can tall me what points these are. Thanks!
Hallo!I had a pair of halogen bulbs burn out 5 months ago, and now they burned out again. Both times, one went and the other immediately followed. I've been told that a bad ground could be the problem. Is this possible? If so, can someone explain to me how a bad ground could shorten the life of a bulb. Any other suggestions?
