ok here's the deal..
i am driving at about 75mph and just chillin and all of a sudden ALL the warning lights turn on from left to right......from parking brake ...battery low...oil...lights...asr...abs....washer fluid...EVERYTHING! even some on the dash like the snow tire one...
I pulled over and everything seemed fine and the engine ran perfectly fine...but...
when i got home i check under the hood again with a light and saw a few frayed wires coming from a black cylinder type thing... i will take pics and post soon...but does anyone have an idea?!? i really need help guys! thanks in advance i hope ppl like supersec can help cuz out in PA we dont have dealerships...i would have to use a gas station repair type thing..
sorry for the length just realllllly freaking out!

 

My old 1981 Toyota Cressida would do this. We liked to have never found the problem. Finally took to the Toyota dealership. They traced it down to a bad relay in the fuse box that controls the lights. Mercedes probably has different things controlling the warning lights, but this was the problem on my old car. Good luck.

 

Did the gauges fail when this happened?

A few years ago I had a similar problem. The gauges failed (except the speedo as it's cable-operated) because the fuse contacts were corroded. However I don't remember the warning lamps coming on.

Whatever you do please don't take your Benz to a gas station! They'll hack it up!!!! There has to be a dealership or indie MB shop somewhere!

 

i wouldnt take it to a gas station for anything major but all they needed to do was install an alternator belt...

8) thanks for all the help thou !
