Warning lights on dash come on after runing it a short period on

same problem here as well. I'm going to try and replace the ignition cylinder. Does yours start? Mine starts, but can't get out of park unless I move key to run (put in neutral) and start again, Issue dash is going crazy and running light are flickering. I noticed yesterday that the turn signal lever is hot, so it might be some short in the steering column

with the details that you have provided, it sounds like it may be either a ground, or ignition relay, but I've also encountered the same problem being the starter wire to the starter. The reason I think that is because of your dash lights coming back on .If you have use of a voltmeter you can test and see how much power is actually going to the starter An ignition relay could do the same, but usually won't interrupt the engine after it's running.

Yes it may be the wires are shorting or its actually the problem with instrument cluster.
Also get the vehicle scanned for any error codes stored in computer this will confirm whether is short circuit issue or actual problem:------

Don't you have some warning lights on your dash? MB cars are fly-by-wire that tend to depend so much on battery electricity when shut off. Use a high amps battery or battery recommended matching your car model. Check on some instruments that can be a parasitic drain to your car like, car alarm, sticking relays on auxiliary fans, radios. Worse you have a short somewhere or a wiring harness issue, but it should be giving you a warning on the dash.

Sounds like the alternator is going out the slow way.
Youre kinda lucky because almoat all alternators go out without warning.
Most Autozone shops or places like it will run a test for free.
Good luck,Gary

U can have the dash module rebuilt for around $200
here is one such source for repair

My Benz did the same and the cruise control would cut after a short period of time. If this is also happening to you,you need a Brake safety switch replaced.This is located behind you brake pedal.Go by a local Mercedes mechanic they should have one it's a common problem. You can put it on your self if you can screw in a light bulb! The warning lights will reset after a few engine starts.

I wouldn't drive it... when your brake light comes on, it means there's a serious fault with your brakes. They may not engage when you brake and there won't be any further warning other than the brake light

sticking valves. the short run of the engine free's them enough to enable runnig
