Question about Mercedes-Benz E-Class
It sounds like a Wiring Problem. Kindly check all the Wiring and make sure they are well secured.
Note - The mechanical instrument cluster is an electromechanical module that receives most of its information directly from the various control modules, with the data bus.
The cluster includes:
1. A speedometer (10)
2. A tachometer (14)
3. A fuel gauge (2)
4. A coolant Temperature gauge (1)
A Faulty Instrument Cluster would also show all these symptoms.
Let me know, if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

Hello, not a good thing draining the battery which indeed will, I don't want to guess at this, but can give you some things that you can check out on your own to try and solve this.Mike, there may be a circuit grounded out causing this, but where you would have to have the meters and knowledge to check this out. What I would do, it to locate where all of you're fuses are for Instrument lights and dash lights and go from there. If you can let me know if the lights in question come on when you turn on the light switch, or the key would be helpful.If you have the owners manual, this will tell you the location of fuses and what they protect. Look the fuse block over for any signs of burned areas, etc. What is happening is, a switch that would be in a normally open position, (may) have welded the contacts closed sending voltage to the lights in question at all times. Locate fuses, there could be to locations, normally on drivers side under dash, and also under hood in a plastic box marked Elect. fuses and relays.You're owners manual will tell you as you should have to locations. You can also call you're local auto parts store and ask, or better yet, the Mercedes dealer. You can when you locate fuses, start removing them one by one until the lights go out.This will keep you're battery up until the exact problem is located. I know this is quite a long Temp solution, but just some things you can check on your own. Please keep me posted, Sincerely,

Hi there ...when you get the key out ...all those things should shut down ...so ..the problem its a short circuit .or a bad wiring .....but ...only those lights aren't enough to drain the juice out of the accumulator ...so ..those lights are the result of a contact to a bigger consumer ..that's in fault or just plane dead and its shorting your battery ... the way to fix it ..its to go b the wires...cause if its in error ..and has bad contacts no diagnostic tool will make any presumptions ..that can became real
