My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

From what you have described here with this fuse being pulled dropping the draw to normal as well as the draw not coming back at all over night after reinstalling this fuse indicates the fault is in the instrument cluster itself.The instrument gauge cluster is a computer of its own internally and it can fail/act up and causes this type of fault here with the cluster itself needing replaced.I have had to replace and program the cluster before on this model as well as other Mercedes models to correct issues with a battery drain like you see here.

The cluster is not fully powering down properly with key off causing the drain.

thanks Pete, but is it repairable?
Expert:  Pete replied 29 days ago.

I apologize for the delay as I was offline the last couple of days.

Usually the cluster has to be replaced to resolve this type of fault here but in some cases if you can locate a facility online they may be able to repair it.I would just make sure it is a reputable repair facility to do the repairs.You might contact the facility below to see if they can look into and repair it for you.
