I've seen this posted once, but mine has gotten so bad it's now effecting air conditioning, and today even my DRLs didn't come on.... Mercedes in Germany wants to blame my mid city engineering module, but I had the issue before it was installed and I know others who have this problem do not have this module at all.

Mercedes also claims I'm the only complaint thus far. Please, if you have had this issue, please tell your dealer. My dealer has been awesome about this, but Germany needs to get on board.
