Hello long time lurker first time poster, nice to officially be part of the forums.

I have a 2010 S550 4matic, January 2014 left it in my garage for 2 weeks when I went on vacation, came back rodents made a den under the hood and chewed up all my wires. Took the car to MB and get all the wires redone. April 2014 the first instance of my current problem occured. While driving all the error messages on my dash started popping up simultaneously, pulled over, got it towed to MB to fix thinking it's the wiring issue not fixed properly. MB tells me my front starter battery was dead and they charged it and it's holding charge and I'm good to go. No problems for the next 3 month until recently, it's happening again. While driving this problems occurs randomly, about 10 error messages pop up on dash including abs, power steering, air bags, blind spot assist, odometer, speedometer, COMMAND system shut off and restart. If I turn the car off and on the messages will disappear but will still be picked up by a scanner(10 noCAN codes and 4 airbag codes).

Can't go to MB this time because they are backed up and fully booked until October and I have a big client coming down on Monday and she likes to ride in the S550. So I took it to my local mechanic to diagnose, according to him the starter battery is fine, the smaller secondary battery is also fine, the wiring is fine. The only issue he could think of is instrument cluster software requires an update and that's why I'm getting these messages randomly.

Anyone had same/similar problem that can share some expertise?

Thanks in advance.

Left it at McNally's 2 days ago, we still can't figure out the problem.

If MBUSA - repair is warranted for 12 months/unlimited mileage I would suggest speaking with service manager requesting to expedite revisit explaining your client situation and this will be the third attempt to repair.

Call around to different MB Dealer Service depts. Also call MBUSA and talk to their tech support, they might be able to consult advanced technicians. Tell all of them you have a business deal brewing that one of their company's cars can assist in making a great impression.

I'm located in Toronto, Canada, does it help the situation if I call MBUSA? I left my car with Mcnally's which is one of the top shops for MB some say better than dealership. Guess I'll call them and see if theres an update tmr, as for the business deal, client brought 7 figures with her from China to invest in my company and so far she hasn't mentioned investing like we previously discussed in June, Asians. I just need my car back.
