Dash display went crazy
Last week a customer came to my store in 2015 ML350. They had bought lunch at a fast food place and were sitting by the docs with car running and AC on when the got the messages ESP not available and speedo went full scale and push button start quit working.
yesterday I had basically the same thing happen to my 2009 GL450 while eating lunch with the AC on high.. In addition, the outside temperature on the dash showed 120 degrees although it was only about 80 outside.
Has anyone else had this happen and what was the cause. I have a feeling, actually I hope, that it is a bad battery.

I see a trend. Eating lunch in the car with AC on. I'd stop eating lunch either in the car, or with the AC on. Just kidding.
I think you're on the right track. Look at and test battery first. How old is the battery?

Battery access is not as easy as other cars under the hood, but not terrible. MB could have stuck it in much worse places. If you have a scanner handy, you may be able to read voltage values with it. I use an iCarSoft MB II. The V8 module data stream is where I can read the voltage before crank, during crank, and the car running. You can also measure with multimeter at the contact points under the hood (front passenger for the left handed drive specimens). To load test, not sure if you can use the contact points or not.

I can't convince my wife to eat in the car most of the time. She prefers to dine in. I prefer to chow and drive, just to make headway and not lose an hour. I eat to live, she lives to eat.

We are driving cross country and she wants to stop, eat and shop. I want to get there this lifetime.

To get to the V8 module, instead of auto scan, select Manual and I think it is on the second page, or maybe first? Go intoGthe module, then live data stream and select the idle or cold start option. They're the first two on the list. Then look for the voltage, may need to scroll a screen or two. You have to have the dash lights on to get into the live data. Dash lights on, motor not running, (two presses on the push start without the brake engaged) gives you pre crank volts. For the crank voltage, keep a close eye on the volts as you start the car. You'll get the lowest voltage your battery sees when you're cranking. Mine goes as low as 10.8V, IIRC. Once you have the car running, the voltage should be 14V+. Mine is between 14.02 amd 14.12V (alternator charging the battery).

Mine is not crazy about shopping, but makes up for dining in. Like you, I just want to get there and prove the GPS wrong about its initial timing. Sometimes I wonder if she's in cahoots with the GPS.

Service C
Also wanting to find out what a "Service C" involves. Dealer was not much help. He suggested I bring the car in, but would not say what a Service C involved or give me a price. Since the nearest MB Dealer is over 4 hours away I would rather do it myself or have it done locally. From what I can find online it is nothing more than an oil change and fluid level check. If so, how do I reset the system to recognize the service..
Another question: is there a update for navigation on the command center? So many new roads that it doesn't recognize.
