My C63S coupe has lost the individual setting about 5 times, anyone else have this? I will try to put the car into individual, but it doesn't let me go "up". If I turn the car off and then on again, I can go into individual, but the settings are lost, they return back to stock, and I have to redo them. Getting annoying. Anyone else have this problem?

SBH-

first time I hear about this ... unusual

Haven't faced this problem yet... Might be a software update issue

dviolagis

I have the same problem. Have you had this issue resolved?

jkob5

Unfortunately no, I asked a mercedes master tech about it and he had no idea how to even go about looking into it, as everything else that is memory stays and it's only intermittent.

That's really obnoxious. Not something you should have to deal with on a new almost $100k car.

Same problem here!!!!

Did you go for the Mid City Engineering mod, or is your car still stock? Mine arrives next week, and I expect to be using individual mode all the time. Important to know why this is happening.

auditoamg

Yes, but they are unrelated. The mod doesn't touch memory. It only puts it into individual mod, the car takes care of the rest, I believe...

This used to happen to my sedan all the time. Individual settings would be erased sometimes and other times I would not be able to access the individual settting. It went away. Can't pinpoint it to a service, it just stopped. No MidCity mods.

Any have resolution on this?

jkob5

No but I have a little more info about it. Sometimes when I start the car, the screen stays black for about 10 seconds. During this time, some of the interior dash lights are not on and the green light on the eco button doesn't turn on either. When this happens, I can't get into individual mode. If the car is turned off / on again, I can get in but individual settings are erased. So it has something to do with some of the car electronics not being initiated correctly on some starts, no idea what the reason is though. My car will be fine for a couple of weeks and then do it everyday for a couple of days.

Your discription of the problem is identical to mine. You describe it perfectly.
I sent your description of the problem to my dealership so they can figure out the solution.

My 2017 C63S occasionally drops the Individual settings exactly as OP says. In 3300 miles, it's probably happened 4 times.

4 days in a row

I have had one off incidents in my coupe which resolve themselves when shutdown and restarted.
radio device not found.
heads up not working.
mirrors don't fold out when I unlock the door.
had my car almost 3 months. I hope that's it they say all things come in 3

Dealership diagnosed problem and determined I need a new COMMAND Control Unit. They need to order part. I will let you know if that fixes problem.

auditoamg

Dealer blamed low battery voltage, which I know is bull****. My coupe has also lost radio settings, parking lights and climate control presets

jkob5

I think your car is the only one losing all those other things, yours might actually be a battery problem

auditoamg

Maybe, but I had to hunt to find they had been lost. And when I say lost, they just reset and the CF card index had to be constantly redone before playback....

I have the same issue. It seems pretty random but sometimes it happens when i remote start the car with my phone. I mentioned it to my dealer and they are going to look into it next time i'm up there.

dviolagis

I just got my car back. Paper work reads as follows: Internal Fault PTSS Case #95139. Replaced Command Unit. Part number DVD-ROM 205-827-80-00 and Control Unit 205-900-86-30. So far so good not problems.

auditoamg

Does this imply there's now a bulletin??

dviolagis

Not sure. I just *****ed and complained enough to get it fixed.

I have same issue with random loss of my Individual settings. Had service tech look at it. They were unable to duplicate it so they had no idea. Apparently, no one else locally has reported the same issue.
