Afternoon All!

Does anyone have any specifics on where exactly is the memory stored for the seats?

More specifically, I have a Edition 1... the memory seats works BUT instead of taping you have to hold it until it gets to the stored position

My wife has a 2020 CLS450 and you do not have to do that. One tap and it positions the seat to the stored values.

Is this part of the seat controllers or another module?

Strange because the E-Class and above have it one touch and it will set the seat position until it returns to the preset position, the C-Class and below you have to hold it. Weird yours is not just one touch.

They changed the behavior for our model in 2019. Each model got one-touch memory seats on a different schedule.

this is how it is on my BMW, what I do is I crack the door open while the car is off and then I hit the position seating that I want and then it will automatically put everything to the right position but once I start the car if I press that button, I have to hold it to keep everything moving into the final position. Therefore, I just keep the car off put the position I want to and then once the car is on, it'll continue to adjust the position to my position.

Weird. I just sit if I have my phone on me, it would adjust automatically and if I don't have my phone on me, I just hit my name on the screen and it does it automatically.

Interesting is it only the E-Class or C-Class as well?

What could it be? obviously not digital key but did it choose your profile automatically based on the bluetooth connection?

I believe all models now have one-touch memory seats. But some waited years longer than others for some reason.

It was never an expense issue. MB considered it a safety problem for the seat to move unattended, in case a child was caught, for instance. Apparently the marketplace convinced them that they were being ridiculous.

Oh that is nice so even down to A-Class? I was curious because one touch to adjust seats makes so much more sense than holding. Unless you want to stop at a certain position but then if so why not just adjust it with the seat controls instead of restoring the memory position?

so the question becomes,

Is that stored in NTG? Seat Module? Other comfort module that has not been mentioned?

not sure but it is definitely not NTG because when you reset the infotainment (factory reset) the seat memory still retains the same data.

I'm not sure but i strongly suspect the behavior is determined by the seat module. I also believe that 2018 and 2019 cars use the same module and the behavior is set by flashing. You probably won't get a dealer to flash the 2019 behavior for you but a third-party that specializes in such things most likely can.

I have a 2018 and I can confirm one has to hold the button until the seat/mirrors/steering column are fully repositioned. It would be well worth it to have it reprogrammed to be one touch.

Maybe the third party coders might be able to do it.

On my 2017 I found strange that you had to hold the button until everything has moved into the stored position.... thought MB was better than that.

Even my 2006 Chrysler 300C (Dodge Magnum in the US) had one touch positioning.

+1: yes, exactly!

I think it is designed that way likely as a safety.

That way seat stops moving as soon as memory button is released.

As mentioned by another forum member, after 2019 (including) model year, it is one press and release, MB might had complaints about it so they decided to change it.

Except customers won and got their one touch move back

Mercedes used to take safety to an extreme -- almost to the point of paranoia. Having to hold the button down while the seat adjusted, lest a child stick a finger in the rail and get pinched, is just one example.

You can close all the windows and sun roof with the key fob. You still have to hold the button to complete the operation, but earlier key fobs were specially designed to only allow this operation from a limited distance. The key fob had a special infrared transmitter in addition to the radio frequency system that operated everything else. The door handle had a dedicated IR receiver too. This additional expense and complexity was so that you couldn't close the windows without seeing that there was no child in danger.

Our cars allow opening and closing the trunk from the driver's seat. Older models would only allow remote opening. You had to close the trunk directly, to make sure nobody was there to get pinched.

The market finally forced MB to take a chill pill. Their paranoia about pinched fingers had to take a back seat to the competition offering more convenience.

I just hope they don't compromise actual safety that protects the occupants because customers complain about the nannies.

I have a aftermarket add on on my C7 Corvette that allows remote opening/closing of the windows with the remote. It is so convenient I would easily pay $1K to add it to my E63S. Heck, even at $2K I'd waffle for a while and then pony up. The OEM IR thing MB did is effective as a frustration increasing device, but worthless as anything else.

Are we thinking about the same thing? If so, are you talking about the summer convenience opening? You need to point the key at the driver side door handle, it works most of the time for me. Got to hold it of course. Usually it opens the sunroof first before opening the windows, it will take time such as the sunblind opening, so you should pay attention to see if the sunblind opened to determine if it was working or not.

Summer convenience can also be activated by unlocking the driver side handle and pull it a little out then holding it (can't remember the exact way since I mainly use the remote), to close the windows back up, you hold the square part until it responds and keep holding it until you have closed the windows, did you know that is what the square was mainly for, for the summer convenience opening? You usually lock the door from the outside of the square, yes touching the square locks the doors but you technically should lock it by tapping the outside of the square.
Here is a good explanation: https://mbworld.org/forums/c-class-w...ml#post9163135

Found the proper procedure I was looking for: https://mbworld.org/forums/attachmen...918d1500297621
Page 9 "Summer Opening and Convenience Closing
With KEYLESS-GO
Press and hold your finger on the ‘lock’ sensor on the door handle for 5 seconds.
Then, continuously pull on the door handle and the windows/sunroof will open. This
will also activate the ventilated seats if equipped"

In the Corvette it is like this. Drive to restaurant. Car is outside in the sun for 3 hours. From inside the restaurant while paying press the remote unlock 3X. Windows roll down. By the time I get to the car it has cooled off enough it is no longer a furnace to enter. Obviously there are security considerations, but as long as it is in sight and if someone gets to close then just press lock 3X and up go the windows and the doors are locked. All this can happen when you're 100' away.
Comparatively, the MB method to the Corvette is like driving a Prius vs a E63S.
