Manual shift mode for cars w/o AMG Sports package
some of you might be interested in retrofitting manual shift mode in one of the following models:
- E-class w212 / s212
- E-class Coupe / Convertible c207 / a207
- C-class w204 / s204 / c204
- GLK-class x204
All your car requires: the colored DIC / Speedometer.
In order to enable the manual mode your dealer has to add two or three codes in your VeDOC. After doeing that, After doing that, he has to SCN-code your gearbox AND your Driver Information Center.
The result (acceleration from 0 to 159mph - yes, I switched my DIC to mph just for you guys - and at ~0:45min acceleration at WOT in Manual mode - 4th gear and NO downshifting even if going WOT without Kickdown).
It tells you to pay attention and shift your own gears. In the video, the M only shows when you explicitly select a gear.
I don't know what you are talking about here. Are you commenting/exclaimed/surprised that all W212 can be converted, or are you saying that all W212 sedans, wagons, and coupes have a full fledged manual mode? If the latter, than you are wrong. The paddle shifters in my 2012 E550 sedan only specify the maximum gear to use, not to hold a specific gear like a true manual. His 4th gear pull in the video is a great demonstration of how the transmission in true manual will function. It doesn't kick down to 3rd or 2nd as a normal W212 would after "paddle selecting" 4th. It just keeps the car in the current gear even with your foot on the floor.
If you don't believe me, read your manual as it explicitly states this "maximum" gear behavior.
- upshift on redline
- downshift when RPM reaches idle
- downshift when going beyond the kickdown-poin
However, it gives you 100% control over the gearbox between idle and redline without unwanted up- or downshifts and you are still able to get maximum downshift when commanding a kickdown for safety reasons.
Costs: Well, it depends. As this mod is not officially certified by Mercedes, one can not find it in any pricelist. Therefore it is up to the dealer IF they do it and how much they are going to charge. My dealer billed me less then 50 € to code "M"-Mode, code Homelink to my VeDOC (which I retrofitted) and to install an electronic vehicle log.

My car came without homelink. So I bought a inside rear view mirror with homelink (used) and mounted it to the car. To make sure to get all updates, I made my dealer to add that code to my VeDOC.
Electronic vehicle log: In Germany we have to demonstrate, which routes were driven for business in order to make them business expenses tax wise. This is the reason why I bought an GPS based vehicle log. My dealer installed that into my right cup holder for me.




What does it take to get this mod on a MY2014? What does SCN-codeing the transmission and instrument cluster mean?
unfortunately I am not sure if this is going to work on an 2014. It does work on 2012 and 2013 E-Class and all w204 Facelift. I'm afraid, but somebody has to try that out.
How do I toggle between those modes? Did you check my first video? Next to the COMAND Controller, we've got that "E/S"-transmission push button. After enabling "M"-mode you can toggle with that switch between E/S/M. Of course you could replace that button as well - however that would take approximately 130 €...so I did not do that as this is only for show and has no influence on the function.
SCN coding: For info on that one you might want to google on Software Calibration Number. It basically works like that: Mercedes goes online and gets a number. They download that number, and place it in the desired control unit (for example the gearbox). This number sets options and so on.
So by SCN coding the transmission and the cluster Mercedes just tells those computers, which options are being installed in that specific car. That means: After updating VeDOC with the mentioned codes (AMG Pakage, Sports Steering Wheel, Shift Paddles and so on) one will get another SCN for transmission and instrument cluster. These new numbers will unlock the desired features.
I hope that helps.
From what it appears the paddles should automatically function as a gear limiter but require the above coding for manual operation. At least that is what appears to have happened for people swapping out with older models.
A local shop that can do SCN codes said this wasn't possible as it would require a new CAN gateway, steering module (isn't that in the wheel?) and some other module. They made it sound like a ton of hardware would be missing from the car.
I would still be lacking a button for full time M mode but that's not something I'm looking for.

Thank you.
My question is I have a 2009 E550 (W211) and would love to enable the true manual M mode on it. In your post you said this might be possible for me. Do you know what settings need to be toggled in Das developer? I have offline coding.
Do you (or someone else) know if it is possible to somehow make the IC to display what gear you are really in while driving in C and S mode?
For me personally knowing what gear I am in would be helpful. W213 E class shows what gear you are in, but W212 doesn't.
