X431 coding
Anyone else do coding with an X431 unit? I've managed to disable stop/start and changed the number of one touch signals from 3 to 5. Wondering what else can be done. I'd really like to have the default drive mode be sport instead of economy, as well as code flashing brake lights during hard braking, for example.

You can turn off the seatbelt reminder
stop the front seats from going upright when the back seat gets folded down (sedan)
On my W211 I was able to set the fog lights to stay on when the high beams are on; don't recall if I was able to do that to my W212 sedan or not...

Be careful exploring with LAUNCH as you can reset some modules and require reinitialization, often requiring other actions. Initializing/calibrating radar for Distronic+ is one such function.

If you want that done, you will need to have it programmed. You can make some configuration changes with LAUNCH X431, but other changes need to be done with programming. I recommend you contact @BenzNinja for programming changes. I had him reprogram my transmission to add Sport+ (a.k.a., Agility), last setting keep, and throttle tweak, and it has been amazing.

Some basic coding
- Disabled me connect (kept getting an annoying message, not being connected)
- Start/ stop disabled
- Five-turn signals
- Seatbelt warning, disabled
- Command startup volume
- Unlock and lock number of horn beeps
- Drls 100% brightness during the day, 70% brightness during the night
- Close the power tailgate with the key fob
- Auto-close the power tailgate with the door switch
It’s a lot of trial and error, and it depends on what your car is equipped with. I pretty much go through every module in variant coding and to see what can be turned on you might have issues, but it’s highly recommended to Back Up Code

Can you pls add LINKS to your post or copy of it since EDITS are disabled ??
I've tried tempering with my "ECO last "and "trunk keyfob closing" without success last time.
SAT Pm will have time to revisit
Thank you for organizing this research knowledge in addition to what JR started documenting.

That's NOT true, at least for my 2015 SL400. It made a HUGE difference in drivability. For my car, Agility = Sport+.

Maybe it wasn't you, perhaps it was Chris the swede or one other programmer. However, your insulting attitude has ensured I will never use your services. I've been on this site for 20 years. I'm an adult, I have never used tik tok, just like I will never use your "services". Get bent.
Edit: Oh look, this is where I remembered it from, my own previous research. So yes, you're a scammer who pays money to this site to ensure all critical information is deleted. Now I remember why I ignore you: https://mbworld.org/forums/e-class-w...-services.html . I will reiterate, get bent. Go cry to the mods.

Hey, after revisiting CGW, you might need to activate No. 042 code 890 (remote lift gate closing).

In CGW No42 code 890 was already activated
This creates an issue where the keyfob trunk button work great to close nut can no longer open. No ready for prime time...

I have checked to see whether I can do this for my 2010 s212 with power tailgate with my Launch Creader Elite 2.0 but I cannot see the Control Switch_1_vc. I can only see the Control Switch_2_vc in the list of variant coding. Any idea whats wrong?
Thanks!

If you can use Vediamo as Launch can't always can keep up with different variants of SW or HW used by MB, you can Flash the PTCM with the SW 2129025506.cff and all option will be available.
