Launch OBD and Stop-Start
How is it at reading and clearing codes?
Any suspension places to dig around in? I'm having an airmatic issue. I could take it to the dealer but also like fiddling...








Thanks for sharing knowledge. People need to learn all of that to avoid anyone getting accidently stuck with any nasty or greedy folks charging a ton of money to flip a code line. The BMW community long time ago started by few threads like yours so that now everyone knows how to work on their car. Your post above shows how straight forward it is.

I will suggest that this is the same here. It works for some (and its actually fun) but for the majority, commercial providers fill an important gap.

The Launch OBD device is not a "toy" anymore than any other OBD connection or device is a "toy". This is only being used as a derogatory term to scare people away from a tool that does the same thing a “coder” does, but much less expensively. He is trying to protect his own profit by deceiving people into thinking it's a “toy”.
“Once your original coding is messed up there will be no return. direction > dealer or BenzNinja”
This is just a deceitful fear tactic, again to scare people away from something that may effect his profits. The Launch OBD device allows you to save a snapshot of all of your original code that can be restored at any time. You can also take recovery snapshots at any time to revert to any point in time you wish. To say your only recourse is a dealer or BN is just simply not true.
“Coding is not a joke on MB and it's not code flipping like some deranged hater with 0 knowledge might pretend.
It required years of experience. BMW coding compared to MB would be doable by a 12yo kid.”
This is the biggest lie of them all. Exactly what “coders” do is the same exact thing these bidirectional scanners do. It is literally changing the options and flags that are already there in the code written and created by MB. Most “coders” want everyone to believe they are writing strings of code from nothing and using deep programming language knowledge and crafting boolean expressions, algorithms and formulas from scratch. That's not true. They are using a software interface to navigate through the existing code written by the programmers at MB to find the parameters they want to change by selecting alternative options that are already there.
It requires years and years of experience! However, I'm able to do it myself with no MB specific coding experience at all and I have not “messed up” anything. I must be a genius!





I had our M8 remote coded for $85 not only because its easier to do for me, they could also deal with features that BimmercCode couldn't do and most important, I wouldn't have to waste time and have a go-to person. That company also took care of our suspension, etc.
We must also have a very different group of BMW owners/friends

My car is a 2018 E63S 4Matic Wagon (W213.289). The X431 Mercedes software version is 50.26.
The “Operation Strategy_stop_start” option is not present in the PTCU section on my device, but rather in the ECM section. I have changed it to “Stop-Start Default Logic, Last Mode” and written the data, but the green light still comes on every time I stop and start the car.
I think the group of settings related to "3S" in the PTCU section have something to do with this, but I haven't been able to zero in on exactly how?
Any thoughts why the configurable item in in the PTCU section on your device but in the ECM section on mine? What version of the X431 Mercedes software are you running?




The scanner didn't work at all (diagnostic scan couldn't read any of the modules and gave unknown error message) on my 2024 GLE63s so I returned it.
I then got the Autel MK808S that's 3x the price. It's a lot faster at diagnostic scanning and worked on the 2024 SUV. Also found several DTC codes on various modules with similar invalid/incorrect/missing signals and got them cleared.
