FYI I bought an Autel MK808S for my 2025 GLC 43 AMG and today I was told none of their units can access the 2025 models because of some sort of gateway issue implemented by MB, the box connects and does very limited functions definitely can not do recoding only reads faults, and they do not know when the fix is going to be available and have to call them periodically, so had to return the scanner.

Besides @EleBest nobody can do coding on latest generation of MB.

Autel or Launch is the most dangerous scanners for MB.

​​​​​thanks, all I wanted to do is was to go into the ECM and turn off the ECO Start/Stop feature for now.

The ECO Start/Stop is not in the Engine ECU from mote than 10 years.

That's not normal on MB, here we activate the "Last Mode", like a memory, so the function will be always available if the user will want to use it. If you code "not available" on something that's available some other energy management feature will be impaired.

Ok thanks well this is my first MB, the ECO start / stop is very annoying, the other thing i learned on GLC 43 models remote contraol fob does not reset seats to the driver via remote, our old BMW did do that and now after my wife drives the car I have to move the seat back manualy, the most stupid setup that I never expected from MB, I also hear that on 46 models it does move the seats via the remote.
