Permanently Disabling Auto Start/Stop (Eco Mode) on 2024 GLC 43
I’ve successfully disabled the Auto Start/Stop feature on my last three Mercedes-Benz vehicles by using an OBD-II module from a company that offered it at the time. However, I haven’t been able to find a similar solution for the 2023 or 2024 GLC models.
If anyone knows of a company currently selling an OBD-II module for this purpose, please let me know.
Additionally, would it be possible to take my vehicle to a privately owned Mercedes-Benz service shop and have them disable this feature using their scan tool?

Many forum members including me have coded off start/stop using the Launch OBDII scanner -- do a forum search on this. There's another forum thread that discusses disconnecting the alternator LIN bus, which kills start/stop as a collateral benefit. Lastly, BenzNinja can do this for you if you don't like the first two options.

One man's damage is another man's benefit (lol). I got lost a couple dozen replies into the 764 threads.

Talk to Vlad, he'll hook you up wit an OBD fix. He not only turned off the ECO Start/Stop for me, he enabled the multi-beam headlights (which on the 2020s were disabled at the factory). He's a good guy, many many many people have used him for this.
