You can use OBD2 dongle to change default setting of lane assist to be off by default (after car starts) And many more setting that are decided for you as if you were using a rental car not your own. Like always reseting air conditioner to 22C after starting a car. God dammit i want 20C. Let it stay like that when i start a car.

Colour me skeptical. ODBII is just a protocol; it knows nothing of the modules on your buses. I think you will find you need the dealer software. Tools exist that implement big chunks of that functionality, but since they are built on reverse-engineering, the price approaches the dealer software anyway.
The only place i found the Mercedes software was a paid forum that obscures the links. Getting the cracks working was a magic incantation. It's similar for VAG. They won't sell you the software if you're not a dealer.
You will not get there with a £40 ebay special. If you can, please share what works, it will be of much interest to many.
You're correct that the dongle only facilitates the connection, but you don't need dealer software. I have an ODB dongle and a £20 (I think) app on my phone which lets me change a _ton_ of settings on my BMW which aren't available in any in-car menus.
Bimmercode lets you do coding (it's very powerful and you can easily mess up your car so you have to be very careful with it), and Bimmerlink lets you read fault codes etc.
Thanks, i learned something new. I think we're both right by degree. That app is more functional than anything I've found, but there comes a point where you need someone to tell you the modules and fields or you risk bricking your car.
Oh for sure, but you can do a lot of things without ever touching the advanced coding section. It's definitely worth being cautious though - as you say you can definitely brick your car with it if you're just YOLOing your way through it. It does back up the module configuration prior to writing the update though so you do have a safety net.
not affiliated. have used ODB eleven on my vw eup (2021). They have curious payment strategy. Basically you buy tokens and then use them for each enable/disable operation.
