I saw a mod where there was an arduino/lcd setup on the dash of an Audi to turn off the ESC and other annoyances on startup.

I turn mine off quite often. On dirt roads and snow.

Yeah, there are ways if you figure out the manufacturer specifics. Thought it'd be fun to try capturing and replaying CAN messages, gave up cause whatever cheapo CAN to USB adapter I got wasn't working with my Linux laptop. Probably could've figured it out but decided it wasn't worth risking my 2005 Quattroporte with something that was feeling increasingly jank. Autel scanner already gave me all the read-only access I needed, including clutch wear.

I recommend "the car hackers handbook".

Gives you all the info you need including software.

Great start to knowing what the CAN is doing.

That one is good. I did actually start there, just bought the wrong stuff :S
