Really depends on the make, you can get Mitchell and AllData prior to the subscription model (takes about a TB of space, from 1980s to 2013) to help with diagrams and disassembly and reassembly. Mitchell’s wiring diagrams really are a lifesaver.

Dealer level software/scanner combo you can get from obdii365, I got a Hyundai scanner from them and it worked well but you want to run the software in a VM or isolate it some other way and probably wouldn’t network it.

Vxdiag is pretty solid as well for the dealer software/scanner and you can usually get via Amazon but again I wouldn’t trust the software. I have their ford one and used it with IDS to set the VIN on an electronic power steering rack.

The software itself you can find via Google if it’s all you need but typically the scanner is very specific to the software for the dealership stuff

I too would be interested. Never thought to look for a pirated copy. Commenting so I can report back if I find any!

Edit - just install the search function on qbittorrent mate, search for “OBD”. There are dozens and dozens of them!

I had this problem around ten years ago where I wanted to be able to disable the esp (which prevents powerslides) in my VW Caddy. I found a hardware/software kit on aliexpress that went for around 30$. Maybe have a look there, I don’t know how new your car is and what model it is, but if somebody made an aftermarket kit for your car, there might be a cheap copy of that available from china.

Mine worked fine, I could disable the annoying option where the car always gives 3 consecutive turning signals, no matter how short you move the lever. Also daytime lights could be enabled, and whatnot.

Turning off the esp was not even an option with this board computer unfortunately so I had to interrupt the power line of a sensor with a switch to archive that, which I found out on an obscure German forum thread years later…

Ahhh stealing from small companies now?
