... I found it on Seth's github  (https://github.com/sambthompson/SAAB-CDC/releases/), loaded it, verified it and everything seemed okay.

Just noting here that this repo is mine, not Seth's (his github account is https://github.com/Edison517), and mine is not the official one. The "official" repo is at https://github.com/kveilands/SAAB-CDC/releases/. My fork is a bit out of date vs. head, although it does work (mostly). Current issues I haven't got around to sorting include a problem where excessive inbound CAN messages cause watchdog timeouts and hang the unit (since it can't restart without watchdog timeout being much longer). Enabling Open SID on your ECU creates the conditions to trigger the problem. Unfortunately some watchdog fixes I applied early on were lost when another dev took over.

Also, power management is non-existent, so if you don't drive you car regularly, the drain will kill your battery. There are options for sleeping the RN52 and Atmega328p, but I haven't got around to implementing yet. Additionally, there is no proper bluetooth security, which I'd want to have before putting any track data from bluetooth onto the car's CAN bus. Obviously these comments only apply to versions before v6, when the STM32 switch happened.
