You're right, definitely need to practice on a few cars first.
Maybe as a follow-up question: you linked to a cheap OBDII reader that seems to be compatible with Android only. Looking on Amazon, there seem to be another product IOS-compatible: https://www.amazon.com/BAFX-Products-Reader-Diagnostics-Devices/dp/B078K54MT5
Is this the equivalent or am I missing a big difference? Also, I understand that it needs a third-party app to use it, any recommendations?
Thanks again for the very useful info!
Too funny you just posted this question. I researched this exact question today and bought an OBD2 about the time you were posting this. This reddit thread convinced me to go with the BAFX product for $27 for a quality wifi scanner. The LeLink^2 one was my second choice based off of Leaf drivers' recommendations but the selling point there was leaving it plugged in, which I don't plan to do. I just want to reversibly disable the VSP sounds.
