Seems to be a lot of conflicting info from years ago and not much lately.
I've come across post of people saying they've plugged in an obd module paired it with forscan and pulled/cleared codes with no dramas, others have said the protocols don't work or they've had dramas with it. Is this a past problem that forscan has learnt to deal with? Seems like one of those utfse things but I'm not able to find anything recent on it for au.

Forscan works on AU3, similar on AU2, not sure AU 1.5 & i don't think it works on AU1? [but not 100% sure so may be wrong]. some of what i have read is it won't work as per [say] a BA but should still give codes. my AU2 wasn't around long enough to test out Forscan on it.
