Hello. Firstly sorry for my bad English. Recently I have bought FVDI 2014 from aliexpress for volvo dash flash reading and writing. I know that FVDI 2014 can do it perfectly. BUT. I've received non working FVDI. There was a circuit in the hardware between - and +. OK. I have found problem and fixed it, and now my FVDI 2014 is working, but only with k-line. I'd like to know, FVDI 2014 is too old for CAN bus, and should I purchase newer FVDI for CAN cars, or there is a problem with mine and FVDI 2014 should work with k-line and CAN protocols? Thanks in advance
