I ordered one. I had FVDI 2014 and 2015 before. This fvdi 2018 version has the same software versions as the 2015 version except that has updated software for VAG and BMW/Mini which is from the VVDI software. IMMO 4 and 5 key programming is working. Only tested on 2012 Scirocco 2.0 TSi and 2014 Audi A5 2.0T.

Mercedes software still has bugs for odometer correction. W204 did not work.

Overall it is good value for money. Not as good as OBDStar X300 DP pad for keys and odometer but has many better functions like programming and calibrations.
