Sorry,can't help with yours.
Myself,just bought an Autel VAG405 reader.Reads and clears most VW codes.
Autel
It's not perfect,
Has USB cable too, but unit is not sensed by PC.(I'm guessing it needs an external +12V supply as USB is only +5V)
(Doesn't read Toyota Hiluxes either, in generic OBD2 mode)
$50ish on Amazon
