Found myself in need of a fault code scanner for a non VAG vehicle (Stepson's Vectra C) so did a quick check of the online stores. Found and took a gamble on a new model, VXDAD AM3011 for about 25 on Amazon. Did exactly what I needed, read a fault , told me what it was (
as a code and text description)
and reset the EML with no probs after I fixed. At the price, a colour screen simple button user interface and takes it's takes power from the OBDII port, already paid for itself on one fault.

I should say I have no link to this Chinese manufactured product or the UK vendor and I am also a VCDS/Ross Tech user.
