Yes it is £200+, the software is free, but the rosstech software will only work with their rosstech ob2 lead which is £200+ to buy..
If you have a cheap ebay lead then i think you can get vcds lite

Can I use an Interface adapter that came with another software package?
The full (non-Lite) version of VCDS is not compatible with 3rd party interfaces at all, even in shareware mode and vehicles that use CAN-Bus diagnostics require a Genuine Ross-Tech CAN-capable Interface. To use the full (non-Lite) version of VCDS, you need to use a genuine KEY- or HEX-, or Micro- series Interface purchased directly from Ross-Tech or from one of our authorized resellers.
If you have an older car which does not require a direct CAN connection for diagnostics (typically cars made before about 2005) you may be able to use VCDS-Lite with a "dumb" ISO-9141 (K-Line) interface. Ross-Tech has not sold interfaces like that since early 2004. In the late 1990's and early 2000's, there were a number of software packages sold which included interface adapters which are compatible with VCDS-Lite. If you can get VCDS-Lite working with one of these, we'd be happy to have you register the software with us for $99. We will then provide support for the functionality of the software -- but not for connection problems.
Most generic "OBD-II" adapters will not work and ones that use ELM chips will definitely not work. If you have some interface adapter of unknown origins, there's generally no harm in trying it, but please keep in mind that Ross-Tech is also not in a position to provide start-up support if you're using any interface adapter that you didn't buy from us or one of our authorized resellers.
