If you mean do mk4`s use can-bus wiring then no it does`nt. :D
 
Off to put my name down on a VCDS goups buy for a full function cable. I bought a Can only cable when I got the Altea as I never thought I'd need K line support.
 
Plan is to sell the Micro can which will part fund the new cable. Nowt like doing the job properly (which is what I should've done first time round innit).

Cheers anyway.:D
