he's got a mk3.
the second one is clearly out, mk4 is the earliest it can do.
the first not 100% sure but don't think vag tacho can do anything on mk3, since the immobiliser is not in dash...
as i've said, if you come to malvern i can do it for you.
VW will give you the 7 digit code if you tell them the immobiliser ID code (this can be read with vcds - even a demo version).
all you need is this code (plus dealer id and date) and obviously a new key with the rfid chip inside. see ***
if you're a bit flexible i might be able to meet you somewhere after one of my jobs at a services (travel all over midlands for work every day)

Write down the 14 digit Immobilizer ID number (from diagnostics; this would normally be something like VWVZ3Z0Txxxxxxx)
Take that ID number to your dealer and request your seven-digit SKC, along with the workshop code and importer number and the date it was retrieved by the dealer (all this information can be found in the upper-right corner of the Administration screen of the dealer's VAS 5051).
