Not strictly true.

I bought one through ECU and OBD II Vehicle Diagnostics - Scantools and Code Readers - Home Page and it has worked on a MK5 GTi Golf. He doesnt list them on his website but drop him an email and he'll sort you out for about US$80

Phil of course its true!! :P

The A5 platform requires a CANBUS cable. You cannot get licensed VAG-COM to work on a third party cable with CANBUS

Get the proper VAG-COM License with HEX-USB+CAN Interface from Ross Tech. e-bay ones will not work with Octavia II and by the time you license the older version which these work with the cost is not that much more.

We ordered one from Ross Tech, delivery was very quick - you will have to add VAT and duty to the price (17.5% and 3.3% respectively)

What does this cost in total ?

I have lots of little things i want to do, but can't find a local Vag Person and the dealer will be a wasted trip

Follow the Ross Tech link Ray, it's cheaper to order from the US.

You can get a MicroCan which is ideal if you only want to do CANBUS cars which is cheaper than the full HEX+CAN

Please can you tell me where I can find a list of what can be altered and read with a MicroCan on a May 2006 Octavia 2.

The list will grow -
