I think you are immo3 mate, best way to check is to see what side your immo symbol is on.
You need VAG Tacho to extract the codes from the clocks and to change the mileage which VW can't do any more. Also immo3 swaps are a bit more involved as you need to match the ECU code to the clocks whereas immo2 to immo3 is quite easy and takes about five mins
