Welcome! Quite a jump from the mk2 to the mk5. ED30 is a cracking car - not long had mine, and a jump from a very heavily modded mkiv has meant I have had to learn all sorts of new stuff to understand the canbus, etc. Will be the same for you no doubt.
I do like all the mod cons on the mk5 though!
Put some pics up of your new Dub when you can!
