has it got a different engine cover or anything different to look out for, also guys where is the engine no and chassis no located

[xxx_mojo_xxx]

The chassis no (or VIN no) is visible in one of the bottom corners of the windscreen.  Not too sure about the engine no... never bumped into that.

Only thing I can think of visibly is the ED30 will have a tube/pipe running down the left hand side of the engine cover as you look at the car, this is running to the Diverter Valve which is located at the front of the engine on the ED30 unlike the regular GTI which is bolted to the turbo itself down the back of the engine

Can't remember exactly where, but around the front left corner as you look at the engine near the cambelt cover to head interface, the engine type should be stamped into the casting.  BYD is what you are looking for.
