Thought I'd start a new thread for the 2005 and later VW models and heater cores. Having a MK2 GTI, its a beast of a task, dash out, whole heater module out and like many VWs a massive pain in the (_!_)
HOWEVER!!!
If the plumbing into the heater core looks like this, then you might be in for a good surprise!
You're probably good for a "dash in place" removal.

WARNING: ENSURE YOU DISCONNECT THE BATTERY !!!
DIFFICULTY: Moderate to mild.
NOTES:
So the first thing you'll want to do is remove the RHD drivers seat, center console, foot support and under dash trims.
Pull the carpet back a little and remove the side brackets to the console support. This will give you the clearance to swing the lower tray out.
I had to remove the Air Bag ECU as the picture in the workshop manual shows a lot more head clearance that I had. the lower part of the heater box housing was almost resting on the airbag ecu. Three 10mm plastic nuts and the disconnection and it was out.

WARNING: ENSURE YOU DISCONNECT THE BATTERY !!!
DIFFICULTY: Moderate to mild.
NOTES:
- The seats have spline drives to bolt the rails to chassis
- My seats have airbags and they need disconnection (two of them)
- I removed head rest and leaned seat forward max to get the seats out
- Air Bag ECU required disconnection and has a press tab and level
- There was another connection to allow the lower half of the heater housing to be removed.
