if you have vag-com you can scan the engine module and it should say somthing like this

Sunday, 16 November 2008, 17:56:25
VAG-COM Version: Release 409.1-S
Control Module Part Number: 8D0 907 557 P

the number in bold is the ecu code... or u can pop your hood and remove the cover to the ecu and take a look for yourself.
