Thanks, that looks like the one for the S3. The Gti has 3 different flywheels available one I believe is for the ED30 and has the same part number as yours. The other two I aren't sure about.
I rang LUK earlier and asked for the part number for a gti but they needed the last 3 digits from the chassis number, which I don't have cause it's an Octy and they don't supply for Octy's, even though I have checked the hole in the bell housing and sure enough it's a LUK flywheel!!
