Thanks for sharing, I always love a good tune vid.
The 3.0t in the TDI is a proper "V" engine, however. The VR is a single head staggered in line (same firing order as a cummons or in line engine). The intake and exhaust runner lengths vary on odd versus even cylinders due to the wide head. While the total airflow travels through the engine and out the tailpipe the same distance, it varies on the intake or exhaust side...this is why VR6 motors sound so amazing (in my opinion perhaps the best note of any motor out there).
VW, to my knowledge never used a VR in TDI configuration, which is why I wonder what a VR TDI would sound like.
Here is a VR vid I can't get enough of this exhaust note I mentioned above. It is the 3.6 FSI VR6 in a VW Carrodo (engine swap from Vortex):
