I also hang out on a vw forum and over there they say I don't need to have oil that says 505.1 on it for my 02 Beetle and 03 Jetta, both with the same turbo diesel engine.
We filled up my sons Beetle with Rotella T-6 synthetic 5W-40. It says on the bottle:
Meets API Service CJ-4, CI-4 Plus, CI-4, CH-4, CG-4/SM
Meets the performance requirements of: ACEA E9, Caterpillar ECF-3, ECF-2, Cummins CES 20081, Mack EO-O Premium Plus, DDC 93K218, MB Approval 228.31, Volvo VDS-4, JASO DH-2, JASO MA
So is the Rotella T-6 okay for these engines?
