Which Oil Spec to Use in a VW PD or DPF Diesel?

It's time to service my VW Golf PD Diesel so I need to look around for suitable oil for the oil change. I found this really useful guide to checking which oil specification is suitable for different Volkswagen diesel cars with PD or DPF engines.

On checking the guide the oil for my PD 150 diesel needs to meet VW spec 505.01, 506.01 or 507.00 depending on the service schedule. 506.01 is for long life servicing but won't harm the engine if use for time and distance service which is what I do as I service the car every 10,000 miles.
