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.

VW Passat B6 Engine Undertray Removal (2005-2010) for Access to Oil Sump drain plug

To change the oil on a VW Passat B6 (2005 - 2010) you need to be able to remove the engine undertray and know the location of the retaining screws that hold the plastic tray in place.

You'll need Torx T20 and T45 screw bits to be able to remove the retaining screws that hold the tray to the car. There are 7 T20 torx screws at the front and side of the tray and 3 T45 screws at the rear. Access is quite hard with the car on the ground so it is much easier if you can jack one side of the car and support it with an axle stand.
