VW 505.00. ACEA B3/B4, API CF4 ,CG4 (pg 17-2)
However, the best is to read the owners manual specifically for the VW TDI 2001. Over the life of the MK IV there were various changes. The viscosities are all over tha map. There was even some controversy about whether to use synthetic vs conventional CF4 oils etc. Since this issue has had some time to resolve itself, I would recommend a 5w40 oil.
I personally use Delvac One 5w40, aka Mobil One Truck and SUV. on a 2003 Jetta TDI. I run 20,000 to 25,000 mile OCI's. If I didn't have a 500,000 to 1,000,000 mile horizon. Shell Rotella (among others) has its CF4 conventional and synthetic T for far cheaper than the EM products.
The 2001 TDI uses cartridge type oil filters.
