Hi to all, I have a Octy II 2.0TDI Break form 2005 with longlife ( or variable ) service, and the motor oil i use is VW506.01, can someone tell me if the new VW507.00 it's OK, because it's hard to find the vw506.01 oil.Thanks

Yes, 507.00 replaces 506.01 for all VW TDIs (except for early 2.5 5cyl engines which should still use 506.01). 507.00 is suitable for non-DPF and DPF engines.
