VW R5 TDI with DPF: no bio-diesel, 507.00 oil (not 506.01).
"Diesel particulate filter warning lamp
When the warning lamp in the dash panel inser lights up (diagram of the warning light), you can support the self-cleaning action of the particulate filter by driving accordingly. Please refer to the Owner's manual, booklet>>Tips and Maintenance. The warning lamp will go out once the filter has been cleaned.
Do not use rape seed methyl ester fuel (Bio-diesel) in this vehicle!"
So it would appear VW Australia (at least) don't want you to use it (what a surprise).
I had a look at what I think was the DPF (a large cylinder approx 7" in diameter by 14" long immediately after the turbo). It has at least 2 sensors at the beginning (it's a bit hard to see behind the motor), and two at the end.
The DPF doesn't seem to reduce performance, in fact I think my T5 seems to go a little better (not run in yet) than the low mileage demo I test-drove last September.
The owner's manual specifically says I should use 507.00 oil NOT 506.01. 506.01 is still the recommended oil for the R5 motor without DPF. From searching FAQs on a Castrol web-site it seems the DPF requires a low Sulphur, Ash, Phosphorous, Sodium (low-SAPS) oil ie 507.00. I'm glad a people on this site like 507.00 as I was concerned anti-pollution concerns were going to force me to use an inferior grade of oil.
My Australian delivery MY2007 (new) Transporter T5 van (2.5L R5 TDI 128Kw motor) came with a DPF and had a little booklet attached to the keys (presumably so I couldn't deny getting it). It says (in many different languages):soberups said:Any speculation as to how well the '08 TDI's will tolerate biodiesel?
