I would put money on the fact that your intake-manifold needs to be removed and cleaned. (It is a KNOWN issue with running North-American crappy diesel in an EGR-equiped engine.)

Replying to: tdifun (Jul 06, 2009 8:50 am) A question for those far more experienced with diesels than myself, I can't recall what I've read/heard about max mileage and when you can expect to see it. If I'm not mistaken, is it around 40-50K?

Replying to: shrifty (Jul 07, 2009 4:51 pm)  app 410- 425 psi). This in in stark contrast to gasser engines 1,000 to 4,000 miles.

Does anyone know if there is permanent damage if you get low sulfur for fuel in the new TDI. I'm in New York, and they don't always label the pumps. (like whats 40 rating). I put a tank of LSD not ULSD. Car runs, no problem, but is there long term problems. Won't make this mistake again, found a station with proper labels, but a little more expensive.

LSD is still allowed to contain up to 500 ppm sulfur.

Replying to: moparbad (Jul 13, 2009 8:14 pm) When I bought my Passat TDI in 2005, I was able to find ARCO stations that only sold ULSD in CA. It ran great for the 8000 miles I kept it.

Replying to: gagrice (Jul 14, 2009 5:16 am) The Diesel Particulate Filter (DPF) What is it? I can not speak for the 2009, as I totally researched about (15-5 ppm) ULSD and the most likely damage would be to the (very expensive) DPF. On the road, I once put a B5 Chevron tank full, but I will stay with ULSD D2. Overall, it is way too new to tell and while there have been incidences of "mis fueling" (LSD) none have had LSD steady diets. Moreover, there have been no 2009 TDI LSD damage reports. Off topic, there has been RUG to PUG, D2 mixture damage reports.  So... do NOT try this at home !!!  The 2003 TDI was designed for ULSD (15-5 ppm) but (mine) was run most of its operating life on LSD ( 130 ppm CA & 500 ppm 49 state) (till Oct 2006 to present- ULSD) The EPA and CARBs even as they professed lesser emissions, controlled it to tactically FORCE.... MORE emissions.) 100,000 miles the TB/WP change was due so of course took the opportunity to look at and possibly CLEAN/change out the intake manifold and clean the EGR. The guru pronounced both good to go (to 200k or next 100k interval) The camshaft original tool markings was also GOOD news !!! For all intent and purposes I can tell no (SOTP) difference/s between LSD (both CA/49 state) and ULSD (15-5 ppm) Diesel ON !!

Replying to: ruking1 (Jul 14, 2009 6:38 am) So you have been burning LSD or worse for the past 100,000 miles and your engine is still squeeky clean? That seems to fly in the face of those with gunked up manifolds and frozen turbos. The common diagnosis has always been that the high sulfer fuel was the culprit. What's your system for avoiding that huge problem that some diesels have?
