Recently the "glowplug" error light came on while on the interstate. I pulled off at an exit, shut it down and got out the owners manual. Seems the glowplug light also means engine controller problems. Restart, and the light is off, for another 100 miles or so. Next the glowplug light and check engine light comes on, (steady). My shop is booked for a week (unusual) and I keep commuting. Next the DPF light comes on, and stays on. The car is in limp mode, way down on power. My shop diagnoses EGT sensor, plus DPF, and says he thinks those are covered under extended warranty, so take it to the VW dealer, and I do.
VW agrees on all counts, orders parts and installs them; no warning lights and power restored.
I asked what the cost would be w/o warranty, answer $2200!! I asked my shop what they would charge to replace DPF. Answer, "we have not done that yet, market dried up due to dieselgate".
VW service writer suggests that the DPF clogs due to poor fuel quality, while, an oil knowledgeable guy (tooslick) has told me that "low metallic ash" oils are needed in TDIs as that's what fills the DPF.
Before all the trouble, the Polar-FIS canbus gadget indicated DPF load of 60 perhaps 3-6 months ago, and when the error lights came on, was at 69. Now reset to zero load.
Q1. What fills the DPF on our TDIs? Fuel or oil combustion products?
Q2. Is 85K miles about what one should expect for DPF life?
Q3. What can the driver do to minimize DPF filling? Italian tuneup or?
Q4. Whats a fair price for DPF replacement?
Q5. Does any company refurbish our TDI DPF?
