Omf - dpf regen light on - B7 Passat TDI

[h100vw]

I don't think it's such a big issue myself. One might say 'that's easy to say as you can "sort the DPF" ' However, I have seen blocked ones on MK5s at 105K and others no where near half full at 150K. Even a MK6 that had 160K up that was blocked. VW blamed his driving style, Eumundi to Cooper Plains daily on the Highway. What you would expect to be the best place for it???

I would have no problems running one personally. I would however be monitoring the DPF regularly, you can check the state of it (well what the ECU thinks it is anyway) with VCDS.

I'd do the pressure sensor at the first sign of trouble and calibrate it. Then drive it.

hmmm, I'm thinking the moral of the story is don't buy a TDI!

With all the recommended driving techniques that are talked about, I'm hardly game to drive the bloody thing now for fear of clogging the damn filter! I like to use the go fast pedal quite often, but at 16000k's obviously I'm going to be suffering the dreaded DPF issue at some point very soon by all reckoning

The dpf critical soot accumulation levels should be checked by the dealer as per service schedule, i know that for a fact on audis anyway. Clip don't be scared off by them, the diesels are great i've seen them do 1000+ ks to a tank. From my understanding unless its changed, yellow dpf is a regeneration (burning of soot accumulation in dpf) capable of being performed by the customer, red dpf warning light indicates that the dpf is saturated and requires immediate forced regeneration which can only be ran using manufacturer diagnostic equipment. Essentially the ecu stalls up the car between 1500-2000rpms and gets the dpf red hot in an attempt to burn of soot. The g450 exhaust gas pressure sensor is used to help calculate critical soot accumulation in the dpf.
