I have zero knowledge/experience with this VW jetta DPF system, the glow plug light flashes , the DPF light is illuminated on the IPC, not flashing.
Multiple codes in the PCM and they will not clear either koeo or koer. The exaust @ the tail pipe felt like barely any flow. I removed the exhaust from the nox cat back and the flow seemed better, I visually inspected the electric throttle body type motor, it was in the open position. I removed the nox cat and visually inspected the inlet and outlet, no visible signs of a failure, does not mean it is not failed.

Possible DPF filter failure?

At this moment, I do not recall the dtc's in the pcm, vehicle has no power, MAF has 17 plus grams showing on data @ idle, I used the vantage pro and scoped the MAF and it does not respond on a wot, MAF voltage @ idle is around 1 volt, do not recall the exact number.

Any one have experience with VW DPF?

Thanks for any help/ input / direction!

Not much I can offer offhand as my diesel experience in limited to my RV (trial by fire over this past week - video coming) but it would definitely help to know what codes it has in it that will not clear. Then we can research them together.

VW diesels of this era had really serious problems with the DPF not regenerating. This is especially a problem on vehicles that only get urban/suburban use. With a diesel the airflow at idle is should higher than that on gasoline engine. I suspect regeneration will have to be forced or possibly the DPF removed and specialist cleaned off car. I have zero experience of doing this so it might be case of looking for a local DPF vleaning specialist or consulting VW expert.
