Member Name: Andy_2009_JSW
Model Year: 2009
Model: Jetta Sportwagen
Tranny: DSG
Miles: 166500
Oil Ash Volume: 210 ml
Oil Type: Mobil-1 ESP 5w30
Avg MPG 35-ish
State: GA

Additional VCDS (version 16.8.2) data points:
4.2g Soot (calc)
0.0g Soot (meas)
1 Requested Regens
2.4l Fuel consumption since last regen
30km distance since last regen
48 time since last regen (minutes)

Remarks:
My P0401 (EGR insufficient flow) code/check-engine light has now been on constantly for probably the last 30K miles/18 months. Soot at tail pipe. Pretty certain DPF is cracked.

Back in late spring or so I had a month+ where car was doing extended 30+ minute regens multiple times per week (~250 miles avg weekly commute) -- this was quite concerning given dieselgate fiasco/uncertainty. I do NOT know if this is related, but I fixed a P2015 error code with the Diesel Geek motor stop insert early in the summer. For many months now regens have thankfully been much more normal; no more worryingly long ones, nor excessively frequent.

Any speculation if or how these could be related?

Wonder if that's accurate? Mostly because it's cracked. But then I've been dumping so much optilube it's almost pointless to stop for diesel....
And we now have an official winner, folks!

Towards the end ash level stopped increasing, and I was dumping in 16oz of super tech 2 stroke on every tank, and it would still always show zero for measured soot.

That thing was so ridiculously cracked. Such fragile components....

Otherwise I see DPF deletes in many people's future or dumping their CR VW (which is a shame b/c this car is awesome) for possibly Mazda Sky-D.

305,000 miles, zero regens, zero problems.
