Avg MPG 35-ish

Additional VCDS (version 15.7.3) data points:
14.4g Soot (calc)
1.8g Soot (meas)
4 Requested Regens
21.3l Fuel consumption since last regen
340km distance since last regen
372time since last regen (minutes)

Remarks:
My P0401 (EGR insufficient flow) code/check-engine light has been on constantly for probably the last 20K miles/12 months. Soot at tail pipe. Pretty certain DPF is cracked. The emissions/dieselgate fiasco has put any alternative remedies for this on hold...

Arrow If you take the buyback, you can't strip it

Quote:
Data should be current as of June 30 2016. The value under buyback is how much you can sell your entire car back to VW for. The value under modification is how much you would get if you keep your car and have VW fix it
Might be able to down grade the tires etc.

That's an intense list. What're you going to do? part it out? or do you dare tackle all those problems?

Interesting update.

OEM software....

Unplugging the maf it goes from 36mpg to low 50s. And the trip odometer and pencil math shows it....

Once I get a dpf light I plug back and let burn, but immediately unplug and continue. I'm making 650 miles a tank instead of 530...

Seriously, ***?

***????

Jason- that is really interesting. Are you physically disconnecting it or are you turning it off using VAGCOM? I no longer have a DPF, so I wonder what issues, if any, I would have running without the MAF?

If you can turn it off via vcds show me. But I'm unplugging it for my experiments.

If no dpf it's OK to unplug. When it's unplugged the egr and exhaust flap default to open, and kills exhaust Temps to passively burn soot.

Turbo spool is a little weird and I don't think it has its full grunt when unplugged, but it's plenty to go down the road and climb Hills in high gear.

Greetings fellow diesel-goers.

My participation in this thread has been dwindling down for months now (obviously). Wondering if any of you would like to keep it going and keep it updated? I'm willing to pass on the Excel file(s) that I have kept. My interest in this has faded away. Family, work, kids, etc. keeps me quite busy and to be honest, I don't give 2-sheetz anymore. I've been DPF free for two years now- almost 44K miles ago. Now 186K. Car is still running like a champ. My goal was to keep this car and give it to one of my kids for a high school/college car. Now the goal is to keep it running until I can sell it back to VW. Then it's time to move on.

If there are any takers who want to continue or maintain this info, send me an email or PM. Otherwise I guess people can continue to post their DPF data.
Cheers!
