How hard is this to do? Will it throw sensors? What are my options to get rid of it?
Why will emissions go way up? It's burning the same amount of soot (just all the time, instead of infrequent bursts), and with a proper tune the fuel injectors wont be squirting fuel into the exhaust to burn off the soot. I'd say overall emissions will go down and DPF is just to make it so you don't see dirty black soot out of the exhaust.100% yes it'll throw error codes. I don't even think it would run well without it since the computer might send the car into limp mode if it doesn't get expected feedback from the various sensors. You have to have an engine tuner delete it in the software. Part of it is that the exhaust self clean cycle will be dumping fuel into the exhaust without the DPF in place.

FYI, the car's emissions will go way up and if you have state visual or smoke inspection you'll definitely fail.
You mentioned having the engine tuner remove the software for it. So after you do this can you remove the DPF? Also the whole reason I'm inquiring about this topic is because I plan on an ECU re-flash for the 140-170hp increase. A lot of the manufactures recommend a DPF delete. Is this a physical delete or software one?100% yes it'll throw error codes.

Because the DPF reduces particulate emissions, it doesn't just capture and burn them off in spurts. If VW could have passed emissions without fitting an expensive DPF they would have done so.Why will emissions go way up? It's burning the same amount of soot (just all the time, instead of infrequent bursts), and with a proper tune the fuel injectors wont be squirting fuel into the exhaust to burn off the soot.

Both physical and software. I don't know how the engine would run if you just cut the DPF out but I know it won't run right without the software accounting for it.Is this a physical delete or software one?
To clarify what Chitty responded with, the DPF stores soot permanently. It doesn't store it for a little while and then empty itself during a regen cycle.Why will emissions go way up?

Hmm thats something to think of since I'm sure an ECU re-flash will mean even more soot.Also, unless you also remove the catalytic converters downstream of the DPF, I suspect that they would become clogged with soot rather quickly.
Just to clarify something, the DPF is a filter. The other things are catalysts. The construction of each passageway on the DPF is a dead end, meaning that it really is a filter. The construction of each passageway on the other catalysts are tubes. Some stuff can pass through them but too much can clog them as well. They were surely designed to work with the DPF so I don't know how much it would take to clog them.Hmm thats something to think of since I'm sure an ECU re-flash will mean even more soot.
The end of life for the DPF is until it can no longer be cleaned, which is pretty much until the stainless steel hosing rusts out.Anyone have an estimated life-span for a DPF?
2 Things that confuse me about your explanation:This occurs primarily at higher engine load, such as in highway driving, when exhaust gas temperatures
range from 662°F to 932°F (350°C to 500°C).
So particulates are converted in CO2 not ash, and are then utilized further downstream in follow-on exhaust treatment and are utilized in the NOx catalytic converter.
