DPF Delete questions

[boom]

So I have a persistent CEL: 004804 DDE Reducing agent pressure buildup, plausibility.

Found this but no resolution.

I've already replaced a DEF tank and am tired of spending money to fix a system that is unnecessary, problematic, and costly to repair. I have read a bunch of threads about tuning and deleting the SCR and EGR systems and looking for information on a fully sorted setup. I'm prepared to by the downpipe and tune, and I'm looking for the complete package that will allow the OBDII diesel emissions check pass.

Thanks in advance.

I used BPC on my Xd- bimmerperformancecenter.com in NC. They are great to deal with.
Advisor is Randall Tuner is Bob

I used JR Auto Performance and bohldieselperformance for my 335d. Good option as well

More info on the M57 forums here

If you wanna save some money you can always gut your DPF and SCR, I gutted both of them myself, cost 200$ for the welding and the rest labour for installation

Intricate mindz in langley, really good mechanic , labour rates are good plus work is top notch and really down to earth guys, they installed my DP about a year ago and took them roughly 4 hours which wasn't bad. Going to be getting my gutted dpf put on this Wednesday

What about sound, is it any louder inside the car? I definitely dont want any drone.

You get a nice little whistle, it's enoogh for people to notice but not enough for inside the cabin , WOT sounds pretty good and no drone in city or even highway. I might just end up deleting the muffler which will sound amazing

Hey man - i'm looking into removing DPF and all the other emission crap from my X5 diesel. Since you are local - would you mind sharing some info on what you have done to yours and who coded it all out, as well as anything to avoid?

Thanks!
