N55 Catless DP CEL Fix

Quote:
I was hoping some of you could help clear up some confusion for me, I've been getting varied answers from searching google/forums and talking to people personally.

Is there a working DP CEL fix for N55? And is there one that'll completely remove the code so it's undetectable during emissions?

I was hoping to get a Cobb AP and have that fix everything, but I'm told there isn't a Stage 2 for N55 yet.

Thanks everyone, I appreciate your help.
Current discoveries for N55 Catless DP
  1. JB4 Auto Clear WILL NOT prep readiness for emissions
  2. Wrapping the O2 (for cat diagnostics) around the DP will make you throw a code for too much O2
  3. Companies have so far abandoned further production on a fix like the BMS one for N54 engines because the N55 DME isn't as easy to fool
  4. High flow cats still throw the SES
  5. Cobb AP Stage 2 will not prep readiness but will rid the SES light

TL;DR: there is no fix besides switching back to stock
