Just did a downpipe install on my 2011 N55 and the car runs great, but the SES light came on. Read the codes and the car is throwing code 2D0D: o2 heating before catalyst, line disconnection.

Anyone have experience with this? Thinking I screwed up an o2 sensor with the install.

Very possible. Did you have to apply heat to remove the O2 sensor from your old downpipe? My rear o2 was damaged from the heat applied to remove it. I had a code that went away after I replaced it.

No, did not use heat—rear o2 was stuck for good so I replaced with a Bosch universal one. I'm thinking it's possible I might've messed up the wiring for the front one while removing it. Ordered a replacement and going to update thread when I install.
