Hey everyone. I've been having this recurring 2c32 code pop up since I had my DPs installed. When they were installed, the rear O2 sensors were switched. That was fixed and the car ran great for weeks. No dp fix was ever installed. Around Christmas time, I accelerated a little aggressive to avoid a rear end impact from a distracted driver. After I resumed my normal speed, the car began to stumble and turned on the check engine light. The following are the codes I pulled: 29cd, 29ce, 29cf, 2c32, and 2d5a. There was no room to pull over on the highway, so I ran a few logs.

Both show weird AFR patters. The first one has one bank running rich with the other running very lean, then they flip flop. The second log shows a wavy AFR pattern with bank 1 being the one that can't stay still. I eventually pulled over and cleared the codes. By then, the engine was running smooth again.


Fast forward to today and I still get the 2c32 code. On Saturday, while accelerating moderately, the car turned on the check engine gone light again and gave me the following codes: 2c32, 2c39, 2c3a. I cleared those codes and ran a log without resetting adaptations.

Tonight, I have the following codes: 2c2b and 2c32.


My 335is has the following mods: Wagner stage 2comp intercooler, VRSF dp, TFT inlets and chargepipe, TIAL BOV, and running stage 0 mhd while I do all of the preventative maintenance before getting a custom tune. I have done adaptation resets in the past and the 2c32 code keeps popping up. Before I start sinking money into parts that may or may not fix the issue, does anyone have an idea of what may be going on? Thanks in advance!
