slostjoe, which codes are you getting. Is it just the 29e1 code or is there others?

I've gotten misfire codes and I assume it was just because of my NLS module. I've gotten a couple T map codes and a couple throttlebody codes nothing consistent.

I'm literally replacing everything on my car to trace down this issue.

I am also receiving the P29E1 and P2AAF. I am running Stage 2 cobb aggressive with the mix of E85 and 91 octane. I believe it's the fuel mixture. Also feeling loss of power, but maybe that's just me? Anyone have a clue?

So I been driving the car for about two weeks now. The code has not come back since the injectors replacement. So my problem seen to have been the injectors. I was getting the 29e1 code before the new injectors.
So anyone getting this code, here are some things to look for. Air getting in somehow, may need to smoke test, Fuel related (injectors, fuel pump, etc.), maybe carbon buildup (Unlikely the cause but a problem), verify o2 sensors are working (Most likely not the issue but check anyway). I was on a stock tune.
Hope this helps someone

I also had a persistent 29E1 code...I replaced all 3 Bank 2 injectors and the code has yet to return for 2 months.

What kind of issue with a fuel injector could cause this code but not result in some other perceivable issue like a misfire or the plug on that cylinder looking fouled?

This code keeps coming back but I haven't been able to track it down conclusively. Seems neither has anyone else... Anybody got any updates?

Got this code last week and after 1k miles its back. I just keep clearing it. Had a boost leak but fixed it and car runs and pulls fine.

Hi All,

I have a 2008 335xi that is keeps getting p0175 Rich Bank 1 & p29e1 Mix Control 2 codes together.

I'm not getting misfire codes.

Do mix control 2 and bank 1 cover the same cylinders? Could the o2 sensors be switched around?

What should I do first?

Car Background:
-idle isn't rough but not super smooth either
-New spark plugs about 10k miles ago
-Catless downpines
-Larger CXRacing intercooler
-93 octane E10 gasoline
-Cobb Stage2+FMIC Aggressive tune

I'm also gettin 29E1 and from my research the suggested causes (most suggested causes) are injectors, O2 sensors and/or LPFP.
