2010 135i running rich p0175

Crose87 · 10-16-2015, 07:45 PM

I'm sure this question has been asked before but I can't seem to find a consistent. The service engine light on my 2010 135i just came on and the OBD II code P0175 came up. Does anyone know what might cause this and how I can fix it?
Thanks!

Although this is a 1M forum, I'll try to help out but I need to know if and how your car is modified and if there were any other codes.

Also, how many miles and when were the pre-cat O2 sensors last replaced? If it's entirely stock and the 02 sensors are old, I'd consider replacing them.
