My 2011 335xi keeps randomly throwing a 2c57 code at different rmps and times throughout each time I drive my car even after I clear it, I have replaced a few things which I would have thought would be related to the code suck as my charge pipe, boost converter, and my (MAP) or boost pressure sensor, and from what I can tell the car doesn’t have a boost leak. So what could my issue be?
