error codes?

E90M3velocity · 02-02-2020, 05:17 PM

Started the car and went into limp mode right away without any rough idle. Pulled the codes and I got these-
2AF9 - https://www.m3post.com/forums/showpo...8&postcount=85
2AFB - all I could find on this one is from the 335i forums showing it as the nox sensor
2B20 - https://www.m3post.com/forums/showpo...5&postcount=86
CDC0 - https://www.m3post.com/forums/showpo...1&postcount=14
2B57 - https://www.m3post.com/forums/showpo...43&postcount=4

Both TA's, ICV and FBV were all replaced and the coolant system was refreshed recently. Not sure where or what I should be looking based on these codes, anyone have a better idea on whats wrong with my car now?

Anyone? I can clear it and drive it fine for a bit until it goes into reduced power and limp mode. The latest when I pulled the codes were-
2B16
CDC0
2B57
2B15
CD93

The TA's were replaced by MPower Motorsports and I'm wondering if it the throttle position sensors... have anyone replaced those sensors yet?

I've switched the TA's 1 and 2 around and when it went into limp mode in a couple of minutes after I started it back up to run an errand, codes CDBF, 2B16 and CD93 were pulled. I cleared it and it went into limp mode again, codes 2B15, CDBF and 2B16 were pulled. From what I remember this is only happening in city driving, but it might be coincidence since I did hit stop and go traffic.
