Assistance with code

[Amsuarez86]

Hi All

I have an 09 M3 with no intake/exhaust modifications outside of a KN drop in filter.

I recently had a CEL appear and a notice that reads “Maintenance Required Soon” and “Increased Emissions”.


Upon evaluating the codes I received the following two codes

P2430 and P2432

bank 1.
Air system air flow/pressure sensor circuit

I was researching and found a post that references what I am experiencing

Drives fine, runs great, no noticeable issues.

Does anyone else have any specific experience with these codes?

Is it the secondary air pump? Or o2 sensors? Both?

Any guidance is appreciated.
