Good evening,

2011 335i e92

I have been running into this issue for months now and have not been able to diagnose it, I have searched everywhere and it seems as if i’m the only person in the world who’s having this 304D code. New knock sensors and wiring has been inspected all the way down to the DME and is fine. cannot for the life of me figure out what is causing this. If code is cleared it returns as soon and i go over 2100 rpm’s. engine is running fine and does not have actual knock.

any help is appreciated, Thank you
