I've got the same issues. But know one seems to know anything. I'm heading to the dealer Tuesday. If they can figure it I'll let you know.

Did anyone get a resolution on the knock sensor issue? I am experiencing the same codes right now.

YoungBlood · 08-03-2016, 02:49 PM

The 3100 is cut boost due to the other code

Julian2485 · 10-11-2017, 01:33 PM

Has anyone found a fix for this code

Julian2485 · 05-29-2018, 11:23 PM

Anyone ?

Bimmer_Engineer · 06-29-2018, 11:42 AM

Okay...so I got these codes this morning. Was driving my kids to camp and while stopped at light the dash flashed "Engine Malfunction Detected - Reduced Power"

I shut the car down and when I restarted the warning was gone. I scanned for codes and got these. I've plugged the exhaust flap back in...any insight?

I literally just swapped out the knock sensor myself and all is good so far.

How long did that take?

NVM...I read the description the pelican website. It looks like you have to take off the intake manifold. Sounds like a good time to do a walnut blast too...

Took about maybe 45 minutes had to take off intake intake mani and sensor is sitting right there on the block
