07 335i - Knock Sensor Fault
I have a 2007 335i with 90k. It started going into limp mode with a knock sensor code. This started out being pretty sporadic (once every few days) It even went 10 days without a limp mode after I replaced the spark plugs. Then it got much worse, going into limp almost on every drive.
So I pulled the intake and replaced the knock sensors. It drove great for 3 days then went into limp mode again with the same knock sensor code. I'm looking for suggestions on where to check for this intermittent issue. Thanks in advance. |

My issue was resolved by having the DME updated with the latest release. No problems with JB4 any longer....looks like I replaced the knock sensors for no reason. Oh well, at least I learned how easy it is to get the intake off.

knock sensor question
I have a 2012 335i and suddenly have to have the engine serviced soon. I took it to a BMW shop last week, which didn't detect any problems. I connected my OBD2 this week, and a knock sensor failure came up. The car runs perfectly with no issues. Do you have any ideas? I'm planning to replace the sensor this weekend.
