Check Engine light and codes - BMW Forum

Hey all. I recently got a CEL and the following codes:

11: Camshaft Sensor
E9: Automatic Start Output
F6: Secondary Air System Flow Too Low

I know what 11 and F6 are, but I'm having some issues figuring out what E9 is. Can anyone clue me in on this?

Most likely just the Camshaft Sensor, causing the E9 code........

Does the car start? Also check the secondary pump & make sure it's operating.......

Car starts and runs. I cleared the codes to see which code is real and which code may have just been one of those blips cars gets. It's been about 2 days and no code has come back yet.

Alrighty, I cleared the codes and 11 and E9 came back last night. Looks like it's time to replace the camshaft sensor. I heard it's not hard, and thankfully I have the manual from Bentley. Hopefully I won't get the F6 one back. Thanks for your help!!

Alright, due to some stupidity on my part, I looked at the wrong table.

I've got two errors.

Cat low efficiency cylinders 1-3 and Secondary Air System Flow Too Low Cylinders 4-6.

It could be the Cat on it's way out, but I would try and replace the pre-cat O2 sensors first!

That's what I was thinking. I'm going to try to replace the secondary air injection system's check valve first since I'm getting an error related to banks 1-3 and 4-6. Near 100k miles, I'm sure the O2 sensors need replaced anyway.
