I am looking at this 07 pre-LCI e93 335i at the dealership and possibly going to take it home around next week, and this cable bothers me a lot.
The price seems to be a good price for me regarding that it has 81k miles and I talked it down to $8k including fees.
This cable is just dangling in the engine bay, and I am hoping that it is nothing serious.
I had searched many times looking at cable diagrams and harness diagrams, and I had not seen any cable that looks like it.
Any mods that I know of about this car in terms of engine is BMW power kit.
I had seen a couple other 335i either that my friend owns or family friend owns and this specific used car for sale has this cable/harness.

It's for the sensor that goes on the cawl. Look at the mounting tab on the cawl with round opening whee the red positive post is.

I appreciate a lot for your reply.
When I visit the dealership in a few days, I will definitely check on it and possibly update on what happens!
Again, Thanks

It is just not clipped into it's spot as fuer noted. If you look at your photo and the red battery post, if you look to the left you'll see a circular tab on the cowl with a hole in it. It simply goes right there.

Looks like they missed a spot when they were cleaning the engine bay...right behind the oil filler cap...

it's called the AUC. it measures outdoor air quality and will automatically put your cabin HVAC in recirc mode to avoid a breathing a pocket of bad air.

I've never seen it actually trigger in my car. I don't know how to effectively test it. Maybe commission someone to coalroll me, while it intentionally follow close? Or I could just drive to LA.
