Where does this plug into?

[X5Kev]

Self proclaimed newbie here with a 06 X5 3.0.

I just finished replacing the xenon lowbeams (very proud of myself!) but I can't figure out where this thing plugs into.

As far as I can tell, it only exists in the front-right side of the vehicle, so don't think it's anything related to headlights.

I struggled a bit replacing the xenons because I have headlamp washers but didn't want to take out the front bumper. I must have unplugged this while trying to gain more wiggle room, but I have no idea where this thing goes..

Any help would be much appreciated!

I think it's for the front PDC sensors, assuming you do not have PDC. It's been a long time since I wrote the instructions on that retrofit so forgive my less than definite answer.

secondary air, air mass meter sensor connector

thanks for the responses, guys, but now I'm really confused

If it's for the PDC sensor, then I don't need to worry about it because I don't have PDC. (right?)
But if it's the air mass meter sensor connector, then it sounds important.

Also, I started getting the "service engine soon" light, so i think something is definitely wrong.

Would someone be so kind and post a picture of this thing plugged in?

Again, it's in the front right side (passenger side) of the vehicle.

Thanks!

on your first picture, to the right side, this long corrogated tube the other end is the air filter for the secondary air system.

Thanks a ton!
