Help! 1994 325ic air duct fell off

I was replacing my driver side fog lamp on my 1994 325ic, when I noticed a loose plastic component, which had been wedged in behind the bumper. It wasn't connected to anything, and it dropped off as I was removing the lamp bracket. I believe that it is a duct, narrow at one end and wider at the other. The wider end is angled, with openings for tabs. It has a part number which reads "51.71-8 156 251".

Can anyone tell me what to connect this to? Am I damaging anything by driving without it? Is there a diagram somewhere to show where and how it connects? I can't even find the part on any of the after-market sites.

Thanks in advance.

By the sounds of it, u knocked off the brake cooling duct.

If thats it, its sposed to sit:

One end attached to the end of the lower grille inside the base of ur bumper and the other end attached to the square cutout in your wheel arch liner... Wont cause any major problems if its just that thas fallen off...

See if this helps...

yah, I can't keep mine in because the underpanel screwholes are all sheered, so it's not snug enough and it will drag on the ground being pulled by the temp guage.
