Does anyone know what screw/bolt type/part # and what the screw/bolt would attach to at the circled points?

The belly pan is bouncing around. I lifted my wagon looked through those holes and dont see anything to thread a screw/bolt to.

Also anyone know the part number for the screws for the oil drain hatch

Thanks

 

Have you checked on RealOEM?

 

yup
RealOEM.com BMW E61N 535xi Air duct

doesnt show the mounting point or which specific bolt

 

It's #31 on the diagram you posted
Let me find the part number for you.

 

Here we go:

Number 11
Part # 51717110995

Hope this is what you're looking for.

 

Is this for the belly pan or the oil cover?

Ill lift my wagon this weekend and try those screws again. I actually bought 5 of them from getbmwparts, but they didnt fit the pan.

The belly pan still has nothing behind it to bolt into those holes circled in red.

 

Ohh I'm sorry I misunderstood...
That two holes are empty in my car... There's nothing to tigh that two screws. I have 2008 535 xi...
Check your hoses sometimes the zip tie crack and the hoses can make noise.

 

It just occurred to me that those may be drain holes. If thats the case then my belly pan is installed incorrectly. It is tucked under the front bumper. Looks like ill yank it out and screw it into the front bumper

thanks
