Which fender liner is it?

[jjcools]

On real oem there are two part numbers and they are different at bmwpartssource...

Is it 51718265468 or 51718193812??

I have a feeling this needs to be replaced on mine since there is a large hole in it and that corner had moisture in it at one point.

Now off to find the right mounting hardware...

You need the 51718265468. Which is for M-tech II bumper. The 51718193812 is for standard bumper.

Perfect, that is what I thought since it said aero package but wanted to make sure first. Thanks

Glad I could be a help.

I always verify the P/N on Realoem.
