E90 xdrive oil pan o-ring passenger side

johnyellow · 03-21-2024, 08:27 PM

Hi guys!
I need some help. I dropped the oil pan on my 2011 e90 xdrive. Besides a leaking oil pan gasket, I had a leak from the oil ring that goes behind the plate in the picture I am attaching. This is on the passenger side and it is where the support bracket with the bearing for the passenger axle. When looking from underneath, you can see the bead of silicone/rtv from the factory. I thought it was held together by rtv only but there was that goes around the perimeter and also circles around the two middle blots.
I have been searching high and low but cannot find a part number for that o-ring.
Has anyone replaced said o-ring?
Thanks!

Shaft Seal 33107505601 2x
O-ring 31511213527 2x
Snap Ring 33131214961 2x

I would advise to get genuine bmw on these, I've seen people have issues with coreteco. Although I did install a corteco shaft seal on my car for CV axle replacement 2 years ago, no issues.

Big props doing opg on xdrive. Have to do it myself some day.
