Rear differential fluid
What do they use in BMW rear differential fluid that makes it so expensive??? Unicorn tears?
Seriously though, I'm looking to do the rear diff fluid on my m240i. It's a non LSD. Can someone confirm this is the right rear diff fluid part number? BMW-83222295532
Certain sites have multiple genuine BMW rear diff fluid options so I just want to be sure since it's so expensive. 60 bucks a pop...
