Wrong gear oil destroys newer BMW front diff

Also I think this guy set out to say "Look how great we are," but to me he's now embarrassing himself with incorrect conclusions.

Doing the right thing for the wrong reasons makes me question if they later do the wrong thing for wrong reasons.

Plot twist, the car was actually owned by a member of his family.

'tis possible

One possibility for excessive gear wear is that the unusual angular-contact ball-bearing pair used on the diff carrier lost preload and disturbed the correct hypoid contact area. It wouldn't take much clearance for this to happen.

I'm thinking the drain plug wasn't tight and it fell out in the week following the change....

Most modern bimmer diffs don't have a drain plug. The old fluid must be sucked out.

That's legit awesome on the shop to not only own up to it but also produce a video showing their mistake.

Option A: Suck it up, take it like a man.

Option B: Make a video about how much of a man you are and how manly you're taking it. Find the most outlandish reason why a BMWs front differential grenades in a day other than It's a front differential on a BMW. Have the video pay for itself. Rake good will and money by monetizing the fact that you're a stand up person not interested in money.

BMW front diffs take gear oil. If it was the transfer case - that one we can discuss, it's unicorn milk boiled on a solar stove at full moon.
