I wouldn't worry about it. As long it's installed properly it will be fine. I'm guess the factory nicked the seal when they installed the axles. No way for us to know.

Ok....Update.
So after the initial repair, which was replacing the axel seal, (dealership replaced both sides) all was good.....for a little while. Then I notice the drip again on the garage floor. Climb underneath to find a drop on the black tube that looks like a vent. Brought it in to dealership. Tech went back and forth with BMW on a couple tasks. In the end, BMW recommended a new rear diff. 3 to 4 weeks from Germany. Rear diff alone is $5700. Thank goodness for a warranty. It seems like they are being proactive. |

I personally wouldn’t accept any leakage even if it apparently stopped. What is to say it won’t leak again? It doesn’t matter what caused it, it’s leaking and it shouldn’t. If I were you, I would tell them to fix it.

To be honest, this doesn't seem like a good explanation, unless they looked at it. Why should it leak? Anyway, now that it isn't leaking, if you see it again you know it wasn't due to overfilling...

A leak is not normal. Like others have mentioned, I would push back on the service advisor. What model and trim line do you have? Also, just out of curiosity, do you notice it after any Launch controls? That is when I noticed mine. |

Well ok then. That explains it and yeah, a leak is expected considering the tune and abuse. The context of your original post was lacking.

Does the dealership know about Tune? They did have to hook my car up to the computer and did their digging. I respected but pushed my X3M and F15 50i hard. I tracked and launched both, a lot. Never had a diff issue or leak. What tune are you running? What level of torque are you pushing? |
