Should I be worried if they put 83 22 1 467 993 oil in the diff? I know that the only difference is that it doesn't have the +FM in it compared to the 583.

Also are we sure that it came w/o the +FM in it from the factory (I know Dackelone is already thought to have confirmed this)? I have noticed diff noise, which I don't mind, I just want to make sure that I didn't start with +FM and now I don't have it, because that would be bad.

Supposedly my dealer has the trans fluid which will get switched out tomorrow. We'll see what they say though.
How did your service go?
