Center differential oil for Audi A4 B6

[kevmor99]

I have some "Mobil 1 75w90 LS" (LS meaning it's okay for limited slip differentials I assume), will that work in a 2003 Audi A4 quattro center differential? I know the manual trans. models need GL-4 but since this is an auto (tiptronic), will this Mobil 1 GL-5 oil work or should I stick with GL-4? Does it need any other additives?

I think the factory used GL-4 in the center diff. but I'm not positive.

That will work well in your center differential.

Is it currently running?

Is that a Haldex coupling?
