Noticed I while ago the rear diff looked at bit to slimy on cover anyhow noticed today that it is in fact leaking and it appears to be coming from filler screw section but cant be sure as the screw sits at the bottom.

It is tight. It was serviced over 8 months ago so not sure maybe seal?

Any other ideas?

Cars under warranty so will get Subaru to have a look and sort but any info greatly received

Cheers
