I seach through the threads and I see lots of confusion about whether the transmission requires GL-4 or GL-5.

I see some saying it is GL-5 and others saying GL-4. Some people have used Red Line MTL/MT-90 (GL-4) and others LightWeight ShockProof (GL-5).

So is it GL-4 or GL-5 ???

...the GL-5 won't corrode brass....most do.

Yup...GL-4 in the gearbox & front diff, and GL-5 in the rear diff.

I could hear a sucking sound like vacuum leak while chaging oil this weekend - sounded like it was coming from near the BPV's. I might just be paranoid and it could just be the electronic butterfly valve operating normally, but it seemed much louder than I have ever noticed B4. Car seems to run fine and no MIL/CEL - but that doesn't mean anything...

Its GL2-GL5 compliant, so it was used for the gearbox/front diff and rear diff.

does anyone know what the G 052 911 A means?

is that just an Audi part # or do those mean anything in oil spec speak?

I removed the Y-Pipe to get access to it, but it was pretty easy. Did a pressure test afterwards, and no leaks.
