GL-5 in a VW transaxle is a no-no from what I understand, most of the EP
additives contain sulfur, this is why many people recommend going with a
synthetic GL-4. I know Redline is advertised as sulfur-free and yellow
metal synchronizer safe, that is why I tried it instead of the Swepco; I
haven't had a reason to switch since.

NB: this is based on my knowledge of VW 020/02A transaxles and may not
be applicable to the OP's Audi. FWIW Redline recommends MT-90 for OP's
app but I would get an opinion from someone who has actually used it in
that specific transaxle (search Audi-specific forums) before switching.
