In my experience, that’s the attitude of all Audi dealers I’ve ever dealt with.
What I do is get the part number and ring the VW Dealer, they’ve always been most helpful and many times Audi have told me something is totally unavailable... a call to VW usually results in “I’m sorry we don’t have one, I can get one for Monday”.
Just make sure the part you ask for is common to VW and not Audi specific.
