I cant find leaks, and this is the first time in 5 years.

I've to just top-up or reflush the system?

mine was pretty low 2-3 months ago, I topped it off and hasnt dropped yet. Although it could just be an uber slow leak.

about 6 months ago, noticed it was low topped it off, looks to be exact same level since.

I haven't spent much time checking out my Audi PS setup, but when this happens in a front-engine P-car the missing fluid can usually found behind the outer seals of the PS rack. Wouldn't be surprised here if you've got a leaking PS rack and the fluid is being held in behind the outer seals.

We did our steering rack under warranty at 40k on our 00 30v. I've found the hose clamps on the lines off the p/s fluid expansion tank are a waste of time and should be replaced. They are a good source for leaks.

I've got some free time to have a look at the PS rack and it is clean.
