I assume you had new stuff put in when you had your timing belt changed.

Yes you have to drain the coolant to do the TB. "All rust"?? What do you mean? The color was red?

I would guess that it is brown from mixing green stuff with G12.

If the coolant looks murky brown, it is probable that someone used the wrong coolant for the car. Have it flushed and refilled with G12 (red from Audi dealer) mixed 50/50 with distilled water.

I wouldn't assume that the coolent was change when the TB was done, some shops would test the antifreeze and if still good they will put the old stuff back in, if you cann't be sure it was done i would do a flush.
