You are absolutely wise in being cautious.  Use only Audi factory
mineral hydraulic oil part # G 002 000, or the equivalent Pentosin 7.1.
Do not use standard power steering fluid or ATF.  They will cause
deterioration to the seals in the hydraulic system ($$$).

No, such band aid measures don't work in the Audi hydraulic system.
Keep in mind that this system provides assist to both your steering and
brakes, and lives may be in jeopardy if it fails at an inopportune
moment...  Fix it the right way.
