I would run some high mileage oil to see if it slows the leaks some. I do that with my n62 545i and my VCG has slowed quite a bit.Barely noticeable now.
Or if you want to use your existing oil I would dump some atp stop leak or Liqui Moly oil saver. Power steering fluid is cheap and you can always top it off until you are in a position to do it yourself or pay.
