M50 oil consumption

BMW will say that's normal. They only become concerned if its more than 1 litre/1000 miles. Check around the front timing cover and the valve cover for leaks. My M3 didn't leak any oil on the ground, but went through a quart every 1200-1500 miles. It had a leak on the timing cover that was very hard to see. If you are concerned about burning oil, have a leakdown test done. It will show if you are getting oil past the rings.

As Kyle mentions, that's not out of line. Our '91 525i M50 uses about the same at 150K - two dealers and two independents say it's ok. Most likely cause, if no smoke and no carbon buildup in tailpipe, is valve guides. Live with it - oil is cheap compared to any kind of work on the head. If you are still worried, have a compression and leak-down test done to eliminate valve seats and rings.

My gut instinct is that a liter (just under a quart) in 2000 miles is more than you want. Have you tried using heavier oil, 20w50 seems to be the oil that is called for in a moderate climate.
