I recently purchased a 2011 X5 5.0 with approx. 40,000 miles on it. I had the oil changed by my dealer at 40,280 miles ( Sept. 14, 2013). The vacuum pump was also found to be leaking oil and that was replaced. 2,000 miles later, my oil level is showing at about 1/4 above the minimum. My Service Advisor is saying that that is normal and I should expect to add oil. It does not sound normal to me. Any ideas / comments? I have a great independent mechanic that I could take it to, but I hate to do that while I am still under warranty. I also hate to let this go as I only have another 7,000 miles until I lose my warranty. Thought?
