Hello all, I've been having a weird overheating issue on my 2011 X5 35i 65k miles. Took it to the dealer Nd they told me that it was due to a loose hose they tighten it and added about half a quart of coolant that was gone. On the way home I started hearing the fan on and off then when got off highway about 10 minutes later fan when on full blast and the drive moderately warning came on.
They told me the water pump is fine and until there is a code is hard to diagnose. But today I checked the oil cap because right before the over heating issue started I noticed that my oil level when up without adding oil it when from 1/3 quart up to full green. I found a milky white residue on it an right on the inside of the oil intake. Here are some pics.
Engine starts fine, no vibrations, no white smoke.
Some guidance would be gladly welcomed.
