Black engin oil right after oil changing
I just had a engin oil change yesterday by BMW dealer on my Xdrive 20d, when I checked the oil this morning, it is black. I called the dealer, they said they did change the oil. They also said that it is normal with X1 diesel engines. What do you think?

Looks very normal. Unfortunately thats the way it goes with diesel engines. Only time ive ever had golden oil in a diesel engine is when i rebuilt a 3.0D engine had pretty much every drop was drained. 6 weeks later and its still a nice gold colour.

The dealer will use suction to remove less than 90% of the old oil instead of draining the oil from the bottom of the sump. There is a certain amount of old oil in the engine even after the oil change.
