Yellow sludge in oil cap dipstick m54
I did some research and people say its oil mixed with water/condensation. How dangerous is this and why did it occur. I replaced oil with full synthetic 5w:30 castrol titanium edge and bmw filter. The X is also garage kept. And drive around 30 miles a day. Sometimes more. But its a daily driver. What should i do? Obviously i will do an oil change.

You are not getting the engine hot enough, and keeping it at that temperature long enough, to burn off the condensation that occurs naturally.

If you are following BMW's oil change maintenance schedule of 15,000 miles between oil changes or waiting for the oil service light to come on before an oil change, that could be your problem. I change the oil on my X every 5,000 miles and don't see the yellow sludge that some people seems to have.
The maintenance schedule by BMW is to benefit BMW and not the owners. Less free oil changes means more money in BMW pockets. https://www.youtube.com/watch?v=BAzhwpc-0vU https://www.youtube.com/watch?v=XUdODglWxsI

Oil condensation. Short trips are the cause. Look for a longer route for your commute to run the engine to full operating temp to burn off the condensation. Take her on the freeway and use your Steptronic to run her in 3rd gear with high rpm ro burn those off.
Check your CCV.

Getting it hot doesn't get rid of the condensate paste so much as it stops more from forming. Get it hot and do a hot oil change.

super informative!!!! It seems that that yellow goop problem is applicable to many cars - my mom's Mercury Mistique must have died because of that, she was driving the car only a couple of miles a day for several years ( like 10-15 years)... the car's engine seized before hitting 89K miles.
