Hi Guys

Wonder if you guys can help?

I have a Z4 3.0 with the M54B30 engine. Car runs perfectly and smoothly.

Looked under the cap the other day and noticed there is like a brownish substance under the oil cap. Looks pretty dry, not really moist at all.

Seen a few guys have said that it sometimes occurs from short trips etc
