Check your filter for tightness and if that doesn't fix, replace it and do an oil change because if the oil filter is overtightened it can damage the rubber seal.
my bmw has the same problem when i turn it on the oil leaks around the filter container but when it's warm the leaking disappears 540ibmw 1998 any help thanks ,,constelacion
You must replace the rubber seal in the cap every time you replace the filter. It will harden and flatten over time. No amount of tightening will fix this.

The rubber seal (large O-ring) is located just above the threads on the plastic cap, if it's not obvious (already flattened).
