So, folks, about half a liter too much oil was put into my M57 E60 530d during a service, I noticed it after 1000 km. Do you think this noise is the turbo seal, or did it get louder because I installed a K&N drop-in filter? I couldn't tell them apart, and since it happened right around the filter change I can't be sure. What are your thoughts?
