With BMW's there are common issues that happen every two years...Oil Filter stand Gasket...Valve cover gasket, and oil pan gasket. You need to understand that when oil touches rubber.. it destroys it over time. Also these cars have constant issues with oil vanos lines as well, and high pressure power steering hoses.
