2012 335i over 60,000 miles at the time of this post. (99,500 km to be exact).
Replaced the spark plugs myself when i changed the oil and filter for the first time since the warrantee expired.
Oil has been leaking recently at the back of the engine so i decided to replace the valve cover gasket. Did it myself a few weeks ago, and guess what? No more leaks once it cured
