Thanks for watching! The great thing about n20 engine is that there is a lot of space in the engine compartment, so maintenance isn't too bad.

I have a white 2014 Z4 28i with this engine. So far timing is still good. BUT the car has always smelled like burning oil after I drive it. I took it in so many times. I replaced the oil filler cap, I had the valve cover gaskets replaced. Nothing fixed it. Eventually a GREAT mechanic found a teensy weensy little crack in the valve cover. It was so small it was almost undetectable. But when oil would leak, it would drip down onto the cat. So there's the burning oil. After I got the valve cover replaced it was gorgeous. I adore this car. But I wish I had gotten the blue like you have.

Interesting, thanks for posting 👍
