Engine Troubles: Keeping Your X3's Heart Beating

Alright, let's kick things off with the heart of your BMW X3 30i sDrive: the engine. This is where things can get a bit tricky, but don't worry, we'll break it down. One of the most common complaints revolves around the N20/N26 engine (depending on the model year) and the B46 engine which is more recent. These engines are known for their performance, but they can also develop some issues over time. A common problem that many owners encounter is the dreaded oil leaks.
