So recently my x5 has been making a ticking noise from the engine. It started around a month ago, but it was much quieter back then. Now itÂ’s quite loud, and can even be heard from inside the cabin. Additionally, sometimes when pulling past 4000 rpm (in normal automatic mode), the engine will stop accelerating, and the turbos(?) will make a very loud unspooling sound (while my foot is still on the gas). After the engine returns to idle, it goes on like nothing ever happened. Has anyone had similar problems before? A video is included below just to show what itÂ’s like.
