Check your tubes!
Could this be a problem? I’m thinking…yep lol
These are from my 2016 X5 50i. To be fair the passenger side wasn’t totally separated, it was just cracked. But I broke it apart while checking how big the crack was. The driver side was 100% separated. I wouldn’t have even known unless I occasionally pulled codes (was getting a bank 2 lean code on occasion) as there was never a check engine light. Who knows how long I’ve been driving with it letting in unmetered and unFILTERED air going into the engine 🤦‍♂️
Lesson learned…change those important plastic pieces, my friends! Both tubes were a total of $122 shipped from FCP Euro and carry a lifetime warranty now. Took just over an hour to swap out, and that included figuring out how to take stuff apart to gain access plus a 10 minute call from my mom. 😂
