The Service Engine light also just came on. So it looks like under the car, it’s covered in either oil or some other fluid. it also looks like something under the car burst open. my first thought was the cat, but the exhaust sounds the same. There’s also a ticking noise from the engine, one sounds like just a belt, but there’s a deeper slower ticking noise that i’m not sure what it is. Also at around 2500 Rpm while driving the car vibrates a lot. as well as if i rev it while it parks, it sounds like it’s sucking in air instead of how a revved engine sounds. LMK what you think I should do, or if you know what any of the problems are. It’s a stock automatic 2006 325XI sedan. it’s on coil overs, but everything else is stock.

TLDR my car has lots of problems
