I have a 2014 F20 116i with 70k miles on the clock, I purchased it at 60k and got a stage 1 tune on it.
I've been noticing a rattle recently, Despite babying the car when cold and frequent oil top ups / changes.
Listen to the 1 minute mark in this video, Does this sound like wastegate rattle? Or could it be something else like the cam chain or, dare I say rod bearings? I'm not a mechanic so any advice would be hugely appreciated.
