Pretty much any modern engine has plastic timing chain guides and has had them for decades. It’s meant to be replaced when the chains are replaced. But if they aren’t being serviced like they should then guess what? It’s not just a BMW thing. Tight tolerances isn’t an issue on BMW engines, it’s an issue on VAG engines, especially the 2TFSI models from 2008-2013, specifically the tight piston to bore clearance on those engines.
And I deal with independent mechanics all the time. Some are good and some aren’t. Just like plumbers, electricians, garden technicians and the person that made your Kentucky Rounder.
BMW’s decision to stick to Castrol and long service intervals wasn’t a great idea. Nor was it a great idea for any and all other manufacturers who went the same route. Don’t get me wrong, there are many dumb design choices they’ve made, like the bearing design on the S54, S65 and S85 engines. But they’re not the only manufacturer guilty of this
