You should know that that keeps water from leaking down onto the injectors, causing them to fail. "reinforcing" isnt going to stop leaking.

Replacement parts purportedly do not have the same defect that leads to this early failure.

You might argue that this isnt a "trim piece" as defined in the CPO document..it is part of the "engine partition". It is not called 'trim'. It is not 'exterior' nor it is 'interior'. It is inside the engine compartment. Yes, I know what BMW says...but what is written in the CPO document has some interpretation room.

Troubling thing is that if the injectors fail due to water, that should not be covered by CPO if the cause was leaking trim....
