So far I know there are electrical and mechanical components of Vanos.
Electrical failure --> computer code will flash, SES light
Mechanical failure --> loss of power, bumpy idling / revving.

What is the worst case scenario that can happen when there is faulty Vanos. Will it cause bent engine valve? If so, how?

What is the protocol for BMW US to decide when to replace the Vanos? In Australia here, I was told that they can just recommend to replace the Vanos if it is noisy, because noisy Vanos means that there is no enough oil pressure in the unit.

Thanks

Nelson
