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.

Isn't there a history here
?
You are asking a question without an answer.
In the US, they replace the VANOS when the GT1 indicates a bad Vanos. A dealer can recommend anything they damn well please... this is especially true when WHO is paying can be a subject of disagreement.
Is yours noisy, is the valve bent, is there a few pages of 'story' behind this?
I won't post the links to your long stories of woe, but rather ask that you do the members here the courtesy of posing a question in context. Bring up the old threads, with all the background, and ask for help with the next step.....
Geez...
