I have talked to various bmw mechanics and some of they say that (some) Vanos rattle is normal. That a lot of Vanos rattle is Not normal. Want to now what is the general opinion on this issue, my M5 only makes some Vanos rattle when cold, but when its warm the noise almost dissapears. Could there be a problem?
