Dear all,

Today I would like to ask for your help in a topic that I found very little discussion in the web.

My car has a noise when cold which is related to the vacuum pump (not the death rattle) and I want to know how to eliminate it.

It is exactly similar to the one in the video:
research "2007 R56 Mini Cooper S vacuum pump knock" on youtube
From the description of the video this guy eliminated the knocking by eliminating the pump and figured out that the noise was caused by some junction of the pump with the camshaft or something like that.

I reasearched BMW SIM110208 and they say it is not a problem but the noise is very annoying.

Does someone know how can I fix this? I already changed the vacuum pump for a new one and nothing changed...

Thank you very much,

Francisco
