X5M clicking sound from engine

[xsix]

I think we are talking about two different sounds here.
Im talking about the lower tone clap that does not change pitch or frequency when revving the engine. It is not valves, lifters or injectors. You can hear it very well in the video below behind the ticking sound. What can it be?

If not check out the purge valve for the charcoal canister. Unplug it see what happens. I had a similar problem. I let the dealer fix it for $400 but in retrospect it's easy to get at and only a $85 part.

edit: the dropbox link and the youtube, sound normalish. I have a 50i not M but it's pretty similar.

Thanks!
I will try it out.
Where is it located?

You can search realoem.com but mine (N63) was on the drivers side of the front of the engine. Sort of underneath the inter cooler fluid reservoir.

I have same ticking sound but with annoying sound it's more like whisteling, and the sound speeds with accelerating
