X5d rhythmic pump sound at idle?

[stef]

I have the same issue, it seems to be in relation with the heating system (webasto).
My dealer changed a pump support last week, but it's still rumoring...

Inacceptable on a car around 70000€, even if the dealer make the best he can, it's still not working as it would on a one year and half old car. (they already changed the pano roof !!!, and some electronic stuff)

It's my 4th BMW, and maybe my last for a while because the quality is going really bad while the price raised nearly up to 20% (compared to my old e53 with nearly the same options). Even my dealer is really nice to me and do the best he can, i'm fedding up going to the garage...
