Hi everyone!
I have a problem, i've made a youtube video:
Alfa 159 2.4 high pich noise - YouTube
There is a high pich periodically noise at idle everytime, most noticable in the video from 12sec.

Swapped so far:
New high pressure pump
New intake manifold
Injectors reconditioned
New dmf, clutch (20k km)
New Steering pump
New Steering rack

If we take out the auxiliary belt the noise remains the same.
Please if you can identify the noise help.
