Alfa 159 noise from engine
Hope you can help me out here.
I have a noise issue with my Alfa 159 1,9 Jdtm
Let me try to describe it to you:
The sound is never there when the engine is cold.
As the engine gets warmer the sound increases.
It is best describes as a kind of “singing”, that goes “whoop, whoop, whoop.
The “whoop, whoop” sound changes to a more constant tone when the speed increases.
It comes from the engine and the noise has a constant tone and doesn’t follow the rpms.
There is a tendency to an increase when I hit the gas.
There is a tendency to more of the noise when the car is in gear.
The noise is most present when driving around a parking lot or city traffic – 3. Gear app. 2000 rpms. But it is there no matter the speed or rpms.
Now I know that there are quite a lot of threads on “noise issues” in regards to the 159 but none of them seem to be the same as what I experience.
Thank you for your help.
Best regards, Christian. :-)
