Hi
Ive been noticing a buzzing noise coming from the vacuum control selonoid mostly when the engine is hot.
I've allready changed the egr, egr cooler and the selonoid itself 2 years ago, with no success.
i still have power to the engine and the idleing is stable to.
Thanks for your help
Nathan

We don ot have a 2.2 turbo in US it is a 2.5 but from what you describe in ic I think is a vsv valve, try tapping it to see if noise quits if it does replace the solenoid. It may be partially opening or maybe a vacuum leak on line so check those as well if check engine light is on scan for codes and get back to us

I didnt try to tap it, but I removed the top connector on top of it. Then the buzzing noise had gone.
Next time it does the noise I give it a try and ill contact you, giving results.

I forgot to tell you
The selonoid we've mentioned earlier has been on the vehicle about 2 years !Because I had the same problem 2 years ago. Is it normal to become faulty again after a short time operating?
