  • Loud humming from engine

    Could well be the boost control valve, located to the right of the bonnet catch.

    Get it done before it fails completely. You might find it impacts on mpg if you don't.

      Mine makes a noise if I slam the bonnet down what is the rough cost of the part. It is like a groaning noise



      Mine does this when I pop the bonnet after driving, but the engine is off so I wouldn't think it was the boost valve!

        I get the odd noise, does it sound a bit like an exhaust blow, humming sort of noise?

            Thanks to this site i had this issue on my Insignia and was able to diagnose it. All fixed this morning at dealer under warranty. Mechanic said they replace a lot of these due to the humming noise.
