    Loud whining noise on startup

    hi there,


    I got audu a4 quattro (petrol)

    On Cold start up, get really loud whining noise which goes away after about 1 min or so. Sound like aeroplane :-)

    Any idea on what could be problem.

    It seems to come from the left side of the car underneath, when facing car , but can't be 100% sure it's defo from there.

    I would be grateful for any diagnosis

    yeah i had that, still have actualy and many other people have had that rubbing noise from the front of the engine, i am pretty sure its because of the weather conditions. ive got a 2.0l sport petrol. i would want a definite answer aswell, but i dont think its anytthing major.

    I think I have this on my car also.

    It's like a whining noise. Almost like electricity.

    Probably SAI pump. Cheaper to remove than replace - only there for emissions on cold start

    Mine's a bit noisy too - will get round to getting it removed at some point and fit this:

    Perhaps worth arranging a group buy (if the numbers are worth it) with Forge???

    Hey,

    Thanks for the link and diagnosis. Sounded pretty scary when it first happened :-). Glad to hear it's not a big issue. I am having it serviced next week and will mention it to my mechanic. If the fix is as easy as suggested mate, then I iwll post response on cost and fitting etc. Thanks for everyones input.
