    Over the past week I have noticed what I would describe as a low grumbling noise at very low revs under acceleration, this does seem to go as the car warms up and doesn't happen every time.

    Any ideas what the noise may be?, it is only a recent thing I didn't notice at all through the winter.

    Thanks

    My turbo makes a rumbling kinda noise. Similar to you I notice it at at low revs. It's going back to Audi to have it changed.

    The only other thing I had was my clutch but you'd notice this as the car would judder as you pulled away. Mind you I only have the 2.0 170 TDI engine.
