    and now...Clicking / Knocking

    Hi all,
    My first post after lots of lurking; great forum.
    I hope some of you can shed some light on the following.

    S3 2000 (210bhp)
    No modifications apart from the 18" Alloys.
    Car is relativley new to me.

    So, I had the lateral acceleration sensor throw up an error on VAG COM, got a new sensor, cleared the fault - all going well. Started planning my next maintenance tasks.

    Around the same time I became aware of a click/knock while pulling out of the drive in the morning. Noticable at low revs just as I'm letting out the clutch, especially on a slight hill. The rate of the sound increased with the engine revs / or the wheel revolutions.

    A few days later the oil light popped on on the way to work, I should have check earlier but there we go... So I filled it up and almost immediately I noticed this noise was less common.

    Been a couple of days now and the noise is intermittent. I have heard it while stationary with the drivers door open gently reving the engine, at other times doing the same thing I can't hear it. The garage I bought it from are off ordering ARB bushes - i suspect they are deaf, but that's another story.

    Any thoughts?

    Cheers

    Finally got the car back today, with a new block and some other refinements.
    Turns out the "knocking" was a shattered middle piston ring on the 3rd cylinder; I now have it in a plastic bag to remind me of the pain. The conrod on the same cylinder was also slightly bent; as a result of the piston ring there was oil residue over the valves and manifold port.

    Contemplated replacing all the internals - opted for the new block from Audi with 12 months warranty.

    How much was the block from Audi if you dont mind me asking?

    Did it fail big time or did you have it stripped and inspected?
