    Hi,

    had a scout through the posts but not found anything that matches the issue;-

    210 S3, it makes a strange ticking sound, almost like a leaf stuck in a bike wheel, this only happens when the engine is under load, sound like its coming from underneath the drivers side? It makes the same when driving in straight line.

    I cant replicate it when the car is parked and running, and for some bizzare reason it never makes the sound driving into wo*k, but always on the way home???

    Any ideas would be most appreaciated.

    A stone caught in the tyre tread? Happens quite a few times with my S3.

    Only other ticking sound was from the passenger side that I got this morning when I ran out of Power Steering fluid.

    Do you have split rims on or stock style one piece wheels?

    I had a weird noise like a stone in the tyre tread, but only when warm...turned out my OEM split rims were creaking as one of the bolts had stripped its thread and gone loose!

    I have the std 17" Avus wheels as OE fit, were would I look for this? The sound is a mechanical clicking, with a tiney element to it.

    I had this.... I'd got a nail stuck in my tyre..... sounded like a ticking noise...had me worried for a week. Drove round with the window down listening too it wondering what the hell it was.

    turn your aircon on and off and listen to see if the noise changes

    I generally drive to wo*k with the a/c on then home without it, I assume you reckon the a/c system is causing the noise, if so surely it would only make a noise when running??

    sorry.. i re-read your post, you cant replicate it when sitting idling... I was getting a similar noise before, and it went away when i switched the aircon off... in the end i got it refilled and fixed the noise.. so perhaps its not the same issue :)

    it might also be your charcoal filter doing it. Open your engine bay and it's on the left (on an A3)

    you should hear it....i guess.
