    Engine/exhaust rattle when letting off??

    Hi Guys,

    My first issue since buying my s3 a few weeks ago, last week my car started to make a rattling noise towards the front of the car when i let off from accelerating. could this be a problem with the exhaust downpipe or something like that? i have no idea about mechanics etc so if someone can point me in the right direction that'll be great.

    Cheers

    lol you'll have to go on a mad hunt to find what part is vibrating, does it do it if you rev it whilst stationary??

    i had this stupid rattle a couple of weeks ago, i thought it was my heat shield but it turned out my exhaust had moved over a little so it was vibrating off the underneath of the car pretty weird i have no idea how it had moved

    Did you ever sort the problem? I've just discovered I have the same problem but am worried it may be the cat.

    I had it too, its was the heat shield after I clobbered it. I just pulled it off as it only had one spot weld holding it back on. I think most of them had corroded anyway and hitting it on something was the final nail in the coffin for it.

    Its only a shield on the underside of it to stop you setting fire to long grass when you park up so nothing major!

    Typical car, couldn't get it off, 2 front bolts come off fairly easy but it seems the 2 rear and middle have fallen off and corroded to the heat shield and wont budge, was hitting with a mallet and tried chipping away at the corroded metal but no luck. Any tips?
