Engine/exhaust rattle when letting off??

[S3 Daniel]

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

Hi Daniel, most likely to be the heatshield that's vibrating

 

[S3 Daniel]

How can i stop it? its ****** annoying lol!

 

[Sandip]

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??

 

[S3 Daniel]

yeah it does when i rev it while stationery too, but only just started to do it last week whilst driving. its a hard noise to explain i'd like to get it sorted though.

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

well i did hit a rather deep pot hole the other day, only going at snails pace but it might of shifted something :S

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!

I had this, was the heat shield too. Pulled it off! Problem solved!

REALLY lol looks like im ripping it of then

 

[S3featesV9]

Yeah easy job lol. Mine was only held on by two heavily corroded bolts!

 

[Audiman99]

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?

use a circular badger saw with a 7" weenie hammer


beside been silly how about trying to heat it up with a blow torch or use a drill to get it off if you get what i mean

 

[Audiman99]

Don't own a blowtorch or decent drill my friend works at a garage ill pop down his and get it done, i've had enough getting under the car this week.

Thanks anyway
