EP3 Metal vibration/drone noise at 3.5k revs

Hi everyone,

New to this forum as I have an issue with my ep3 that I can’t really find any info on. I have noticed a noise that has gotten louder over time. At around 3k-3.5k revs I can hear a metallic vibrating or drone noise coming from underneath the rear drivers side of the car from what I can tell. It stops completely at 4k. This is under accel and decel. And gets louder the more the car warms up after starting it from cold, it’s barely there for the first few mins of driving.

Could this be as simple as a heat shield vibrating against the exhaust possibly or does anyone have any ideas? I don’t exactly have much mechanical knowledge to think of what else it could be so any advice or help would be greatly appreciated,

Cheers guys
 
Yeah as you said check the heat shields first, they can rust overtime and start to fall off.

You can also check the rubber exhaust mounts to see if they are ok, again overtime these can split and wear causing more movement of the exhaust. Doesn't sound anything major wrong to me and a simple/ cheap fix really.

Appreciate the advice, I’ve had two services this year and nothing has come up on the diagnostic check so was pretty confident it’s nothing major but it’s good to have the peace of mind. I have had a heat shield taken off due to it also making a noise but I can’t actually remember which one it was. Hopefully it is as simple as this, will have to get it checked out anyway. The noise is doing my head in xD
 
There is an exhaust manifold heat shield, cat heat shield and ones along the mid pipe, when I had a catback fitted once warm it would have a rattly noise that you are describing, I bent part of it back a bit and no more issues.

It would’ve been the manifold shield I had taken off then as I remember the noise it made was coming from infront of me rather than below the car, that’s good to know anyway thankyou mate
