Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion

Firstly put you hands through your wheels and check your disc sheilds aren't loose, then walk round the back bumper knocking it with a knuckle and listen for any rattles from the heat shields.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Just on the offchance someone might be able to point me toward things to check... My car makes a gentle rattle for a 1/2 sec as the revs rise under load i.e 2nd or 3rd, as the revs pass through 1800rpm. Sounds like something loose or resonating in the engine bay area or exhaust. I can only hear it with the window down. Sounds absolutely fine otherwise, and not a big issue at all, but always like to fix things if I can.

POST 2Original post

Firstly put you hands through your wheels and check your disc sheilds aren't loose, then walk round the back bumper knocking it with a knuckle and listen for any rattles from the heat shields. If it's non of them, then its a case of feeling round your engine bay for anything that may resonate.

POST 3Original post

Also, if you've got someone to help you, start the car, leave the handbrake on and try and set off holding your revs around the point it happens whilst the clutch bites. This will place a load on the engine same as when you're driving and hopefully replicate the noise. The other person can then poke around and identify where it's coming from.

POST 4Original post

If a standard Porsche exhaust, it could be internal baffles working loose. I have had this in the past around the rev range you mention. Had the boxes split open, baffles welded in place and put together again.

POST 7Original post

I had a rattle from one of the exhaust clamps rotting through (the bolt corroded and snapped). The clamp remained loose and rattled around.

POST 8 / ORIGINAL POSTEROriginal post

Thanks folks for all the ideas, I'll have a good dig around at the weekend.

POST 9 / ORIGINAL POSTEROriginal post

So yesterday, trying to fix another fault I removed a flint pebble that was stuck between the silencer and heat shield. I also found that the PSE actuator is loose, which I will reattach or replace. Fingers crossed it was one of the two causing the noise.
