over the last couple of weeks i've noticed a noise coming from the engine bay that i can only describe as a bit like tin foil rattling against the exhaust.it seems to happen at a certain point on the rev counter. i hear it just after i pull away or when i take my foot off the gas in gear and let the engine slow the car.i spoke to a guy in the know who said it would be nothing other than a heat shield rattle??apparently it's a 5 minute fix and is nothing to worry about.anyone here had the same thing??cheers in advance

Had this on my Porsche 996 Turbo and it was indeed a Heat Shield rattling.

May be slightly more than a 5 minute but shouldn't take long. Mine needed new bolts as they had rusted away. Cheap and quick fix but won't do any damage even if left, just annoying!

It *could* well be heat shield, however I also had a resonating metallic sound after a couple of weeks of ownership and for me it was one of the exhaust tailpipe trims was lose and rattling at certain RPM due to vibration... It had to go back under warranty and the re-welded the bracket which holds the tips firm.

Easy to know if its the exhaust tips, flick them with a finger or tap them with rubber handle of a screwdriver and if one resonates rather than just bangs then you know its that... Very common issue according to Club Scuderia.

Do you hear the rattle when you go up and down the rev range? Usually if it's a resonance rattle with a heat shield etc it'll do it both ways but the 430 is known for the variators making a noise that sounds very much like what you describe at around 3k rpm but only going up the rev range, you can't hear it on the way down.

If it is the variators make piece with the noise as there's nothing you can do about it biggrin A freind of mine had his variators replaced under warranty but it did not make a single bit of difference.

Sounds similar to a very recent experience. Turned out to be a broken exhaust pipe.

cheers for the replies fellas.rattle is definately both ways up and down the gears ,seems to be at about 2000-2500 revs.probably not the variators then!i've checked all four exhaust outlets and nothing loose there matt so i think i can eliminate that.all roads seem to lead to a heat shield rattle then,unless you are right adzman(and i hope you're not!!)

One pipe is £1,100 for the part + £350 labour (main dealer). You may of course be able to get a goodwill gesture if you have a Power warranty.

Fingers crossed you have something minor.

ouch!! i'll check if my warranty covers that but my gut feeling is that the noise is definately something thin rattling against something else rather than something as "weighty" as an exhaust.if that makes sense!!

my tailpipe was covered under power warranty fyi.

Also while it was in I pointed our condensation in one of the headlamps and had a brand new one fitted, no argument.

Remember there are 2 levels of warranty, power cube and power normal. Power cube is the extension to the manufacturer warranty for those who buy their car new or used while still within the first 3 years of factory warranty. You cam extend power cube for a few years after the manufacturer warranty runs out. If you buy an approved used with the approved used warranty that's power normal and the level of cover is reduced and it does not cover exhaust. You should have a booklet to explain what's covered amd what's not smile

John.

PS, there is actually 3 levels of warranty, power train only covers the main power train, engine gearbox etc but is usually what you take out after you can no longer take out power cube or power normal.

well i opened the engine cover and did a bit of investigating.it would appear that there is some sort of box/muffler type thing on the exhaust pipe on the left hand side that is loose(the right side is tight).i quickly dragged my neighbour and asked him to start revving the engine whilst i fiddled about and sure enough the rattle comes from this loose muffler thing at about 2500 revs.anyway, rang the garage and the guy said it was a common problem on 430's and won't be a big problem.result! going in today.cheers for all the replies fellas
