Thread: Td5 turbo whistle

Might be that the rubber pipework in your engine bay needs to be replaced.

That's what happened on my D3 a couple of years back - replaced the rubber with silicone and that seemed to solve the problem. I could hear it noticably thru the AC vents which I thought was unusual.

Manifold? loose hoses?

Hi Noogie, when this happened to my TD5 a couple of years ago it turned out to be a broken exhaust manifold stud allowing the gases to escape through a tiny gap. You may be able to see black marks around the area of the manifold which would indicate where the problem is or you can listen with a short length of garden hose to try and locate any different sounds in the exhaust manifold area. The last is impossible to do while driving so is not a good guide if the noise is only audible under load. Cheers, 130man.

Yep, my money would be on manifold stud(s) sheared.

+1 broken stud. Manifold is probably bent like a banana

Haven't you done the exhaust manifold studs previously Mick?

Yes I did my manifolds studs a few months back, but reflecting back I remember he didn't replace one as he said it looked ok.

I'll have a sniff around.
Thanks for your help everyone.
