Hi,

I have recently purchased a 2007 grand scenic 1.5dci.
car seems ok except for one thing.
Whenever i lift off the power i hear a whistling noise, a bit like a dump valve.
I know this isn't normal for this engine as my previous car was a 2006 megane 1.5dci, and I never heard the sound on that.
The sound isn't there whilst accelerating and only seems to do it during the first 2 gear changes. It can be heard inside and outside the vehicle.
i wish i could explain the sound more.

Hope somebody could shed some light on this as I am panicking that the turbo is about to go kaput!

Thanks in advance.:confused:

Hi, my 2010 Grand Scenic 1.5 dci Dynamique TomTom also whistles between gear changes. It has done from new and the dealer says it is normal. Hope this helps
