Hi all,
The turbo on my c5 seems to work ok. It has an odd feeling and sound coming from it that makes me wonder if something’s about to go pear shaped. The normal turbo whistle I get with this car(which I don’t get on my Uk car off same year) varies as the speed increases, it’s almost like the turbo has a torque converter and is changing gear... does that make any sense? Normaly the turbo whistle would increase in tone with the engine speed in my experience, but this one’s tone sounds varies as if it’s changing speed.... it’s hard to explain. I may try to take an audio recording to help with diagnosis.
Cheers
Steve

This is one continuous full acceleration in one gear, I i don’t come off the throttle. Just after half way through the turbo sounds as if I’ve just changed gear, but I haven’t.

Re: C5 2001 Turbo issue
It's barely audible, but I can just make out a very slight whine at the last third of the clip.
Turbo whine is normal - but unless it starts changing the sound and 'shrieking' I wouldn't worry about it. If you start losing power then I would do a little more investigation such as look at turbo vacuum hoses for splits or leaks.
