Occational Supercharger like sound?

[donp38]

Hi all.

I am getting occasional what sounds like 'supercharger' sound..
Would not say it is engine.
Does anyone recognize this ??

Many thanks for your input.

cheers.

Hi.

It would be a good idea to post a few more details about your issue as in:

Happening on cold start or when warm?
When driving or idle?
Does it get worse when apply the revs when stationary?

Or a short narrative as to when you think this is happening.

Please post details of the car. A lot of forum members put these details in the signature strip (see below) so that way the information is always available.

That way some of the more knowledgeable members in this forum, not me I hasten to add, may be able to assist you.

You never know - it could be the supercharger failing!

We need more info on the car and a recording of it.... Maybe you do have a pes G2 supercharger on it and don't even know it

Might be linked to the A/C, see if the sound is still there with the 'Econ' mode on.

The usual culprit for such a noise does tend to be one of the spinny bits on the front of the engine

Possibly PCV valve, but as others have said, we need more information on engine details and conditions under which it happens. Even better, video it so we have the exact audio as well.
