24 FL5 squealing when letting off accelerator

While driving today I noticed this noise when the windows are down. I can’t tell what’s causing it or from where.

I listened to that with headphones and I still can't hear any squealing sound.

I wouldn’t call it’s a squeal per se, what it’s definitely a high pitched sound as soon as I let off the accelerator.

Update:

I just went out for a drive and went around 40mph noticed the sound got louder. I also noticed that if I put the car in neutral the sound goes away. If I engage the gear again then I hear it again.

Wastegate rattle? Normal if so.

That's exactly what it is then. Wastegate rattle. It's totally normal.

You have a few options:

• Learn to live with it.
• Drive with your windows up.
• Keep your foot on the throttle slightly when in gear.
• Trade the car in for something naturally aspirated.

I've been wondering what that noise is too. Sounds normal so I never complained. Thanks for sharing.

Just noticed the same noise yesterday, was concerned it had to do with the sprint filter I put in or worse. Never heard this in any other turbo car I’ve had before, glad to hear it’s normal apparently

What’s funny to me is that I’d say I’m sensitive to rattles, but the wastegate doesn’t bother me at all. I think there’s a few factors to that, though : 1. It is part of the normal engine noise (for this car and apparently some other makes/models). 2. I don’t tend to drive with my windows down. 3. Maybe mine isn’t as loud as others’, though I doubt it.

Roll with it. It’s just a minor quirk of the car…and it’s a GREAT car. If anything, maybe install a louder exhaust.
