991.2 GTS unusually loud turbo noise (video)


PCGB Member
Bought my first Porsche! 991.2 Carrera 4 GTS - Carmine Red with a 7spd manual box (image attached). Couldn't be more thrilled apart a few strange metallic rattles from the rear, but more importantly, an intermittent extremely loud turbo 'whoosh' sound.

I have attached a video link below to illustrate the issue, but I would also note that 1) on the first few hard pulls the sound is normal with no whoosh 2) after the first few pulls, or more enthusiastic driving, the 'whoosh' starts 3) the car drives normally 4) seems to pull the same in either case. 5) the 'whoosh' sound is much louder than the video suggests!

Perhaps a hose is loose?

This issue started when I was on a dual carriageway with several roundabouts, and accelerating hard from low to medium high revs out of each roundabout in third gear.

Have sent a video to the OPC I bought the car off a few days ago.

Any thoughts greatly appreciated, I couldn't find a thread that described this specific turbo issue!

Gorgeous car (looks like mine [;)]). I've had my GTS since new and haven't experienced anything like this. Clearly you should have your OPC look at it. Sounds like something which will be covered by warranty. Let us know...
Enjoy the car!

Diagnosis was a hose that had become very loose. Simple fix with OPC under warranty - reattached said hose. Car driving well.
