Recently, just a few days ago, my turbo spools a lot louder than before. Almost like a vacuum cleaner. Not sure what caused it but no engine or warning lights and drives the same still. Maybe it's just in my mind or didn't notice it before? Any recs on what to do or check?

 

Gotta be something intake related. Have you checked the filters, or the intake pipes?

 

I haven’t but I dropped it off at nearest Mercedes, they’re checking it.

 

Dyson V8 animal inside... Jokes aside, agree it might be an intake noise, something might had somehow came loose so you can hear it especially the insulation part of the engine.
