Gregski Posted September 8, 2023 Share Posted September 8, 2023 2.0 TDI - Is this normal sound when lifting off the accelerator? For me it comes from air intel / air filter ? IMG_1666.mov Quote Link to comment Share on other sites More sharing options...
FMOB Posted September 10, 2023 Share Posted September 10, 2023 Definitely terminal, I think the gangle pin in the giggle box hiding under the air filter is shot. Only fix is to scrap it, sorry to be the bearer of bad news. Am I doing this right? Quote Link to comment Share on other sites More sharing options...
Optimus Posted September 11, 2023 Share Posted September 11, 2023 Really hard to diagnose over the video. It might be bearings on the turbo. The sound normally is a hissing-rattle sound more noticeable as the turbo looses pressure the slower rotation causing radial movement of which if the bearings are going/gone the sound becomes more pronounced compared to a high pitched hissing/whistle which sometimes we can’t hear because it’s higher frequency or mistake it as air suction.
