Badger90 Posted September 18, 2010 Share Posted September 18, 2010 Afternoon. I have noticed the other day that my turbo is sounding differnt to it used to, At 2500rpm it sounds normal, but at 3000rpm above its skreaming instead on whistleing. Reason I ask it that I got a leaflet at the LRO show about turbos.. I dont know if you of you got one, it was in the freebee bags. And it said for noisy turbo, air pipes split or poped of, broken gaskit or knackerd turbocharger? I would like a secand oppinion in this please? Its done 230000 miles.. well the engine and its the original turbo!.. Cheers Sam Quote Link to comment Share on other sites More sharing options...
reb78 Posted September 18, 2010 Share Posted September 18, 2010 Can you post a video of it with sound? If you've checked the air pipes, i guess it could be the bearing. Is the oil feed and drain to and from it ok? Quote Link to comment Share on other sites More sharing options...
gti-90 Posted September 18, 2010 Share Posted September 18, 2010 hi, i had a similiar problem with a 300tdi that had done 160,000. the turbo as soon as you reached the boost part of driving would squeel, after alot of head scratching, going around the pipes looking fo splits etc. turned out to be the wastegate flap inside the manifold was slightly loose causing air to escape. hth cheers.

Marco Posted September 19, 2010 Share Posted September 19, 2010 I've just fitted a new Turbo to my 200Tdi, same type of loud noise at 2500+ revs, tightened all manifold & turbo nuts and that made it disappear. Suggest to check for (air) leaks first. Cheers Marco Quote Link to comment Share on other sites More sharing options...
