Hi all,

just read in an old post, that if your turbo is making a whistling sound, like a distant police siren then it is most likely knackered. ive recently bought my car an e280cdi sport 2005. 66k. the acceleration from idle is as it should be. however, acceleration mid range is slow with delayed kickdown. i do here some small whistling like a police siren in the distance. does this and the symptoms indicate a knackered turbo.

i took the car back to the dealer as still under warranty. they did some software updates which seemed to help but did not pay much attention to the whistling i pointed out, saying it is normal for a 60kmiles car? are they correct or should i try and push for a turbo claim before warranty ends
 
Hi, can anyone else help on this as well? should there be a certain amount of whistling from a turbo that has done 60k. e280cdi sport
 
I can hear my turbo whistle if my windows are down and i'm going slowly but never heard it inside the cabin
