Bumpydog Posted January 23, 2012 Share Posted January 23, 2012 Our 2004 TD5 ES Auto started to make a screeching when accelerating under load (sounds *exactly* like a belt slipping). It was taken into a local LR dealer for a different issue (recall) and they said that it was the turbo making the noise. Rather than spending a grand at the dealership, I bought a genuine turbo from the UK (I am in Ireland) and my local mechanic changed it but it's still the same. He seems to suggest that the wastegate isn't opening properly. Does anyone have any ideas of what might be causing this, as he is running out of ideas. Should he try bypassing the wastegate solenoid? Thanks. Quote Link to comment Share on other sites More sharing options...
