My '92 300-series Disco (2.5Tdi) has suddenly come over all musical. At
3000rpm in any gear above 1st, it starts to let out a loud whistle, just like a kettle coming to the boil. I'm getting lots of suggestions, but would be interested to hear if anyone else has come across this phenomena. Is it a leaky turbo? Transmission? It only does it when it's moving, so I can't really hang out of the door and listen carefully to where the noise is coming from. Power delivery is smooth and performance hasn't dropped off at all. Any suggestions would be most welcome!
