Ok so things are really not great!
As I started the car from cold and accelerated gently out of the office the car was making a whistling/squeeking noise which went away after it had got to temperature. I haven never noticed it before, next things i then noticed is the exhaust is a lot quieter and to top it off it just isn't accelerating as well as it did especially in the higher rev ranges.
Something is really up with it and i fear it is the turbo :(
