Hello, my V70 chirps on the first approx. 15 km while accelerating. There is nothing to hear when giving gas in the stand, I accelerate out of the speed cellar with a little emphasis (no full throttle, engine is not yet warm), a chirping is clearly perceptible. If it were to occur in the stand, I would tap strongly on V-belts, also sounds like that. Since it only occurs under load, I rather tap on the turbo charge. It is definitely not a normal loader whistle, I know that very well, driving exclusively turbo engines for 10 years. Did someone have the noise and know what it is about? Have a nice evening.
