My V40 sometimes has a crackling tweeter on the driver’s side, so I thought. The friendly one, however, said that the tweeter was healing and it was the disguise. At the front left of the window he made the plastic cover underfeed this and said the sound of the tweeter was now gone, would swing up until then. So far so good, noise was really 10 days away… now with the temeperature fluctuations very warm, now again a little cool r the sound was back this morning, when I had pressed the cover of the door again the noise was then gone again… tonight then again, as soon as you push the door panel it is better. Is that the tweeter or the door panel? Are the warranty cases, the car still has 10 months warranty. The friendly said a new panel does not pay any guarantee of the world. What should I do? In addition, a noise always comes away towards the glove compartment, more so right Do you have that? Generally, the V40 rattles a lot is the quality so bad? Thank you for your efforts already.
