Hello, I have a “new” XC90 D5 Geartronic, EZ 11/2009. With the car I have the following problem: It does, if you take away gas quickly in the area of approx. 2000 Umin a hissed turbocharger-ablass noise. (According to workshop normal, nevertheless my 2004 XC never does.) But the main problem for me is that it also makes this rather unpleasant noise (so blows off pressure) when it turns up, especially from the 2nd to the 3rd but also in other switching operations. sometimes this stuttering blow-off happens even without switching (Manuel 3.Gang). You can see very clearly that the tachometer needle pulls away with the sound down (turns out). The whole thing is very unpleasant when driving, not really appropriate to a 55t Euro car. And I personally know such a thing of no turbo diesel. Basically, the sounds only appear when it goes uphill. Rarely when it is flac h is, Bergrunter never. The workshop (very hard to do nothing to complain) has now (on suspicion) changed the intake resonance tube, but the ruckelei and the noise have remained. Tomorrow I will drive another D5 for comparison, because allegedly (Volvo) is the “stand of the series”, but it would seem VERY funny. Could someone with similar vehicle or experience tell me something about it? (There are hundreds of entries about noises, but I didn’t find anything for that purpose. (-) ) Thorsten
