Compared to my last XC90 D5 185hp(EZ 11/05) the turbo whistles clearly with the modified (equivalent engine EZ 4/06), in addition comes a fire that goes lgs. on the nerve. Sometimes sounds like an automatic mofa. Does anyone know that? My friend says the resonance body has been changed in the meantime and everyone is whistled now?!? Is that true? Besides, the steering is crackling at the end of the steering impact on both sides, was not at the same time. Don’t be sure to fix that the frdl. Does anyone else think that? In the old case, the exhaust tailpipe was still bright after 10000km, now already after 2000km black. In the meantime another particle filter was installed which is absolutely maintenance-free, in the old case a cartridge has to be changed after 100000km (300.-Euro). I assumed that the first one had a completely maintenance-free particle filter. Thank you for your answers, Greetingol
