Hello together! After my S60 D5 has now been changed in an all-round action of the timing belts and unfortunately a new coupling was due and the moose is now re-renewed (160.000 km inspection) ready for the next 160,000 km, now I noticed a phenomenon, which maybe also other moose drivers had after such a repair?! And it is now a turbo whistle to be heard, which was previously in this volume and tone situation not so present. In addition, a very easy rattle can be heard in the stand, which was not there before. This really only light rattle develops under load then just into this loud turbo whistle. The KfZ-Zauberer of my trust has therefore today again looked after everything, whether any hoses etc. were not properly tightened, but it is all absolutely dense and the performance is also fully there (there you may first notice, as the elch with new clutch again really bites :-). Therefore my question: Did one or another of you already experience something like that?
