Hello Moose friends, need urgent advice! A few weeks ago the ZKD and the VSD were renewed due to blue smoke and high oil consumption in my 850s. 2-3 weeks everything was ok, then the same problem appeared again. Even after replacement of the oil trap no improvement in sight. I used to drive with 10W40 now 5W40. Fear that the piston rings are no longer in order. Is there still hope for my moose? Next month the TÜV is looking forward to your tips and ideas. n … “who rides the moose”
