Hello, yesterday I found that all at once the performance is missing when speeding up. the car drives quite normally only you have the feeling as if the half of the ps is missing. if I start the car again everything is normal again until the performance goes again flutes. otherwise no jerking or so. ruckel is only when speeding up the full performance is there. when the performance is gone, is also the ruckel gone! jemannd has an idea what that could be. achja. bj 2004 , 2,0 diesel 225 .000km. thank you
