@Dede: Herzlichen Glückwunsch zum Erstsieg!
Der Knoten ist geplatzt und ausgerechnet da war ich nicht dabei - schade! Hätte zu gern Deinen Dank an die Crew über den Boxenfunk mitgehört.
@Christain: I also had a G27, working like a charm for many years. When I sold it, it started with the same issue: the center moving to the left more and more. I took it back from my "customer" and had the exact same issue myself, no chance to finish a race anymore. I finally sold it as a spare part. Maybe it´s about tiime for you as well...
