I didn’t find anything suitable with the SuFu. I recently had the following problem: The first time I noticed this already months ago. I was standing on an edge (no curb) backwards on a slope and had to give a lot of gas to get over this very easy elevation. The same time in a parking lot, but on a flat surface. I had the impression that the Diva had to struggle hard to get over the light edge from the stand. Yesterday (I have now 80000 on the speedometer) I parked backwards on a middle slope and I had to give a lot of gas so that the party got a bit back in motion. One could sum up briefly: the whole seemed quite powerless. Already on the way there over the highway I was mercilessly pulled off from a pass on a straight track and even on a slight climb, and that in S-mode. I had the FSP read out a few weeks ago. No mistake. What can that be (again)?
