My H-1 accelerates independently in the roundabout. Reproducible!

Hello community, so far I hadn’t talked about it, because I thought that if you tell someone, then come and get yourself. But now I just had a brittle situation on a supermarket parking lot again. The problem persists since the first registration of my automatic H-1 in 2/2012: I leave the parking lot of my bank with a warm engine and roll about 40 meters in step speed to the narrow roundabout, which I have to circle around once completely. After a quarter of a distance, the motor starts to increase the speed independently and sustainably. A switching process does not take place. The surprise moment ends after approx. 3-4 seconds without further intervention. The speed reached is then actually already too high for the roundabout exit. This process can be repeated at any time. There seems to be some connection between the danger On several occasions I had tried to recreate the situation in an empty parking lot, but I only managed to do so twice. Unfortunately, the parking lot was well occupied this morning and I had not even thought about the self-acceleration. Anyway, I could slow down in time. Do you have an idea about cause and effect. With my workshop, I would be very interested in the topic very much. After all, I can’t prove anything. Greetings and good driving Rüdiger
