I have now used my new FK 3 for 1600 km and had to go to the workshop for the first time because of various problems. I also have the tank cover problem, which is suffering in this forum, which is surely now known by every FK driver. Furthermore, my automatic climate control blows immediately full pull when setting AUTO after the cold start, although it should only blow more air into the interior when warm air is available. So it is at least noted in the manual. However, I discovered a defect more or less by chance. I had looked at the course of the exhaust system for the sake of interest and discovered that the shock absorber at the rear is losing oil on the right. Maybe you can also look at your vehicles if this is okay. When I came to the workshop with this diagnosis it immediately sounded to me that this could not be. Small sound, however, was admitted that I was right. Of course, in the next few days everything will be repaired or replaced on warranty.
