Hello everyone, I’ve been a Forester Diesel for over three years. I’ve driven about 100000 km now. The problem: I found a clacking noise (an extreme nailing) at the speed up, which then goes away again. Several times the valves were calibrated, on the computer. It was also determined that the vehicle did not do this alone. What should be in the state. After audition and trial driving by the master of my dealer were then at about 85000 km the injection nozzles changed to Kulanz. After that everything was fine. I drove now 100000 km and it starts again and that always in a warm condition. My dealer says now we have to look again. Of course the guarantee has now expired two months!!! Does anyone know the problem? Or has one of these heard already? Who can help me???
