Good day people, update: V-belts were already worn out and is therefore torn.. have changed both rib belts With steering roller and tensioner. So far so good. Now I have about 2 weeks after installation time and again with longer drive the message “generator fault maintenance urgent” is now again in the workshop.. which will find at the read out nothing because the error is not permanently stored or shows up. I was now told that all is correctly installed and the light Aschinen belt drive is also free. He would appreciate that the alternator gives up the mind and would change it. What do you think? Can it be something else or is it advisable to follow the assumption? Or maybe change the controller with coal yourself? Am at almost 290.000km is the first light machine If it should be done what cost come to me? Thank you very much already people love greetings Toni
