Just got an e30 320i and my fuel gauge is acting up. It jumps to full and sometimes stays there and when i press the km distance button the fuel gauge would jump also. With the distance km read out, the bottom one doesnt work. And also with the km/l gauge it isnt reading the right thing. The needle would go completely around and wont see it. Would i have to go to an auto sparky or can i do something myself?
Also my drivers side window is not working but passengers is. Old owner said hes changed the button twice already and still doesnt work.
