Hello, dear, a friend of mine is driving a Smart fortwo 0.6i Turbo (MC01) Coupe Bj 2001 No workshop could help her further without making any assumptions ….maybe YOU have an idea. She described the following problem: Smartie starts to make problems as soon as the temperature indicator shows 3 eggs. He hops briefly … then goes out. If you try to start it then the engine either does not start, or if it starts you can’t turn on a gear. As soon as it is cooled down again it starts again. Error message which it shows… in the middle where the gears are displayed 3 strokes between each other. Also on the right bottom a yellow indicator that does not run out anymore. Noise when I turn it on (if it is possible) is a glimmering or knocking …. I did not have any other abnormalities, otherwise he drove without problems. I would be very grateful about your help.
