Hello, my son drives a 176 year 1996, 1.1 ,4o kw 147 tkm, on the highway at approx. 120 km/h the temperature indicator went on, the power fell to 80 km/h, he immediately ran right and called the ADAC,(motor no longer starts) who said that the ZKD was broken, in the workshop you said that if the power drops mostly also a motor damage the case is… who has had such a thing?
