Hi, I checked my operating instructions and found this point. Drive Astra K with automatic. Grad in winter it is known that the things switch ultra high in order to bring the cat to temp.. But this is rather beneficial for wear or not? With the hand switch nobody gets the idea to beat the engine over 3000U. But why is it that way with the automatic? What is meant by “limited” speed with Opel but also with other manufacturers? If my engine is cold and I kick it then the speed goes up as well. Somehow I don’t understand this point. The engine should be protected, but ONLY, if you drive a switch or what? degree of turbo throws away with such a treatment.
