From the kFkA thread: Quotation: @schweigers96 wrote on 6 September 2022 at 09:22:12 h: Would attach me here (also 850). Tempomat sometimes works perfectly for hours, then suddenly no more and sometimes at the beginning not at all. Sometimes it falls out when I drive over a Huckel. Presumably, either one of the electric pedal switches or one of the pneumatic pedal valves holds “just like that” and is sensitive to Wackler. (manual transmission, therefore switch/ve) ntile at clutch and brake.) The units have already been withdrawn with the method and pedal pedals are adjusted, which did not bring any improvement. There are also no error codes. Concrete question: Who has an idea of how to limit which of the four shut-off devices is to blame?
