Hello, I have a Golf II (Otto Motor, GKAT, 40KW, four-speed gearbox), which unfortunately does not give me much pleasure at the moment: If I drive in nice weather, everything is still ok, but as soon as it gets cold and wet (e.g. driving on wet road in heavy rain) the engine starts spinning: The car suddenly loses speed, although I give as much gas as before (It is as if you suddenly completely get off the gas. You can even go full-speed. It’s time for me to slow down on the motorway from 100 KM/H to 60 KM/H. If I don’t switch down, I’m getting slower and slower. If I turn on the car (or the engine) I get a push and it goes back for a short time, but then it’s much worse to repeat myself, so that I can only crawl over the highway with 20 KM/H. The mistake occurs when it occurs all the time. Even if I drive down from the highway and continue on the highway. It even sometimes goes off at the traffic lights. I also tried once if the error occurs to completely penetrate the clutch and give full throttle. It does NOT happen. The engine does not cry. Only after a few seconds. This occurs at all speeds and speed ranges. I have already exchanged the following things: – Fuel filter – Temperature sensor of the Lambda probe – Air filter I would really be happy if someone could help me! Bummal
