Hi everyone. I have a 2006 model audi a4 1.6. I have problems with electricity. Even the engine is running or not running the car's exterior lighting, air conditioning, window control, dashboard turn off for a second and then turn on again. interior lighting is sometimes turned on by itself. I changed the battery, bcm and fuses. I checked ccm and there is no water. Sometimes the window control button triggers this fault, electricity is cut off for about 10 seconds and the radiator fan is running. Should I change the ccm? I'm sorry for my bad english. thanks for your answers.
