Hello everyone, what happens when the automatic air circulation function is activated? Actually, the air circulation should be activated in case of bad odours as far as I remember. But if I drive past a field stinking of slurry it still stinks insanely in my car. Is the function somehow defective? And how does the recognition of bad odors work? Ds only thing I could determine with activated function was an increased fuel consumption by approx. 0.5 – 1.0 liters to 100 km. Gruss capdoc
