I have recently realised that my VS Berlina is chewing the fuel. I'm currently getting 16.4L/100km. I've renewed the high tension leads/spark plugs which made a slight difference. Upon inspecting the Oxy Sensors one of them was white and the other was black, so i replaced the black coloured one but didn't notice a major difference in the fuel economy. When I have the trip computer set to INST FUEL i've noticed that on the highway it shows an average of between 8.0 to 10.0L/100 but when i brake and slow down to a stop this reading increases dramatically to 99.0l/100km. This high reading occurrs every time I slow down and come to a stop. Does anyone know what may be causing this problem?
