323001396 - X001 EXCESSIVE FUEL CONSUMPTION

The engine operates in a way that appears normal, but the fuel consumption is higher than that recorded in the past. The consumption data recorded in the vehicle technical documentation is defined during the course of approval tests in accordance with directive 1999/100/CE.These tests simulate an urban cycle and an average non-urban cycle and therefore may not be representative as fuel consumption depends a great deal on driving styles
