Good evening, I bought a Laguna 2 Ph1 2005 1.6 107hp 133000km. According to fuel monitor etc. it does not consume much. Short look into the onboard computer and I thought of the blow. According to the onboard computer a consumption of 11.4l. Got it with 11.4l consumption. I drive with approx. 1900-2000U/min, accelerate not too hastily, switch 2-3m in the 1st GANG into the 2nd gear, at 25-30km/h into the 3rd gear and below 50km/h in the 4th. Drive 80% inside short distances, but 11.4l Su per for the car is not much, but exploitation. The car was a workshop car for customers etc. who left their car there and otherwise on behalf of the workshop on the way. My question now, can one put the on-board computer on 0? So reset, so that the on-board computer comes to factory condition. MfG
