OK, but the accuracy of the "instantaneous fuel consumption" is my second concern. My first concern is the time needed by the "instantaneous fuel consumption" to hit the 0.0 l/100Km (or 999.9 mpg). Why it needs about 10 seconds for this? The engine is under zero load since the moment I lift the foot from the accelerator pedal. It looks to me that the "instantaneous fuel consumption" behave like an "average fuel consumption for the last 10 seconds". Can you please check if your C3s are behaving the same? If not, I may have a problem with the engine management. During drive tests, I've checked the "instantaneous fuel consumption" on a Skoda Fabia and a Seat Cordoba and for these cars the "instantaneous fuel consumption" reaches 0.0 l/100 KM very quickly (about 2 seconds from the moment I lift the foot from the accelerator).

Hello, I'm owning a C3 1.4i, 75 BHP petrol engine (TU3JP). I noticed a somehow strange behavior of the trip computer: When going down on an incline and doing 'engine break' (sorry, I don't know the exact term - I mean pressing no pedal so the velocity is kept constant by the engine resistance) it takes quite a long time (~10-12 seconds) for the trip computer to finally show the '0.0' instant consumption. The instant consumption is slowly decreasing from its 'straight & level' value (for instance 6.5 l/100Km) to the 0.0 l/100 Km. On other cars I drove the instant consumption is going to 0.0 far more quickly (max 2-3 seconds) during an engine break. Are your C3s doing the same or do I have a problem with the ECU? Thanks a lot! P.S. Sorry for my poor English :lol:
