Hi,
I am from Czech Republic, so sorry for my english.

I have Laguna I with 1,9 dCi engine, manufactured in year 2000.

Is there anybody with same model and engine? I have problem with on board computer, which does not show the fuel consumption (average or actual). I tried to restart computer with pushing button on dash-board and pushing button in lever at the same time. But no succes. I tried to disconnect accumulator too, but no succes too.

Please, what can I do??

Thank you for answers

On board computer did not show any information about fuel. There are only flashing dashes. Man, which had a car before me sad, that showing a information about fuel was OK to some time.

I have this type of on board panel


But it is strange, that I can´t make a restart or get to servis menu of on board computer. Maybe I do it badly.

Yes, i can change display to show other information. On board computer did not show any information about fuel. There are only flashing dashes. Man, which had a car before me sad, that showing a information about fuel was OK to some time.

In my car is full equipment, there is not only navigation, speed control and elektrical settings of seats.

If you have that sort of equipment level I suspect you should have the fuel consumption on the computer, it may be an issue with a sensor.

With the ignition off, hold the computer button on the end of the wiper stalk, turn ignition on (don't start car) and the system should self test. The dials will step forward and back and the readouts will flash through various numbers.
To put back into normal mode, turn ignition off and back on.
This may help
