It must be AFM, I changed a new one

Who could tell me, how much petrol left when the fuel needle at the bottom line, cause I only filled 47L the tank is full, that mean's still has 18L left in the tank, is that right?

Thanks dude, just reset the ECU and changed the NGK spark plug, could not find any different, hope is more fuel economy. Who can tell me, how much petrol left when the fuel needle at the bottom line, cause I only filled 47L the tank is full, that mean's still has 18L left in the tank, is that right?

Could anyone tell me disconnect battery from where, is it from the fuse box in the engine room or under the dash board

what's the key looks like? And where do I find the lock? Is it under the dashboard or at the back with the battery?

Is that means I just use the key to unlock the car first, then disconnect the battary?

As above, wondering how to disconnect the alarm before disconnect the battatry, and where is the negative on the battary? There are two lines, which side is negative, left or right? I have changed AFM, BOSCH fuel pump and O2 sensor, but still 300Km one tank, is it any possible with the spark plug or some other parts faulty? Thanks
