Hidden 6 shows the liters in each side. Here are the basics to know if the senders are working properly;
When the left gets below about 25L, the right should stay at 1.4L until the left reaches zero.
If the right ever gets down to 1.0, refuel immediately regardless of left fuel reading.
Typical scenarios:
Left side has 17L and right starts dropping. This usuaky means the siphon jet is not working. This is the classic tm ran out of gas at 1/4 tank problrm. You actually do have 1/4 tank you just can't use it.
You can get very similar symptoms when the left sender unit is reading high. The main difference is that the level can be anything and the DTE will get stuck (when it happened to me my gauge read about 1/3 of a tank).
When you suspect a fuel system problem watch test six.
The right side should stop dropping when left is 25-27L and if you see the right slowly drip from 1.4 to 1.0, that's a sign the siphon jet is not working, but of the right side drops quicky from 1.4, the left sender is more likely the fault.
If you fill the tank and it shows 2/3 of a tank that usualky means that the left sender is reporting high (seems illogical: why if it reads high does the gauge read low: has to do with how it shows the average over time) this is why is important to reset with 21 if you work on the fuel senders.
