-> Value

1. Did you drive the tank completely empty after making this change -> You have to drive the tank completely empty to get a usable value!

2. What was your actual consumption (calculated) ->

- Total distance with one tank filling -> 430 km

- Refilled amount of fuel -> 48 Liters

- Actual consumption (not BC) -> 11,16 Liter / 100 km

3. Compare the actual consumption with the indicated consumption in the BC.

4. If the displayed value in the BC is higher than the actual consumption, then you have to go down with the "cc value",

If the displayed value in BC is lower than the actual consumption, then you have to go up with the "cc value".

5. Start with 200 steps and find out with every refueling!

This is a very lengthy process, but I had also to go through this and it is not possible otherwise! ;-)

I hope this helps?

Won't driving the tank completely empty risking of damaging my dual fuel pumps? That's my main concern

No, you do not driving the tank completely empty!D33@+H-Kn1gH+ wrote: ↑Thu Aug 22, 2019 1:26 amWon't driving the tank completely empty risking of damaging my dual fuel pumps? That's my main concern

You misunderstood me!

Drive the tank to 47-48 liters empty (50 liters fit in).

So that still 2-3 liters are in the tank.

That's enough for the calculation.

That's what I meant!

Okay but how do I know when I will be at around 47-48 liters since the fuel gauge is wrong? Is there an average distance for that?R-12914 wrote: ↑Thu Aug 22, 2019 3:20 amNo, you do not driving the tank completely empty!D33@+H-Kn1gH+ wrote: ↑Thu Aug 22, 2019 1:26 amWon't driving the tank completely empty risking of damaging my dual fuel pumps?

Please post a picture of full Tank and one after 200 km driving (from the gauge).
