Switch between Lever type and Film type fuel sensors

Hi everyone,

I have also the problem with my film sensor for fuel. The main problem i have is the cloud aplications where you can switch between film or lever.
I try both, but the at the begin looks everything fine, but in one hour nothing happend. On the screen is only " Changing the ECU...".
If i stop the switching and look in the controler looks that the ZFE has changed the sensor type, but when i look real values for the sensor i have only in the heater voltage 0,01V everything else i zero.
By the Film must be Inductive fuel sensor Enable or disable???

Skim:
I'm not expert at this, but if I understand you correctly, the switch from 'film/inductive' to 'lever' was made to the ZFE controller by GS-911?

If so, this alone will not solve the problem as the current values received from the sensor will not make sense to the ZFE.

You firstly need to do the pin change on the ZFE plugs.

Then you either need to fit a lever unit to the tank and modify the wiring/connector to connect to the lever type. If it's not possible to fit a lever type to the tank, you can fit a resistor across the relevant 2 pins of the existing wiring.

In the latter case you will of course not have actual correct fuel level displayed but you would have gotten rid of the flashing warnings.

If my assumptions are correct and you need more info on pin numbers to be swopped and resistor values, I can let you have what worked for me in terms of not being able to fit a lever type into the tank, but only to fit a resistor to fool the ZFE unit into not displaying warnings.

Good luck and keep us posted.

 No i dont want to install the lever, i repalced the film strip with the new one. I think i have now problem with the coding the ZFE.

 When i want change the coding the ZFE with GS 911 it takes a lot of time but nothing hapend.

 The second question was what is correct, because you can choose Lever or Film and Inductive fuel sensor Enable or Disable. My opinion is that by film strip sensor must be enable.

Skim:
The way I understand, if you just replace a failed strip, you do no changes to the ZFE.

Thus 'inductive' should be enabled.

You only need to recalibrate the new strip outside the fuel tank using the GS-911, which you probably did.

mathiasslo:

 Ok, now i know when i have film sensor, inductive fuel sensor must be enable.

  Than the second point. I was trying to change the ZFE to lever, the GS 911 did something, but the procedure is not ending so far.

  Now i want to chnage back the ZFE to film and i try wit the GS 911 in infrastructure mode. The begin looks good, but after one hour i have stil on computer Canging ECU.. and this is it.
 
  How long takes the GS 911 software to change between lever and film. With te calibration of the new sensor was everything OK, but i think that my ZFE has still a wrong coding.
 
  What do i wrong that the procedure with the changing goes not to te end?
