Fuel film strip problem
Ghiribizzo:
I've previously replaced 6 strips on various GS and GSA bikes. Not had any issue doing this before - replacement strip fitted, calibrate with GS911, put it together, fill with fuel. ✔️
I've fitted two used strips with success, the others were new.
So - 2007 GS with a non operating fuel strip.
Owner got a used one sent. Whilst it was on its way the tank was drained and dried out.
The bike was getting new WESA shocks too.
Strip arrives, connect it up and it would not calibrate.
Cue me being angry with the supplier. Double work etc etc.
I got a new one from BMW. Fitted that. Same issue. [emoji33]
Bike had only the fuel strip issue as an error code and also a low voltage one.
Once codes were erased i tried again. Same issue.
Fault recorded. Only for fuel strip. The battery is now out and on charge. The voltage was showing low on pc at around 11.7V.
I'm hoping i'll take a decent charge, if it doesn't measure up i'll swap it out for one from my own bikes before trying again.
The issue of course is why did the 'used' and new strip not calibrate?
Is that low voltage an issue despite the voltage not being low enough to record an error? The three plugs are connected as they should be.
Anyone found similar?

Hello
If there is any other fault stored for fuelstrip except "no calibration done",
the calibration function will be rejected.

No, there are no other faults.
I updated to the latest software version and charged the bike's battery. I'm now wondering if the strip that was in the tank when it was brought to me was (is) ok. The 'used' strip supplied and this new BMW one show the same issue.
There was no problem connecting the strip's cable to the pump unit or the two connectors to the top of the pump.

In the past when changing these I've always just deleted the recorded fault code and then proceeded with calibrating the replacement (fitted into a completely dry tank) then adding fuel. Never had any isdue where a used and a new strip would not respond.

Hello
The fuel level sensor is controlled with an on-board power supply.
If the tank level sensor is immersed in fuel and so will be cooled, ~11 volts approximately must be measured at the pins.
If the tank level sensor is not immersed in fuel, the sensor's resistance changes and the measured voltage value decreases slowly to ~ 5 volts.
The power supply for the heating wires pin 1+4 of the sensor comes out of the ZFE.
I think the heating element is damaged.
