2010 R1200RT Fuel strip advice please

(1/3) > >>

Skim:
Since replacing the battery with a new one a week ago, I had the typical fuel strip failure symptons. Yellow triange warning and fuel level showing "Empty".

My question... this is an intermittant fault. It normally works when I start the bike. Fault appears after travelling a short distance and often disappears and everything works fine again.

I was under the impression that the fuel strip failure is sudden and complete. Do I need to look for something else, wiring etc? Saw the 'Piezo zap cure' clip on You Tube. Seems to be worth a try?

Thank you in advance.

Inspector Gadget:
I would first connect-up your GS911 and check if it is indeed noted your bike is with the Fuel-strip, instead of the floater-type.
Because BMW changed to the Floater-type per august 2010.

As you only changed the battery, it could be calibration if off for your fuel-strip (and prior to that battery-change was probably just within the calibrated range).
So it would merely doing the re-calibration of the fuel-strip (via GS911) would be enough for your problem.

Skim:
Thank you for the prompt response Inspector. Checked. Definitely "Film Type Sensor".

May just add... The yellow warning triangle on the dash does not flash, it merely stays on.

When the fuel gauge starts working after having been off, the remaining indicated distance on fuel gradually and slowly increases by 1 Km.

Inspector Gadget:
Sorry for you, the Fuel Strip isn't BMW's best implementation.

Did you connect-up the GS911 and did an auto-scan, were there any errors noted?

The non-flashing yellow is the warning-level, together with the flashing fuel-sign indicates the "regular" reserve-fuel situation.
The non-flashing yellow can only flash in red (or non-flashing red too, btw)
It can not and deos not flash in yellow AFAIK and according to the manuals?

I still think you should consider re-calibrating your fuel-sensor.
But you can first try to do the Piezo zap method, if that resolves it.
AFAIK the Piezo zap method never hurt the level strip, only resolves the impeding issue. Sometimes.

The actual fuel-level is only measured after a substantial distance has been traveld I'm told and then updated at some intervals.
And when you start the bike it merely just shows the last remembered state (level).

I do believe your calibration is off, but you could be right that your fuel-strip is on the verge of failing.
It is the micro-fractures and therefore change of resistance that is causing the infamous issue.
And the micro-fractures being caused by the fuel-strip floating around loosly on one (bottom) end.

Skim:
Fuel guage kept failing. Will work for about half the time.

Made up a Piezo zapper as per the Youtube video and zapped on Saturday.

The guage was working at the time.

We have 2 heavy cold fronts coming through, but will take the bike for a ride and report back.
