K1200R Fuel Gauge malfunction

Postby hunters on Tue Mar 20, 2012 8:09 pm

I just filled up my bike prepping for a trip to Big Bend Texas and my fuel gauge now registers empty with zero miles left in tank. I have shut it off....hit trip meter....nothing. Still flashes empty. I suspect a sensor, but wonder if anyone has had similar experience?

its the fuel level sensor. in the K1200R, they have a strip sensor, that measures the temperature difference caused by the part of the strip submerged in gas. Those things are very unreliable. They even fail when new.
Take the filler cap off, the sensor is right there, hooked to a hinge thing. The connector is at the bottom.

You need to replace it, and have BMW to recalibrate the reserve (4 liters).

You can always just replace the strip yourself. The gasket, is good to replace it. It's not hard, just takes time. You have to remove the whole tank.
Take the screw cap at the bottom, that contains the fuel pump, and the connector for the strip. I guess you have try to disconnect it without taking the tank apart. I tried, didn't work... and I have slim hands.

Then you replace the fuel level sensor and replace the gasket.

I did it on my friend's K1200S 2007, with only 8,000km on it. Have no idea why it failed. In his case, it would always show FULL.

Good luck and let me know if you need anything else.

Eyvind- Thanks a lot! I just returned home and can tell you it's a pain in the rear to ride around South Texas without a fuel gauge. Gas stations are not exactly on every corner. I'm going to replace the sensor and let you know how it goes. Mark

Nooo! Mine failed this week and it either flashes or reads full. I very nearly ran out of gas when I parked the bike and didn't remember to fill it up; I went out a few weeks later and decided to top off. Much to my surprise it took 4.1 gallons of fuel--this was reading full.

<sigh>Anyone done this work by themselves? How much does BMW charge?

This is not a difficult job to fit, probably take about an hour assuming you have a Reprom CD, torx bits and some care and commonsense. If you haven't already get yourself a copy of the Reprom manual.
The dealer would probably charge you about 1-1.5hrs by the time they setup the tank calibration aspect as well. Give them a call and get a quote.
Even if you do fit it yourself you will need to visit the dealer to recal the sender strip (probably 30mins of dealer time). Cheers
Cheers, KP

i have a 2007 K1200R sport and (I think) there was a recall on that part.

i don't remember the specifics but a few months after my purchase (about march 07) i had issues with inconsistent fuel gauge readings and my dealer in Escondido replaced the part. it might have been replaced under warranty but i don't remember.

check with your dealer regarding a recall.

good luck.

Looks like a recall is in order to force BMW to design a replacement fix. If this were a car, it would happen, no question.
