When I bought my bike , I had two, major issue but the price was right, one was overheating and the other one blinking yellow triangle and not showing the fuel , I did fix the overheating issue and I did post it , and this morning I worked on second issue the fuel strip issue , I removed all the panels , disconnected two plugs and fuel line , less then 3 min, and I removed the tank from bike, You don't need take gas out (as you can see I have half of tank gas inside nor take fuel pump side out .All I did use ohm meter , and I did read two center pins ( in 2 and 3) in 3rd photo and ohmmeter did read nothing , it was open, I did use zipper light mod and zipped couple times , that did the trick total cost well nothing but used light i had in house!!!!!!
( And here is link for light mod) https://www.instructables.com/id/Scr...hter-Teardown/
I did used ohm meter and this time it did read 2.92 K ohm,
installed everything back and worked like charm , it showed the yellow triangle for about 10 second and it was gone and now the gauge was working great , dealer wanted around $450 and again not sure even new one how long would last , BMW had 12 years warranty and mine pass warranty date, So I thought it share it everyone , total time around 3 hours and most of that was removing and installing panels !!!! see the Photos. Now the only thing is left to reset the service warning!! and for that I need GS911 , which I don't have budget right now, but wait minute, I saved $450!!!! I can afford it now
