Fuel Gauge Issues (Too)
I ran out of gas last week with well over 1/4 indicating on the gauge. I'm using the tripometer now. What I did notice is that right now I'm a little above 1/4 tank again. My tripometer indicates that I rode 210 miles, but the onboard computer thinks I have 120 miles remaining. So, the bike thinks I can ride for about 330 miles on one tank of gas. The tank holds a total of 6.3 gallons and at about 40 miles/gallon, that figures to be 252 miles (give or take a few).
I'm not a mechanic, nor do I pretend to be one. But I believe that something in the bike's computer/CAN bus, or whatever, is suddenly not ciphering correctly. Last month I had the software updated during the annual inspection. Before that I routinely ran the bike until the low fuel light came on. It usually came on right at about 220 miles, which is what I'd expect.
Also, I called the BMW roadside assistance when I ran out of gas. The guy who came to help me out, said that he had two similar incidences on K1200's in the last month (faulty fuel indicator).
Something has changed in the past couple of months. I don't know if it is the software update or the fuel indicator sensor. Any help is appreciated. Thanks.
