Electronics » Fuel Gauge Readout

Started the bike (2016 RS) today and noticed my fuel gauge was not registering on the digital dash. Just filled up so I have a full tank and the gauge was working when I turned the bike off. Range mileage is functioning on dash and on Nav V. Thoughts?

Sender unit in tank

Thanks for the reply. Anyone have any experience with replacing the sending unit? Of course my warranty expired in August!

If it was the sender unit, then the ECU would not know what range you have, surely? I mean, it must know the tank level to calculate your range?

I'd try disconnecting the battery for 5 minutes and see if a "cold reset" of the whole system does the trick. Failing that, I'd be rattling the doors of the dealer; stuff shouldn't start dying 1 or 2 months after the warranty expires...

Cheers

Hi Paul,
I too wondered how the mileage readout was operating if the sensor was bad. The other day when I filled up I noticed the fuel gauge didn't respond as quickly as normal. It finally jumped up to full a couple hundred yards down the road. I'm going to take a short ride as soon as it warms up a bit and see if it comes back to life. I checked for fault codes with my Motoscan setup and there were none. I'll do a cold reset as you suggested and see where that takes me. Many thanks for your input.

This problem started right after I fueled up. I always fill the bike on the centerstand and I remembered that I nearly overfilled it due to a sticky fuel nozzle handle. In giving it some thought, I decided to see if maybe burning off some fuel might allow the float arm move a bit and bring my gauge back to life. Sure enough, within about 10 miles the display bar started to register (full) again. I ended up riding about 125 mi. and the gauge functioned as it should. I'm cautiously optimistic, but I will sleep better tonight!

Checked my bike yesterday and , bloody hell , no fuel gauge , So I checked the forum and immediately found your post. I filled up last week and only rode 8 miles home and put the bike to bed . I will take it out when the weather improves and see if my gauge resets as well , fingers crossed . Anyone else had this ?

As it's still wet and cold , and the fuel gauge is bugging me , I was going to syphon a bit of fuel out and see if that helped. First off I visually checked the level , gave the bars a good shake to make the fuel move . It was just on the bottom of the filler neck tube. Then I turned on the ignition just to see , and - - - - - - the fuel gauge works . Maybe the float was stuck and the shaking un stuck it. I don't know and I'm none the wiser . I will ride it later and make sure all is OK . I'll keep you informed.

Great news! Thanks for the update

Another quick update for anyone still following . Went for a ride today , fuel gauge read full immediately the ignition came on , all good . About a mile from my house is a rail crossing and I noticed that as I bumped over the crossing the gauge momentarily gave up and then came back on. Fuel slopping about maybe ? After that there was no more trouble . The gauge dropped one bar after 32 miles , meaning I had ridden 40 miles since filling up . So my questions are , how many miles do people get before the gauge drops one bar , and is a gauge that won't work when the tank is slightly overfilled a fault , or Mr BMW telling me I overfilled ? (sounds unlikely ).

I think as long as your gauge continues to drop that's a good sign. I let mine drop till it was about 3/4 down and filled back up again. This time I left the bike on the sidestand when fueling and when I turned the ignition back on it responded almost immediately. Burned about another 1/4 tank and all seems back to normal. I will also say a short prayer from here on whenever I pop open the gas cap!

I'm reviving this old thread as I am having a similar issue. My fuel gauge has always been slow to respond after a fill up, I bought the bike used. I just thought it was a quirk of the bike. Usually after 5-15 minutes of riding after filling up the fuel gauge would respond and go to full. My last 2 fill ups, had this same delay, but the fuel gauge never read full, but 3/5ths (the tank was definitely full). The fuel range read as if the tank was at 3/5ths, but as I rode the fuel gauge moved up to maybe 3/4 and the fuel range increased similarly. I suspect the float, but would love other suggestions. After reading this thread, I plan to do the cold reset this weekend, and will update. Thanks for the advice.

Hope the reset works, I’d find the under- reading really annoying, far more so than the slow reaction to a fill-up.
