my bike: 2015 1200 S, 12k miles.

i started it up today, rode a few miles and noticed the fuel gauge went from 3/4 tank to empty, and the fuel icon was flashing yellow. i pulled over, added about 2 gallons of gas, started it up and the guage showed full, no flashing warnings. rode a few more miles and bang, empty and flashing again. i rode about 100 miles like that, with the gauge randomly(?) switching from a an accurate read, to the empty/warning status.

is this the typical behavior of the bad fuel sending unit issues i've been hearing about? i purchased the bike used, out of warranty, so i'm assuming this'll cost me a couple hundred, unless i attempt to fix myself. is there an easy way to tell what version of the sending unit i currently have?

Mine just failed outright. Twice. One day it worked, the next day it didn't. All the data that is connected to fuel use (range, MPG, etc) was unavailable and (if I recall) the gauge went to empty once and stayed on "half tank" the other time. However, I believe various sensors/bikes may exhibit different failure modes although most people report that they just stop working. Give your bike a few rides to see if it fails completely. It probably will. The gauge cluster can fail too but if it's just the fuel related readings, you can be pretty sure it's the sensor.

My 2016 with similar miles is having these symptoms now. Sometimes appears to be reading correctly and then the whole gauge and low fuel light alternately flashing. Has been doing this off and on for the last 4-5 fill-ups. Now just resetting the mileage odometer and filling up at approximately 160 miles each tank. Warranty had ended shortly before these symptoms and I haven't looked into replacement yet.

Hi guys, your choice. Replacement plus labor cost $300+ (chances of failing again: yes) or get a fuel bypass from fleebay for 20 something dollars and be done. I have one on my wife's Diavel and my Multi...bam.

if you do the fuel bypass, you lose the dash info yes? i understand the frustration, but i need to know how much gas i have. these days, i forget my name if someone doesn't remind me. attempting to note the milage at every fillup is not going to end well for me ;)

can anyone tell me how to identify which version sender i currently have?

Dear Dr.Jones, if you forget your name from time to time you have no business operating on the sensor, you will end up with a malpractice, the sentence for that is, learning how to use your trip meter! :)

I had this problem also. I bought my bike about 2 months ago ('16 Multi with 6500 miles on the odometer). Most times, the display would show that I had no fuel and occasionally, it would show that I had a full tank. This was regardless of how much fuel was actually in the tank. I live a few hours from a dealer and their backlog is 6 to 8 weeks so my plan is to drop off my bike once it gets too cold to ride. In the meantime, I have found that the issue hasn't surfaced since I have been allowing my bike to idle down after starting it up. I don't know if doing this is related to the fuel indicating issue not occurring lately. I can say that I have not had to deal with it since. Just FYI.

...or get it replaced, which is what i'll do. i like to know my fuel economy, remaining miles, etc.. noting the milage every time i fill up, and then remembering across multiple rides just isn't practical (for me).

also, my understanding is that the sender unit has a warranty of 2 years(?) on it. so if it fails again within that time at least the parts will be covered. i'll be calling my shop this week to confirm that, and set up an appointment.

thank you! i'll definitely try the same and report my findings.

update - called the shop today, will pop up there in the next couple weeks to replace. as i'm the 2nd owner, there's no warranty on parts or labor - both of which the service mgr said were sometimes covered by ducati for the original owner. so, i'll be out $300+ for this fix. i just realized i should have also asked about the warranty on the replacement sender once it's installed. i would expect 1-2 years for that coverage (parts only).

and if the shop can't fit me in soon, i may do this task myself. it doesn't look too difficult, just the usual on-off of the plastics with 1000 associated fasteners, and lifting the tank up - emptying the gas as well.

btw, i found this Technical Service Bulletin SRV-TSB-16-001 - it notes that you can see the version number of the sender from the wire label - no need to remove the sender from the tank. turns out i have 59210211D.

Dr. Jones, before you operate, please check with the surgeon general to see if you need to upgrade you software. My Diavel when they replaced the sensor the software got upgraded too, why I don't know. Enjoy.

I still find it hard to believe that after FOUR versions of the sender, that they still cannot get them to work. WFT ??? I have a 2001 ST2, and a 2003 ST4s, and both of those senders work flawlessly. Again, WTF ???

I ran out of fuel on my 2013 MTS GT this past Sunday, 'cuz of that f'in sender! I forgot to toggle to trip A to see how many moles were on the tank. Turns out I got 245 miles when it ran dry. Luckily my 30 oz MSR bottle got me to the closest fuel station... But 30 oz is only about 10 miles...

Happening to me also (2014 1200S, 3500mi). Sometimes when I turn the bike on I receive a "fuel sensor error" message and the yellow blinking light, no measurements of the gas level in the tank and no readings on the autonomy. Normally while riding that error code disappears (along with the yellow blinking light) and the autonomy displays "some" information. I don't trust the tank readings, as they oscillate.

Thought about replacing it but, since I'm out of warranty and knowing it would likely happen again sooner or later, will just keep track of it using my trip meter (I use meter A for it, meter B for total trip when I'm on a longer one).

These are amazing machines in all aspects, but remember guys: you can a take Ducati out of Italy, but never Italy out of a Ducati.

"remember guys: you can a take Ducati out of Italy, but never Italy out of a Ducati. "

That's a great quote!

And I stand corrected, summore reading and I see there are SIX revisions of this POS. Up to Rev F now...

I got the same on my Multi 950 2017 with 11k miles on it. It gets progressibly worst until the yellow blinking is on all the time. My dealer replaced it under extended warranty, but I saw the price they charged for it was around $250 including work.

Coincidentally, today my 2015 with 1432 miles was ridden to the dealer suffering with the same malady.....upon startup low fuel light would flash, gauge showed empty and "distance to empty" on info menu showed only a series of ….. Sadly after riding 55 miles to the dealer the goofy thing started to function properly!!! The dealer is aware of the existing issue and explained that the use of alcohol based fuel causes an issue with the internals of the sensor. In my example only 6 gallons of alcohol fuel over the course of 1432 miles have been used. I try to avoid that stuff when possible. Fortunately I am under warranty, but it is somewhat frustrating. However, before anyone starts piling on with the "Italian bike lack of reliability" parade let me inject that ALL of the last 5 new BMWs I've owned have had much worse so go figure. Whatever happened to those simpler days of yesteryear when we all did without so many of the problematic electronic doodads ( did I really just use that word? Geeze I am getting old!!) causing us intestinal grief today. By the way, my bikes out of service for 7 to 10 days waiting for "factory directions". I'll follow up in 10 days or so.

In never had problems with my 748, 749, 1098, 1198 why because they had no fuel gauges, just the trip mileage counter! Since I got my Multi and Diavel and on both these fuel sensors flacking out I went back to basics since that Ducati engineer that designed the systrm is a janitor no an electronics engineer . So instead of bitching, I got them ebay bypass connector and my ulcers don't bother me no mo 😁

hi enrico,

What’s the function of that bypass? Easy to install or a tank disassembly is necessary?

What keeps me wondering is why they continue to use those same parts/materials that are affected by fuel with ethanol,especially as several countries in the world now have that as standard (unfortunately).

cheers
