I’ll add that I do not feel mine was an issue with heat. I very well could be wrong though. While I don’t recall the exact weather conditions, I know it wasn’t overly warm. S.E. Michigan and roughly about a month ago. What I do know is where and how I was riding. Casually, not aggressive and on 55-45 mph roads, pretty continuously. Unless something else was going on that I wasn’t noticing with the cooling mechanics... I wasn’t monitoring the temperature gauge.
So... I just took a ride, since the first attempt fix fail ride home (May 23rd.)
It was merely 70 degrees here (according to the S3), all seemed normal/functioning properly. Engine temperature had eventually gotten up to over 200 degrees (I think 219/21max, while sitting/ideling at an ATM) & then rode on. The low fuel warning light came on as expected (according to the bar guage) for a few plus miles and then on came all the flashing [guage empty]. When this happened, I was looking at 190 degrees. Mind you, this was still on the same tank of first fueling of the season. The same tank this initially happened on the ride to/from the dealer fix fail.
Rode on to get fuel, turned the bike off, filled up and all was OK. Rode a good 40 plus miles and all is normal/as should be(?). I did notice that I was getting a range reading of more than I’d ever seen, around 185 miles (vs. 175), but this was after already riding 20-25ish miles (after fill up). After a few plus more miles, I again looked at the range and it’d suddenly dropped down to where expected miles wise (around 150-55). Looking at the trip odometer and the range, everything again (yet finally) seemed to calculate accordingly. I continued to ride to see the bar guage start to drop and it eventullly did.
At the moment, all seems OK, but... I’m really uncertain. Could it just have needed to cycle through a full tank of properly showing the actual low fuel level and is now good after filling up?!? I don’t know.
I’ll see what the next ride brings and hopefully before going to the dealer unnecessarily (doubtful). Still waiting on an ordered new fuel level sensor.
Looking back through the thread here, the mention of the Multis... when I’d called about this issue initially, it was said they were aware of one similar sounding problem with a Diavel.
Also... I’ve been riding my recently Termignoni equipped ‘17 M821 to/from work almost as much as possible and ****... what an absolute thrill it was the ride the S3 again! Love it!!
