Sorry to hear of your weight indication fault.
Its a little known feature on the Ducati of the oil light doubling as a "one at a time" sensor for portly chaps!!!!
You squashed her last week at Brands and caused her to cry oil, she feels that you've not really been listening to her and has to show you in another way that "you ate all the pies"
Or get a big hammer out and give that light a clout - you'll get no problems with her after that!!!!!
p.s. - Be good to yourself!!
