So I had a problem with my gear position indicator which might be of interest to people now or in the future if anyone gets similar.....
At first I noted that when in 4th, the indicator would show different random gears. Then later on in the same long ride, it started showing random numbers when in all the gears. Then a bit later on still, it started occasionally showing "blank" and the neutral night occasionally came on when cruising along in gear. Eventually, as I was almost home, the engine warning light came on.
The bike ran fine during all of this.
I took it back to Ducati (Cambridge) and they pre-ordered a new sensor to be fitted. After two days delay, they finally gave it back to me, all fixed. He said all they did was change the sensor and the delay was clearing the computer fault codes. I got no paperwork but wasn't going to push them on it since they did it all free of charge "under warranty" (even though I'm out of warranty by 2 months: I'm still not sure if this was kindness or incompetence on their part).
Anyway, I'd be interested to hear if anyone comes across similar!? All seems well with the fix so far.
