DQS repeated problems

This DQS issue is starting to get dangerous. I had some errors with my DQS and finally it crapped out a couple weeks ago. Voltage shows in spec, no error codes, but wouldn't work at all. Finally got a new DQS put in last weekend and went for a quick short ride. It works. Great. This morning I was going to go for a ride. As soon as I got out onto the street, at decel it would start chugging. The higher rpm I was at, the more violent the chugging. It felt like the DQS was thinking I was going to shift when I wasn't (toe was on the peg, nowhere close to the shift rod), and was cutting throttle in and out repeatedly. Then it showed DQS error. Stopped on the side and shut it off for 5 min and error went away. Started riding again and it chugged again on decel. Got so violent to a point where it almost threw me off the bike because I wasn't expecting it, and the bike shut off (I was going about 40km/h in second gear). Turned DQS off and rode perfectly fine, and took it to the dealer again. My tech sent the logs to ducati to see what they say. Luckily I wasn't going fast in a corner or worst yet, doing so in front of a truck. This is frustrating when you can't trust your bike fully, especially a bike this powerful and capable. Hope this gets resolved soon as I know many people are having DQS issues.

Jeez, I went through two quick shifters on my 899 and two more on my 1199 all under warranty. This seems to be a recurring issue. I've never experienced the symptoms you're describing though, they just stopped working and I'd have to ride old school. Is this a widespread issue on the V4? Sounds like a crash waiting to happen. I'm turning mine off when I'm riding harder if this is something that's not isolated.

The only quickshifting issue I've had has been pulling out onto the main straight of the track. Whacking open the throttle and bombing down the straight, sometimes the shifter is resistant. I'll push to shift up and it simply won't allow me, requiring another try wherein it will typically work. I'm not sure if it just doesn't let me because it doesn't see a good time to let it happen or what, but it's only at WOT and not an every time thing.

Mine has been running fine for 1600 street miles, but I had a bad mis-shift in COTA going from 2nd to 1st this past weekend. I think first it just lost track of a gear displaying "-".

When I hit it again it went into Neutral, then I shifted it down 3rd time, it went into 1st with the big bang - not pleasant at all. After that, it was running OK, but I found upshift from 1st to 2nd a bit rough at WOT, should be the other way around - the higher RPM the smoother they usually are. But 1-2 was like getting a kick up your ass.. Shifting down was fine, but that violent false neutral early on made me avoid 1st gear a lot of times..

Overall this V4 quick shifter is probably the best I had, but maybe need to start looking into MotoGP pattern, if that makes it any better..

Friend of mine had the same problem on track. QS kept cutting power all the time. Turned out that one of the ballbearings was stuck and the QS would not properly return to its neutral position. Check if the ballbearings are free and replace them if necessary.

I ran mine hard through two full days @ COTA and it was buttery smooth the whole time (up or down).

I run GP shift and have Lightech rearsets mounted. Honestly, the best QS I've ever used. Waaay better than the 1299.

I see you did not use 1st, I am glad to see that it is not that necessary when you are at pace with no one impeding. Mine worked like a charm too 2 and up.

I'm having exactly the same problems, I have stock rearsets.
It started when the bike had more or less 680 km. I wonder if somebody is experiencing the same issues with non stock rearsets. Maybe the problem is something mechanical playing up with the DQS load cell (sensor)?

Update:

As my second quickshifter broke down just a few days after replacement, my tech was communicating with Ducati to make sure it's not my bike, and it's the quickshifter. They installed my old "broken" quickshifter on another bike in the showroom and it didn't work either. So now Ducati told my tech to replace my quickshifter under warranty (again). This will be my third and hopefully 3 times' a charm.
