DQS repeated problems

Or maybe I can ask the dealer not to update the software out of the crate for the time being?

Ducati Corporate probably does not permit that. I bet soon as its un-crated and prepped to start, they do the updates. Audi and Porsche are known to do OEM "updates" on cars when their customers specially tell them not to...soon as its hooked to the computer, it checks the date and sees if an update is ready....and in it goes.

So is this happening to everyone now?

I'm meant to drop off my 1299 tomorrow and pick up the V4 Monday. Seriously considering not doing that now. Or maybe I can ask the dealer not to update the software out of the crate for the time being?

I have 3300 miles on mine now and have not encountered any DQS errors. Got a few tiny ones before the 600 mile service, but those were solved with simple off/on cycles.

Just got my ecu update for DQS. Maybe it's different as it detected my upmap and the wording for the update says it's for full exhaust maps only.

Did a few WOT runs... No change in power that's noticeable. No change in any of the controls like EBC, DWC, etc that I could notice. Power delivery the same. Just the DQS is more sentitve and a lot faster. Doesn't backfire as much as before because it gets into gear so quickly. And it seems to be throttle based... The more throttle during up shift, the quicker the shift. Downshift feels the same except slightly more sensitive.

Let's hope this is the update that will last! Thanks for the update.

dqs

so took my bike back in the plugged in the computer checked over all maps and such no changes . then the reset the gear selector and the bike is back to normal power . with the qs update it is smoother and softer like a damn marshmallow i like it better when i was more violent

I had the same issue but not light, just cut out then back on it happened about 5 times on two separate days. I took it back to the dealer they reset the Ecu and did the Qs update I ended up having a faulty Qs so they replaced it and I haven't had any issues since but I've only rode it about 25 miles since I got it back from the dealer last week

Question for you guys: Did anyone with the QS issue have their TC/ABS light come on when the power was getting cut? Just yesterday I was at about 90% throttle in 1st going on to the highway at a fairly spirited speed. The front wheel was off the ground (as it does when you give it the beans in first) and then the damn thing cut to what seemed like 0% throttle, front smashed down, smashed my balls on the gas tank, etc. I hadn't had a chance to roll off the throttle given the major WTF moment and it immediately surged back to full throttle again (about 2 seconds after cutting out). One thing I did notice was the amber TC/ABS light flashing when this happened.

I was riding with warm tires on scorching hot smooth asphalt, off the brakes, not cornering, lots of traction - no reason for any type of interdiction to be happening - so the TC light flashing was a bit of a mystery.

Is this consistent with what those of you that have had the QS issues experienced? I left mine on but turned around and rode back home at a very relaxed pace. Didn't notice any issues other than the one occurrence and no weird chugging before or after. Other than that one occurrence the QS has been great, but now I'm scared to ride this thing hard and need to figure out what to tell the dealership. If anyone can confirm / deny that this is similar to what they went through that'd be great. Might be something else but I can't see what other system would completely chop the throttle like that for such an extended period of time.

Hi - I'm new to the V4 forum! Wanted to check with you guys some similarities with the issue.
_________

Took my V4 to the track for a Sunday stroll after getting it back from the dealers after two weeks to sort EM light issue – some debris got stuck in the exhaust flapper valve!!!

Anyway, after about 10 minutes into the first session, the bike behaved strangely on corner entry – jerking and shunting forward when the throttle was fully closed and even though braking. The quickshifter stopped working intermittently, but came back eventually.

Feeling almost like the auto-blip is out of sync, with the down-shift being quite harsh, I re-calibrated the tyres to see if this would make any difference.

Next session was fine for 1 lap, and then same thing – a shuddering shunt into the corner – and again - no quickshifter this time for the whole session. Also, at the settings menu in the right bottom corner, an error would be displayed in red next to the DQS option.

I then unplugged and re-plugged QS connector a few times, disconnected battery to reset ECU, changed tyres and re-calibrated again, but the problem would re-occur within the first lap, only disappearing upon ignition switched off for a few minutes and switched on again.

I ended up riding old-school using the clutch the rest of the day.

Bike is in for repair now, and the dealer says it is the second one for them.

I have noted some trends regarding the issue and wanted to confirm with you guys but it seems like the issue started after software update and effects mostly bikes built in February.

Your feedback is appreciated

Astute observation about build date being related to the QS problem. I'm eager to see if you're right.

I dunno. I have the first V4 base to make it to the west coast and I haven't had any quickshifter issues, even after a few track sessions and 3500 miles. I cross my fingers every time I say that though.

Just got a text that the bike is ready for collection - no diagnosis report or explanation. Let's hold thumbs

I was following someone on FB that had the same problem and this was his fix below. My bike will be going to service tomorrow for the same issue and if i get the run around (cant replicate blah blah), im going to install a QS from a super sport as the part# are the same but supersport end with a B and the V4 end with a C. I was able to locate a use one off ebay for 100.




"Well ducati took the bike and ran some dyno tests but could not replicate the issue, at the same time ducati released an ecu update that included a dqs update which they did as well as just replacing the qs itself. I rode the bike some more and still had qs lockout on upshift but this time it felt mechanical not like before where it felt more like a drunk ecu.
Again back to ducati.. Again they replaced the quikshifter but this time used an older batch qs from I think a supersport model (runs the same qs).
Bike now preforms smooth as a whistle with zero issues and trust me when I say I put her to the test!
Maybe a faulty batch of quickshifters?? Seems the older batch qs works no worries."

Some feedback guys.

Ducati replaced my DQS - They say diagnosis showed "DQS circuit open/close" error and they just replaced it. No questions. Taking it out this weekend. Wooop!!!

This is worrying however!

The first thing to look at is going to be the him joint that attaches to the shift lever, about half of the quick shifter issues we have seen has been from there being too much loctite applied at the factory (it gets into the heim joint and acts as a sleeve retainer)and it causes the shift lever to bind in the direction of the last shift. There is an issue and Ducati is working diligently to remedy it. The part numbers for the Supersport QS and the V4 QS are different, but are essentially the same part, I have not tried this repair yet, but will this week and I'll report back here for everyone.

I'm not sure how diligently they're working on the issue. Across three Panigales ranging from 2012 to now, I've required FIVE new quick shifters. It's a pressure switch, not a space shuttle. I'm guessing it's not bad enough for business to actually find someone to make these things out of metal and up to higher quality standards. I dissected one that the plastic housing deformed on my 899 and it's absolute trash compared to aftermarket units I've added to other bikes. As soon as I find a good aftermarket switch that I can make work with my V4, that OEM piece of crap is gone. I've been waiting on Ducati for six years to address these things, I'm not holding my breath at this point.

Some goes for the mirrors/thermostat housing etc.... all about selling as many oem parts as possible.

Feedback: Got the bike back and took it out for a spin. Seems fine, but I'll only really know once I take it through its paces on the track.

Interestingly though, the part number of the replacement QS is different than the one that was originally fitted on the bike - although it is still V4. Perhaps Ducati has attempted to fix the issue.

I'm facing the same issue now after 1700 km. Out of interest can you share the part number of the replacement QS please?

Bumping this thread as opposed to starting a new one.

My DQS system hasn't been working for the last two months or so and it has been in and out of the dealer for them to remedy. I have the CNC Pramac rear sets installed and switched to a GP shift pattern. I have attempted to toggle DQS on/off and switch through the various riding modes and the QS doesn't work in either up or down. The dealer recently had the bike for 5 weeks and installed a new OEM QS and it did not solve the issue. They said they need to do a U-tech session with Ducati in an effort to figure it out.

After reading through various threads online it sounds like some have experienced failed sensors by themselves. Others have experienced gear position sensors failing due to excessive heat which in turn effects the QS. Mine never works whether the bike is cool or hot. Is there something in the firmware that could be corrupt? Any ideas are appreciated. Thank you.
