(First post here, sorry for formatting issues) 2015 1299S, stock quickshifter isn't functioning correctly. Usually won't work at all (Rarely works on the downshift, never on the upshift), and after a short while riding the bike (No specific length of time), the CEL will come on (sometimes it never comes on, or comes on instantly). I haven't had a chance to scan the code yet since it resets the instant the bike goes off and I'm forgetful as hell.

For context, the bike was set down twice last year, once when I was run off the road by an ever-so-loving mother of 3 in a Toyota Sienna, and the second when the asphalt at work melted enough to let the bike down rather hard. I got it repaired at the local-ish dealer both times, the second time having them install a RapidBike Evo module while they were messing around with it. Problem started shortly after that. Did the repeated impacts finally do the part in or does it seem like a electronic issue? Just don't want to buy any unnecessary parts, especially when they're 400 bucks a pop. Any help appreciated!
 
I purchased a the HM OEM replacement quickshifter. Expecting to to be far better than the factory DQS hardware

Mines never been down like that, crazy! But the quicshifter is intermittent and makes me look like an ....... sometimes so it’s getting replaced
 
Parts guy over at the dealer told me they were a problem part in the past, so might just get a new one and be done with it... but would really prefer to pinpoint the issue first. Any diagnostic tests to check these strain gauges or are they just usually fixed by the almighty parts cannon?
 
Good we can compare. I’ve got the OEM replacement quickshifter coming from HM sometime soon
 
I thought about the HM unit, decided on the TL based off reviews, sounded like fairly similar performance between the two, and for the price (about 100 USD below cost of an OEM sensor) I can't complain. Here's hoping it gets my DQS to finally work
 
Cheers brother!

Ducati OEM Replacement Blipper Shifter | HM Quickshifter

The quickshifter/blipper sensor supplied as standard on the latest model motorcycles are a simple switch with a spring. This part has already shown to be unreliable and lacks feel for positive upshifts and downshifts. Using advanced strain gauge technology, our sensor fixes the issues...

The stock QS is a microswitch. Is the HM OEM replacement a microswitch as well or did they configure a SG to work with the Siemens Continental ECU?
 
It’s an SG. There’s a higher level (in price too) one by HM that’s supposed to be even better but I’m sure the aftermarket SG will wipe the floor with the factory one

here’s mine

first, i don't say this is the one and only truth, it's my believe. from the point of view of a mechanical engineer.

it isn't a simple switch. in combination with the spring it is a sensor.
almost all(?) oem shift-sensors are of this type. Why?
the spring load helps to minimize or eliminate variations in your foot action.
(good for the gear box)

the ducati , OK, it may not the best, and could be replaced with a better, settable one.
but that's my estimation, i believe in mechanics.
Ask yourself: would i replace the desmodromic with pneumatic acting valves?:eek:
that was bitchy, sorry.

all valid. My 1299 has 5k miles on and it’s ready for new DQS hardware. I guess I used it so much it broke. Probably same reason I get abt 2K miles from rear tyres
I love the pops and bangs on upshift so needless to say we’re going to torture test this HM and if it sucks I’ll be sure to let you guys know.

my buddy has the HM Pro version getting installed soon, so we’ll have a report on that too. If I wasn’t informed abt HM it would have been TransLogic but it certainly wasn’t going to be another 5,000 mile limit quickshifter unit from Ducati

Maybe things were improved on the V4. but I guarantee in a few months the 2018 owners are going to have issues with air getting in their clutch action hydraulics and need to replace master and slave cylinders bc the factory equipment doesn’t withstand the test of time.

They’re manufacturing my HM unit in a sterile facility in England right now

to validate your points, I reached out to BrennTuning about the matter and they say:

“Should be fine adding the new quickshifter. Though we have found aftermarket ones to not be reliable at all. The stock ones seem to work much better in our experience.”

Would electronically controlled valves work

I’m still lost as to why the 2020 v4s arent turbocharged like all the other Audi products

What type of stuff do u mechanically engineer?
 
curiosity's like that for example.
i love it that way

(no, its not mounted, just a fitment check, if this ever happens i will report)

i've learned car mechanic when timing chains or wheels were state of the art and belts .........
and Audi made one of the best (german)cars ever.
today im happy to see a belt since the chains are flimsy .... that last not longer than belts.
so, when i say i believe in mechanics, i don't meant that:

Well, got the TransLogic unit installed. Part is brand new, install went smooth- quick shifter still doesn't work, up or down. It feels like it tries to work at lower revs on downshift, but that might be me just accidentally forcing it into gear. More ride time is needed to confirm, I'll check into it tomorrow. Guessing I'm going in and dealing with my dealer again. My new thoughts are, it's either got to be in the wiring or in a bent shift rod or something. I swear this bike just LOVES making me hemorrhage money sometimes.

But on a positive note, the new Termignoni exhaust I got on it sounds and performs phenomenally, so today's test ride wasn't all bad.

yeah but I bet after it’s all sorted out, it’ll be your favorite motorcycle ever until you get ur next Ducati haha

it shouldn’t be that bad after u get DQS sorted. Maybe a clutch slave cylinder and lots of rear tyres if ur riding it right.
Congrats on the exhaust. I’m sure you understand how spirited these bikes can be when they’re opened up

It's my favorite motorcycle by far already- leaps and bounds better than my other two wheeled wonders.

I'll post here tomorrow once I test ride it some more. Gonna try low, mid, and high rev shifts, both up and down, see what is and isn't functioning. No CEL thrown as of yet so that's a promising sign.
 
As point of interest I've done 23,000k's on mine. Thrashed it up and down the gears, stomping on it with my size 14 boots (I'm 6'4") with merciless abandon and the QS has never missed a beat. What has happened is that the stock rearset has worn and the linkages have become sloppy, a first class repair would involve machining and adding needle rollers but I elected to shim it and use thicker washers etc to tighten it up. I think in in the long term I need higher quality rearsets and a translogic unit but I cant get my head around coughing up a grand or more for the solution just yet because its still mint!

The microswitch unit is uber simple, I think if you carefully examine your linkage and remove the slop and check the springs/action in the switch itself you can probably sort it. BTW mine is setup for GP
