DDWB2021 Paddle shifter (27 & 28) activates on its own

As the title reads my DDWB and GT1 rim got delivered 3 days ago with the problem of the shifters activating themselves. The wheel is completely unusable since you cant choose which gear to use. I’ve tried flashing older firmwares which didnt help, i tried changing the bluetooth channel and that didnt work either.

Se nés pas le firmware mais les palette qui foire, il mon dépanné avec un nouveau capteur que j’ai changé moi meme mais sa marche pas ce qui me fait penser que ces les palette qui sont mal fait et donc par ce cas ces de la merde

cześć nie wiem czy aktualne ale udało mi się rozwiązać podobny problem na c12
problem polega na tym że czujnik od zmiany biegów jest optyczny i trzeba go wyregulować mechanicznie albo programowo
w moim przypadku wyregulowałem go mechanicznie
miej wspaniały dzień

Hi, I don’t know if this is current, but I managed to solve a similar problem on my C12.
The problem is that the gear shift sensor is optical and needs to be adjusted mechanically or software-based.
In my case, I adjusted it mechanically.
Have a great day.

Did you manage to solve this problem? Because I have the same one and unfortunately nothing works

cześć Mateusz wiem w czym problem,
jeśli chcesz mogę tobie wytłumaczyć jak to naprawić

Hi - My steering wheel is well used… I’m surprised is happening with a brand new wheel. I found that a little contact cleaner sprayed within the shifters works well… spray some both sides of the paddle and move it and activate it a few times… If it still happens, then spray some more in and repeat. I always then turn the steering wheel so that the paddle I’ve just sprayed is pointing down to drain any excess fluid. This seems to work.

Hi Toldik.
I just received my brand new gt1 wheel and downshift stays active if I push I from the upper side of the paddle.

Tell me more about your solution please I don’t understand the electronic vs mechanic part maybe it’s bad translation ?

In Cammus software 27 stays light on

Edit : For now it’s solved, i just unplugged the steering from the ddwb base and plugged it again

THIS IS WHAT MY SOLUTION LOOKS LIKE
THE PRINCIPLE OF OPERATION OF THE CONTROLS IS THE SAME IN BOTH CASES
(TESTED WITH A CONNECTED OSCILLOSCOPE)

Thank you for answering.
The issue came back a few days, I just disconnect and reconnect the gt1 wheel but it’s annoying.

So I am going to do your repair.

I just don’t understand the words “M3 pads” in English ? Is it like something like spacers ?

Each 3mm increase requires replacing the screw
