    Hello gentleman!

    First of all - sorry for the poor language. Even though I come from Polish origin on my father's side, I don't know the language, and this post was made with the help of "google translate".

    A recently purchased broken wheel exhibits the infamous calibration issue and the loss of force feedback in games. The warranty is excluded.
    Tried contacting Thrustmaster technical support but they don't offer spare parts and they insist on sending the wheel back to France which is way too expensive.

    I have searched the entire internet and this forum is the only site I found that actually offers any repair information other than "referring it to thrustmaster".

    I read a side thread https://www.elektroda.pl/rtvforum/topic3176691.html and although he has a few ideas where to look, they all work well on my wheel.

    The problem is easy to reproduce even outside of the game.
    1) Run the thrustmaster calibration tool and check that the wheel returns from both stops at the same speed
    2) Flip the wheel to one side and hold it for a few seconds - the wheel now returns to the center at a much slower pace from this side and a much greater pace from the opposite side. In other words, the calibration has already been compensated.

    My electronic knowledge doesn't go much beyond "Ohm's law", but I can solder fairly well and have a multimeter.

    * I checked the wheel thoroughly beforehand - no broken cables or burnt parts can be seen and no leaking capacitors can be seen
    * I checked the power supply - it outputs 31V which is a bit too high
    * Tried to replace the power supply with another device that outputs 25V at 3A
    * I took off the magnetic rotational position sensor assembly and checked the plastic mounting part and the plastic adapter on the motor shaft where the magnet is attached - it is firmly seated.
    * I checked that the AS5048A sensor is receiving a stable 3.3V

    I'm out of ideas. I would at least like to pinpoint which parts need to be replaced, and if they cannot be repaired by myself, I will continue the annoying supervisor support until they decide to sell me a replacement part.

    Here are some photos.

    Thank you very much!

    I was able to fix the wheel. The problem was with the wheel motor, where the magnetic core jumped out of the shaft itself.
    Many thanks to Fikszyn who described this issue in the thread https://www.elektroda.pl/rtvforum/topic3176691.html.

    Disassembling the motor was not easy, but it was manageable with the right tools. I had to use a CA to untie the motor plate from the housing while it was glued.

    I cleaned the shaft spacers and magnetic core with a solvent then applied the red loctite and allowed it to cure overnight. Once installed and running the thrustmaster calibration tool, the wheel works perfectly!

    Here is a video of the key shift under load
