Logitech G29 calibrates by turning hard left (-450°) on startup but is

Hello everyone,

I'm having an issue with my Logitech G29 (approximately 5 years old).

When I power it on, it does not perform the normal startup calibration (left → right → center). Instead, it immediately turns hard to the left (approximately -450°) and stops.

Here is what I have already tested:

• The wheel is detected correctly in Windows (joy.cpl).
• The wheel is detected correctly in Logitech G HUB.
• The steering axis is centered correctly (50%) when the wheel is physically centered.
• All buttons work normally.
• I tested it on both PC (Forza Horizon) and PS4 (Gran Turismo 7), and the same issue occurs.
• I tried different USB ports and different power outlets.
• I reinstalled G HUB.
• I downgraded G HUB to the March 2021 version and also tested the latest version.
• The firmware is up to date.
• The issue remains exactly the same.

There is no visible physical damage to the wheel.

Could this be caused by a faulty encoder wheel/position sensor, the force feedback motor, or the main PCB?

Has anyone experienced the same issue and successfully repaired it?

Thank you!
