DualSense Controller V4 Repair

Sony's PS5 uses DualSense controllers, featuring adaptive triggers, haptic feedback, multi-device connectivity, and USB-C charging.

Although all regular DualSense controllers use the same model number (CFI-ZCT1W), Sony often updates the controller's internals. Repair procedures vary between models.

To tell what version DualSense controller you have without disassembly, find the serial number printed on the back. It's usually 17 characters long and starts a letter, like E, F, or G. The second digit in the serial number is the version number, 1–5 correlating to V1–V5. For example, if the second digit is a 4, your controller is a V4.

Alternatively, scanning the QR code on the controller's back will return the same serial number—and the second digit is the version number. On iPhones, you may need a 3rd party QR code scanner application.

Internally, the versions correspond to motherboard models, namely BDM-010, BDM-020, BDM-030, BDM-040, and BDM-050.
