Passat ABS/ESP Error: 2002 Model Troubleshooting

Hello everyone.
I hope you can help me.
I read the ABS control unit using VAG Com on a Passat from 2002 and cleared the error code "Implausible signal from the longitudinal acceleration sensor."
I then, unfortunately, went to the "Adoption" section and clicked "Read" on Canal 00 (only "Read" and not "Save").
Currently, the ABS warning light is always on, and the error log shows "System diagnosis active." It can be cleared, but it keeps reappearing.
Does anyone have any idea what's going on, or how to re-enable the system diagnostics?
I would be grateful for any help!

After a longer test drive, the lights turned off on their own.
