To remove sensor usually requires smashing the sensor out and cleaning the sensor hole as they seize into hub carrier

The ABS sensor on the 307 is a standard type, secured by a single allen key bolt. It is located on top of the hub unit. Remove the bolt and carefully ease it out of its hole (replacement is reversal). Trace its cable back to its connection just through the inner wing.
The system will reset itself the first time you drive the car and brake sharply.
