Jaguar XJ sensor signal beeps in reverse due to pushed-in rear button on Jaguar XJ

Some Jaguar XJ owners report experiencing continuous beeping from the rear parking sensor when in reverse, which may indicate sensor or system malfunctions. This issue can often arise if the rear parking sensor system needs to reset, particularly in X-350 models. Additionally, dirty or damaged sensors can interfere with their operation, leading to unexpected alerts. Owners have found that cleaning the sensors can help improve their functionality. Furthermore, even minor physical damage to the bumper can affect sensor performance, especially if the mountings have been pushed in after a collision. Electrical issues, such as irregular currents affecting the sensors, can also cause beeping when the vehicle is not in reverse. To troubleshoot this problem, owners are advised to reset the system, clean the sensors, inspect for physical damage, and consider installing a Single By-Pass Circuit Relay to mitigate electrical anomalies.
