Bentley Electric Tailgate Actuator Malfunctioning? Diagnostics and Restorations
An electric tailgate actuator is a sophisticated mechanism comprising electric motors, sensors, wiring and control modules that help in the perfect functioning of the tailgate. But unlike any mechanical and electronic system there might be malfunctions in the actuator.
As a result, your tailgate may fail to open, may stop working halfway, may close unexpectedly or show some text on the dashboard.
Function of the Electric Tailgate Actuator
The system responsible for the operation of your Bentley's rear door is the electric tailgate actuator. It controls the lifting mechanism effectively and works together with several electronic units.
After opening the tailgate the signals will be delivered to the actuator from the vehicle control unit and the actuator will perform a number of operations simultaneously with the tailgate. Unlocks the latch, operates the lifting mechanisms, controls the position of the door and ensures its tight closure.
It also serves as an integral component of the safety system that prevents the tailgate from being closed when there is something in its path.
Symptoms Indicating Failure of Your Bentley's Tailgate Actuator
Small signs can sometimes occur weeks or months before the eventual failure.
These are some of the symptoms to look for:
Your tailgate will not open or close automatically.
Your tailgate stops midway during its operation.
Noise during opening.
Opening occurs slowly.
Continued instrument panel warnings.
Tailgate reverses itself suddenly.
Closing becomes difficult.
Cannot unlock your tailgate via the remote key fob.
Why do Bentley Electric Tailgate Actuators malfunction?
Mechanical Wear
Opening and closing of the tailgate lead to gear and motor wear after each use. Due to this mechanical wear the efficiency of the internal mechanisms decreases after thousands of operations. Plastic gears become worn; lubrication becomes exhausted or moving mechanisms become loose and this leads to inefficient operation.
Electrical Issues
Modern Bentleys use electricity for communication quite often. Poor connections, blown fuse boxes, corrosion of the connections or bad electrical ground prevent the power from reaching the actuator. In most cases the wiring gets damaged and the actuator cannot get the command even though it works well.
Moisture Infiltration
Water is one of the major problems for electrical devices. If there is any damage to the connectors or actuator parts then water infiltration is likely to occur and corrosion starts to develop inside the tailgate assembly. After some time due to corrosion electrical resistance increases leading to the system failure.
Sensors Failing
A number of sensors such as position sensors and obstacle sensors are incorporated in the electric tailgate. Failure of any of these sensors to send false information to the module might make an actuator cease working for safety purposes.
Power Tailgate Module Malfunctions
The module is responsible for controlling each and every part of the functioning of the tailgate. Despite the good working condition of the mechanical parts, a software fault or miscommunication and electronic failure of the module can hinder the functioning of the actuator.
Bentley Tailgate Actuator Restoration Solutions
Wiring Repairs
Sometimes, if the wires or connections are damaged or corroded then the issue could be fixed by repairing the wiring harness.
Sensor Replacement
Insufficient position sensors or obstacle sensors can always be substituted without the need for actuator replacement.
Software Updates
Sometimes the communication between the control unit and the tailgate operation system can be improved with Bentley software updates. Car software updates might also be helpful in dealing with software malfunctions.
Latch Mechanism Repairs
Cleaning, lubricating or replacing the latch could make them operate better if the latch is worn out or covered with dust.
Complete Actuator Replacement
If the balance arm actuator motor, gears or other parts inside are damaged and cannot be repaired then the best option would be to substitute the actuator. Proper installation ensures the proper calibration and synchronization of the actuator with the car's electronic system.
Can You Prevent Tailgate Actuator Failure?
It would be possible to significantly prolong the life of the actuator but it is impossible to get rid of it entirely.
The following precautionary measures may be taken:
Prevent the litter from accumulating on your tailgate.
Never force the tailgates.
Change the weather seals regularly.
Make sure that the channels are clear for water drainage.
If there is an alert then react to it promptly.
Arrange for the check-up during your regular maintenance procedures.
