Genuine used Land Rover lower tailgate switch / release switch suitable for selected Discovery 3 and early Discovery 4 L319 models. This switch forms part of the split-tailgate system and is used in the operation/release of the lower rear tailgate.
Part Number: FQY500011
Land Rover OE Number: FQY500011
Manufacturer: Land Rover
Part Type: Lower Tailgate Switch / Tailgate Release Switch
Position: Rear – Lower Tailgate
Vehicle Platform: L319
Application: Split Tailgate Release System
Condition: Used Genuine OEM Part
COMPATIBILITY
Suitable for selected Land Rover Discovery L319 models fitted with OE part number FQY500011.
Land Rover Discovery 3 / LR3 L319:
• Approximately 2004–2009
• 5-door SUV
• Models equipped with the factory split upper/lower tailgate
• Petrol and diesel variants where FQY500011 is fitted
Land Rover Discovery 4 / LR4 L319:
• Selected early vehicles, including approximately 2009–2010 applications where the same FQY500011 switch is fitted
• Compatibility depends on production date and original tailgate specification
Suitable for UK RHD and LHD vehicles where the same tailgate switch and connector configuration are fitted.
IMPORTANT: Discovery 3 and Discovery 4 L319 vehicles underwent component revisions during production. Please use the OE number FQY500011 as the primary compatibility reference rather than relying solely on model year.
TECHNICAL INFORMATION
The lower tailgate switch forms part of the electrical and mechanical release system used on the Discovery L319 split rear tailgate.
The Discovery uses an upper opening tailgate section together with a lower fold-down tailgate section. The switch allows the appropriate tailgate release function to be activated when the vehicle is unlocked and the required opening conditions are met.
The switch operates together with components including:
• Tailgate locking mechanisms
• Tailgate release actuator
• Upper and lower tailgate latches
• Central locking system
• Tailgate wiring harness
• Electrical connectors
• Release cables/linkages
• Vehicle body control electronics
TAILGATE SYSTEM INFORMATION
A faulty tailgate switch can prevent normal operation even when the actual latch and actuator remain serviceable.
Because several components are involved in the L319 tailgate system, correct diagnosis is recommended before replacing individual parts.
COMMON SYMPTOMS / REASONS FOR REPLACEMENT
• Lower tailgate release not responding
• Tailgate switch works intermittently
• Switch requires excessive pressure to operate
• No response when the switch is pressed
• Damaged or worn switch
• Internal electrical contact failure
• Corroded electrical terminals
• Water or moisture contamination
• Damaged connector
• Replacement following tailgate repair
IMPORTANT DIAGNOSTIC INFORMATION
Before replacing the switch, check:
• Tailgate actuator operation
• Upper and lower latch mechanisms
• Electrical supply to the switch
• Switch connector and terminals
• Wiring continuity
• Central locking operation
• Release cables/linkages
• Signs of corrosion or moisture ingress
If the switch is receiving the correct electrical supply but does not provide the expected release signal, the switch itself may be faulty.
If neither the switch nor actuator appears to operate, further investigation of the wiring, power supply and central locking system is recommended.
INSTALLATION
Designed as a direct replacement for the corresponding factory Land Rover component when OE number FQY500011 matches.
Installation generally requires access to the relevant lower-tailgate trim/components, disconnecting the electrical connector and replacing the original switch.
Ensure the connector is clean and securely fitted before completing installation.
PROGRAMMING / CODING
Programming or coding is normally not required when replacing the existing FQY500011 switch with an identical compatible component.
The replacement should operate through the vehicle’s existing tailgate and central locking system once correctly installed.
IMPORTANT COMPATIBILITY NOTE
Please match OE number:
FQY500011
with your original component before purchasing.
Also compare:
• Electrical connector
• Connector pin configuration
• Switch design
• Mounting arrangement
• Overall shape
• Production date of the vehicle
Do not purchase based solely on “Discovery 3” or “Discovery 4”, as different tailgate components and revisions can be fitted depending on production date and specification.
CONDITION
Genuine used Land Rover OEM part.
Normal signs of previous use, storage, marks or cosmetic wear may be present. Please inspect all listing photographs carefully as they show the actual condition and components supplied.
Ideal genuine replacement for a faulty, damaged or intermittent lower tailgate release switch on a compatible Land Rover Discovery 3 / early Discovery 4 L319.
