5WC959107A Tailgate Kit Genuine OEM Power Liftgate Retrofit Set for VW Tiguan Mk2

About this part

The 5WC959107A tailgate kit is the brand new genuine OEM complete power liftgate conversion set for the Volkswagen Tiguan Mk2, supplied as the full factory parts bundle rather than a single spare part. It converts a manually operated rear lid to the electrically opened and closed power tailgate, and it is built around the 5WC 959 107 A liftgate control module – a Continental unit carrying the VW AG marking, made in China, with the H05 hardware index on the label. Every component in this set is a genuine VW AG part: two electric drive struts (the left one is stamped 5NG 827 851 D 04S), the power latch actuator (3GD 827 887B), the silver striker, the hinge pair, the control module, the interior close button, the exterior release switch, the release cable sensor with its foam sleeve, the coiled wiring harness with the warning buzzer in a sealed bag, and the connectors at both ends of the strut loom. Because the module, the two struts and the latch have to be coded and adapted as one system, buying the complete matched set is the only reliable way to retrofit or repair a power tailgate: mixing a used strut with a different module revision is the classic cause of a lid that stops halfway, reverses for no reason, or refuses to soft-close. The 5NG and 3GD numbers stamped on this set are simply the Chinese-market part numbers for the very same hardware that overseas catalogues list under the 5NA family: short-wheelbase and long-wheelbase Tiguan Mk2 cars use exactly the same struts, latch, module, switches and harness, and this complete kit is identical to and fully interchangeable with a 5NA series power tailgate kit.

tailgate kit – genuine 5WC959107A liftgate control module with the matching 5NG electric struts, 3GD power latch, switches, release sensor and full harness; 5WC959107, 5WC959107A and 5WC959107B are interchangeable module revisions of the same liftgate control unit.

What is in the set, and what each part does

The drive units. The two long electric struts replace the ordinary gas springs. Each contains a small geared motor and a spindle that pushes the lid open or pulls it shut, plus a Hall sensor so the module knows the exact position of the tailgate at every moment. One strut carries the harness pigtail with the corrugated sleeve and the multi-pin plug; on the photographed set the housing is marked 5NG 827 851 D with the VW AG warning symbols and a 29.04.24 production date. The struts are a calibrated pair – their spring stroke and motor speed are matched, which is why they must always be replaced together.

The latch, striker and hinges. The power latch actuator (3GD 827 887B on this set, with a 20260109 date code) contains the release motor and the rotary latch that pulls the last few millimetres of the lid tight against the seal. The silver striker on the body sill and the two black hinges take the load when the lid is moving. A worn latch is the usual reason for a tailgate that closes, rattles, then pops back open; a misaligned striker makes the motor work against the seal and trips the anti-pinch logic.

The electronics and the human interface. The 5WC 959 107 A control module reads the strut Hall sensors, the latch microswitches, the release cable sensor and the two switches, then drives the motors over the CAN bus with the central electrics and comfort systems. The wide interior button closes the lid from the luggage compartment, the small exterior switch releases it from outside, and the buzzer gives the audible warning while the lid is moving. The harness ties all of it together with the correct colour-coded wires, fuse tap, gateway connection and plugs – there is no cutting or soldering of the factory loom when the correct set is used.

Why a complete set instead of one part. A power tailgate is a closed loop: the module learns the travel and the closing force of the specific pair of struts fitted, and the latch has to agree with that learned position. Fit one new strut next to a tired one and the lid twists, the Hall counts disagree, and the module either faults out or interprets the extra load as an obstruction. Fit a module from a different letter revision and the connector may be identical while the coding parameter set is not. The factory solves this by supplying the conversion as a matched kit, and that is exactly what is offered here – all thirteen pieces from one production batch, photographed together.

Diagnosis, installation and coding

– Typical symptoms on a car already equipped with a power lid – the tailgate opens a few centimetres and stops, reverses on the way up, closes but springs back open, drops slowly on one side, beeps without moving, or shows “tailgate not closed” although the latch is shut. Fault memory commonly holds codes for the liftgate control module, strut Hall sensors, supply voltage, the release motor or an interrupted CAN message. A weak battery, a corroded plug at the strut pigtail or a pinched section of the D-pillar harness will imitate a dead module, so check voltage and connectors before condemning electronics.

– Before you order – read the number on the original module and on both struts. The 5NG and 3GD prefixes on the parts pictured here are the Chinese-market numbers for exactly the same components that European and other overseas catalogues list in the 5NA family. There is no long-wheelbase versus standard-wheelbase split in the hardware: the Tiguan L and Tiguan Allspace use the same struts, the same latch, the same module and the same harness as the standard Tiguan Mk2 (AD1 / AX1), and this complete set can be swapped with a 5NA series kit as a whole, with no extra brackets, adapters or different struts needed. The 5WC 959 107 A module is also fitted to 2022-2024 North American Tiguan, Atlas, GTI and Golf R applications. Compatibility is decided by the VIN and the PR codes rather than by the model year alone, so send us a photo of the original module label and both strut markings if you are unsure.

– Retrofit notes – disconnect the battery, remove the tailgate trim, the D-pillar trims and the relevant headliner edge, route the harness along the factory channels (never across the hinge pinch point), fit the hinges and struts with the ball sockets fully seated, and replace the manual latch and striker with the powered pair. Fit the two switches and the release cable sensor, connect the module and the buzzer, then restore power. The job is not finished until the module is coded with ODIS, VCDS or an equivalent tool: enable the power tailgate in the central electrics and comfort coding, perform the basic setting / adaptation of the strut end positions, teach the anti-pinch force and, where fitted, calibrate the hands-free sensor. Clear the fault memory and cycle the lid several times from the remote, the driver door, the interior button and the exterior switch before handing the car back.

– What this is not – this is a genuine OEM hardware set for converting or repairing a power tailgate on the vehicles listed below. It does not include a new tailgate shell, paint, a remote key, a hands-free kick sensor control unit or dealer labour, and it is not a universal aftermarket kit. Coding and adaptation are required; without them the lid will not operate correctly. A workshop with VAG diagnostic capability should do the final commissioning.

Fitment

This matched set fits the second-generation Tiguan family built on the MQB platform – the standard-wheelbase Tiguan Mk2 (AD1 / AX1) and the long-wheelbase Tiguan Allspace / Tiguan L alike – plus the closely related SEAT Tarraco. The 5NG and 3GD numbers stamped on the components in our photos are the Chinese-market equivalents of the 5NA series numbers used in European and other overseas catalogues; the parts themselves are identical. Both wheelbase versions therefore take the same electric struts, power latch, control module, switches and wiring harness, and this complete kit interchanges with a 5NA series kit as a whole – no separate long-wheelbase version exists. Because the module, struts, latch and harness are a coded system, confirm the numbers on your original parts or give us the VIN before ordering. The table below is a guide, not a substitute for a parts-catalogue check.

Shipping and packing

The complete set is packed in one foam-lined carton with the two struts strapped separately so the ball sockets, the corrugated harness sleeve and the connector latches cannot be crushed in transit. All small parts – the switches, striker, hinges, buzzer and fixings – are bagged and labelled. Orders leave within one to two working days of cleared payment and tracking is emailed when the parcel is handed to the carrier. Customs charges, where they apply, are the buyer’s responsibility.

Condition & warranty

Brand new genuine quality 5WC959107A tailgate kit, twelve months warranty against manufacturing defects covering the components as supplied. The warranty does not cover damage from fitting struts without the required basic setting, forced operation against an obstruction, water ingress through a damaged connector, or coding and labour costs. If a component arrives faulty, send us photos and the diagnostic scan before returning anything so we can identify the affected part of the set.

Wholesale

Tiered pricing for 1 pc, 5 pcs and 20 pcs is shown below. Bodyshops and retrofit workshops should ask for a combined quote – we price mixed orders of power tailgate kits, kick sensor kits, ACC retrofit harnesses and camera kits together, and a conversion job regularly needs more than the lid hardware alone.
