Authentic Original Manufacturer Part

Where is this part fitted & What does it control?

This Seat Belt Retractor mechanism is located on the Rear Left Side (NSR - Near Side Rear on UK Right-Hand Drive vehicles, or Driver's Side Rear on EU/US Left-Hand Drive vehicles). It mounts behind the C-pillar plastic trim next to the rear passenger seat. It controls the extension and secure retraction of the seatbelt webbing, locking instantly during sudden deceleration or impact to protect the occupant.

Fitment Location: Rear Left Passenger Seat, behind the C-pillar trim.

Context: Vital safety restraint system for rear passengers.

Part Details & Symptoms of Failure

Material & Construction: Manufactured with high-tensile woven nylon webbing, a heavy-duty steel mounting chassis, and a highly calibrated internal locking pendulum and pretensioner system engineered for maximum passenger safety.

Common Symptoms of a Faulty Seat Belt Retractor:

• The seatbelt is slow to retract or droops loosely over the seat.
• The belt webbing is frayed, cut, or damaged (an instant MOT / inspection failure).
• The retractor is jammed completely and will not pull out.
• The vehicle was involved in a collision, triggering the internal pretensioner (once deployed, the unit must be replaced).

The MASSIVE Benefit of Buying Original Parts vs Cheap Copies: Safety is paramount. Buying a factory original, authentic VW seat belt guarantees the locking mechanism will activate at the exact G-force intended by the manufacturer. Cheap aftermarket seat belts may fail to lock during an accident. By purchasing our thoroughly inspected, premium factory part, you ensure your passengers' safety while saving up to 70% compared to buying brand new from a main dealer!

Estimated Repair Time: 1.0 Hour

Required Tools: Plastic trim removal tools, Multi-spline/Torx socket set (M10/M12 usually required for seatbelt bolts), torque wrench.

Brief Fitting Guide: Disconnect the vehicle's negative battery terminal and wait 15 minutes to disable the airbag/pretensioner circuit. Fold down the rear left seat. Carefully unclip the C-pillar interior trim panel. Unplug the electrical connector for the pretensioner (if equipped). Unbolt the top anchor point and the heavy-duty bottom mounting bolt securing the retractor reel. Extract the old unit.
