Twin-opening tailgate mechanism faults
Attaches to 3T at chassis level · Body & corrosion · carried by 8 variants across 2 chassis
Overview
Twin-opening tailgate mechanism faults is a occasional fault recorded against 3T at chassis level, typically from 100–200k km. It shows up as the tailgate refusing to switch between hatch and boot modes, sticking in one mode, or a rattle from the mechanism. Where it's documented, the repair runs €200–€600 (linkage or actuator at an independent, costs dated 2026-07), and it can be checked before you buy. 8 variants across 2 chassis in this database inherit it.
What happens
Symptom. The tailgate refusing to switch between hatch and boot modes, sticking in one mode, or a rattle from the mechanism.
Cause. The twin-opening tailgate carries a mechanism no other car in the group has, and its linkage and actuator wear. It's a nuisance rather than a serious fault, though parts are specific to this car.
How to check it
Static checks
Open the tailgate in both modes several times, listening for the mechanism switching cleanly, and check the boot seal for damp.
Engine off, ideally on a lift.

The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
