Stuck middle rear seat safety belts are a common VW problem.
Many videos show how to solve the problem on two part VW seats, but the VW Tiguan has a one part seat, meaning the top and bottom can't be easily separated without dismantling the whole seat.
This took me half a day to figure out, because there is no access to the inside of the seat to get to the inertia reel.
Hopefully this can help those battling with this problem without having to cut the belt, or take their car to the dealership.
