What to do if the trunk of Audi A3 cannot be opened?

[StStephen]

First, release the rear seat hook from the steel plate, fold down the rear seat, and lift the fluffy cover inside the trunk, then pull it out and lay it down. Find a suitable-sized binder clip and clamp it onto the hook of the S-shaped linkage. If the binder clip is large enough, it will extend a few millimeters, which is sufficient. Once clamped, it will be very sturdy, and the trunk will open with a gentle pull.
