WARNING: This page is about a different car, the 2021 Audi S4 and 2021 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
Install in reverse order of removal and note the following:
-- Clean the threaded pin threads on the roof railing with a wire brush.
-- Check the seal for damage.
-- Carefully remove any remaining locking fluid from the nut threads that are installed with locking fluid using a thread tap. Otherwise the threaded pins could lock up when installed and break off when removed again.
-- Insert the roof railing with the alignment pin into the mount on the vehicle roof.
-- Install the nuts with locking fluid and tighten.
