Audi A2 - rear door lock replacement – EP7 – project youngtimer

In this video I will tackle the problem with the rear left door that did not lock. I suspected that the rear door locking mechanism failed, but the problem was in the rear door control module.
Please join me and watch the complete process of removing interior door trim, aluminium door plate and door locking mechanism as well as finding the real problem, solving it and installing everything back.
At the end there is also a special part of the video intended for nerds in which I show how the locking mechanism works.
