Hi, I own a 2018 1.4 Superb SEL Exec (UK). Recently I started to have a problem with the rear passenger side door lock (which seems to be quite common). The auto lock would fail to engage during driving and when locked by the key all doors except that one locked while the passenger remained open. Recently it got more temperamental and it can only be open from the outside after the inside handle being pulled. Hopefully that is just an actuator that needs to be replaced. Does anyone know the exact part number that I need to order to replace it? I saw videos for taking the door trim off and that should be fine,are there any particular tools that I will need to get the actuator out? Thanks for any advice!
