I tow a caravan with my T6, Kombi 2018, after opening the tailgate whilst still plugged in (which stops electric opening), the door now only rises to half height on opening with the door handle, I never use the key fob (never really needed to) as I just walk to the door and pull handle. reading various threads some talk about flashing lights etc has emerged, and I am not aware if a child lock is fitted to the rear door. No kids about. can this be sorted by adjustment somewhere or any useful info to sort this out please. Thanks Neil
