Rear passenger door jammed

[Barn.555]

07 D3 rear right-hand door is locked shut. I have removed the door trim and operated the cable, but its still locked tight. To confirm I was doing the right thing I removed door trim from other side and pulling on the cable unlocked that door. Talked to the dealer mechanic and he was stumped. He said had heard of older models requiring door skin cut (a bit extreme). Has anybody had this before or know of remedy?

I guess that by the amount of views but lack of replies that many of you have not had this problem occur. Well here is the update.
Today just randomly decided to try and open the door as normal, lo and behold it opened as casually as before it decided to lock itself up - however now it will not open from the inside. The only thing i have done to the car in between is raise it to offroad height to fit GOE transmission plate.
At least now it will be easier to replace the entire mechanism to stop future shut downs.
