just incase anybody has a problem with their rear passenger door not opening on their doblo just ask me ,bloody 3 hours sorting out my door which wouldnt open yesterday,my 54 plate doblo taxi sliding door wouldnt open,couldnt see anything and decided 2 have a read of the owners manual and then discovered that when the fuel cap is opened the rear door wont open as a pin worked through the cap stops the door from moving back.took it all 2 bits and discovered the bloody mechanism is broken,removed the cable from it and put it all back together and hey presto the door is working now ,every day is a school day !
