ML320. Today we had the experience of the fuel door failing to unlock at the gas station. The owners manual came in handy and access to the actuator was fairly easy through the driver side first aid kit door. I lifted the lock lever up and ended up with the acutuator in my hand. There appears to be a couple of bolts that hold the actuator in place but they were missing and not to be found. My questions are: Is this a problem others have experience? How do you reinstall the actuator mounting bolts in this very limited space?
