Summary
Complaint • Fuel filler flap protrudes from side wall • Fuel filler flap not opening Cause Under analysis Remedy Create TIPS case with the below information and send to the Body/Chassis/Entertainment Inbox: Open the flap and take a detailed photo of the fuel tank strap attached at the hinge arm. Is the attachment bent or kinked? Are there pressure marks in the recess where the retaining strap is located when closed?
