Text of the manufacturer communication
This Technical Service Bulletin describes the verification and resolution steps for the nut holding down the ignition coil grounding wire on certain B6.7O engines which may cause the studded capscrew underneath it to rotate when trying to remove the nut during a service event, resulting in the ring terminal on the grounding wire connector rotating against the side of the ignition coil and breaking off from the grounding wire.
