GTW w181 Park Assist unavailable
DI_w124 Cruise control disabled

Initially the EPAS error occurred a few times when it was intermittent but then it totally failed and no more errors.

Had mobile technician on-site and the grounding stud torqued off and was replaced.

Then the main wire harness on the passenger frunk crush pillar was observed to be frayed and chaffing. Conductors exposed.

On further examination there was also a fray marked area on the backside that was mounted against the frame pillar.

The wires that are damaged explain two of the errors when I did a wire trace according to the wire diagram and connector reference manual provided.

I will be attempting wire repair tomorrow.

I was told that the power steering motor bolts have been replaced. The NHSTA procedure mentions applying a wax sealant but I see no evidence of the sealant.
