Well I tried to tackle the module removal last night, and was immediately halted by not being able to get the torx wrench (t20) to seat in the bolt head. Any ideas why?

Sometimes they are loaded with dirt/gunk try shooting some penetrating oil on it and get something small pick like to clean around it. Then if need be use a small hammer to tap into the bolt head.

Yeah I thought of that, used a push-pin and it did not feel like anything was in there. Then this morning someone said there might be a post in the center (security feature) so make sure my T20 torx has a hole in it, but I did not feel that either.

Hello Paul,

Try to clean out the bolt head using carb spray and a toothpick. Here is a guide and video on doing that job maybe this can help.
