A few years ago I had some body work done. When I picked it up there was a module that was dead. I can’t remember what it was but it wasn’t cheap. At the time I found out that it was caused by the buffer they used and they paid for the replacement. I’m thinking it was electric and there was a grounding issue.

Anyway. I am about to have some extensive detailing done and don’t won’t this to happen again. Any advice on avoiding this issue?

I really do not understand this thread.

What “module” was blown?

Why does the removal of headlights clear the problem of blowing the “module”?

Why not just disconnect the battery?

I did some digging and found a little more info. Unfortunately since the body shop paid for the repair they got the invoice. I thought I had a copy but don’t. I do have the one for the diagnostic. The code was P0660. One of the causes I found for that is a bad DME Control Module.
I’m pretty sure that was the one that was replaced.
According to the shop owner it is a known problem that buffing over the area can kill that module. I also seem to remember that its an improperly grounded electric buffer that does it. Also could be static build up I suppose.
I know that is all kinda vague but the owner retired and closed the shop so I can’t go ask him.
I was hoping someone here might have heard of this sort of thing and have some idea how to prevent it.
I know thousands of 911’s get detailed all the time so may not even be an issue.

This is a known issue on 997's. Static during polishing/buffing around the headlights, and even the headlights can cause the Front Control module to fail. Pull the headlights out if polishing them to avoid this issue.
