Another one is diagnostics. I never used to charge for it if you had me do the work. But with the costs of the tools needed to diagnose things these days I had to start charging for that also.
I absolutely charge for diagnostics. A busted coolant hose is one thing, but if tools and SI come out there is going to be a charge unless I don't solve your problem. The main value you bring as a technician is the knowledge needed to fix a problem, not the ability to turn wrenches. Why would you give away your most valuable asset for free?
The idea of not charging for diagnostics is, in my experience, related to the bad reputation the car repair industry has for not fixing things right. Customer doesn't want to pay for diag, shop is no good at it, so the part that fixes it 70% of the time is thrown in and doesn't fix it. Guess what? Shop makes money installing the wrong part AND the right part next.
I think the car should be fixed right the first time, but doing so requires knowledge, tools, and information. None of those are free, and all of them have to be capitalized.
When you explain it properly (and politely) customers understand. The ones who don't are probably not the ones you want as customers.
It gets a lot more complicated after that.
