Random smells can trigger headaches for me too. When I was little it was Fanta or Crush, something about the orange. Now I found the Trader Joe’s blood orange tea has the same scent and immediately triggers something.

Diesel exhaust is another one, but that’s not just a scent.

Surprisingly anything else motor related is fine. I’ve been soaked in brake cleaner and race fuel and it hasn’t been a problem.
