Re: Anyone remember Haynes Manuals?
With everything computerized, and undocumented by the manufacturer, "not a DIY job" is often the sad truth with more-recent models.
My 2015 Volvo XC70 was recalled once for a firmware update for the differentials. I'd be leery of trying to service a computerized differential without comprehensive documentation. What sensors is it using? Do they need to be recalibrated afterward?
And that car isn't nearly as bad as current Volvos, with their accursed touchscreens and spyware – which are now par for the course.
It's a pity, because DIY auto repair used to be a good way to learn plenty of useful skills, like problem diagnosis and tool use. Oh, well. At least I can still work on my 1991 Toyota Truck, and try to interest the grandkids in it when they get old enough.
