No problems starting V70 in winter/summer. Simon's video says the resistance should be 1 ohm or less. Soooo - should I change them?

no they will be ok , you get a specific fault code if they are faulty it tells you which one .
Be very wary testing glow plugs on 12 volts the newer ones are 7v and you can easily blow them!
