Hi everyone, I'm after some help about glow plugs, I believe the car takes 4 of the expensive sensor ones, but I keep seeing conflicting info online. Can anyone help me confirm this, and help with relevant part numbers etc.

Its my partners old car she is giving to me as a project for me to tinker with, its a 2012 astra 1.6 ecoflex diesel.

Thank you
