Do we change glow plugs as part of a service/interval?

Chaps

When do we have to change the glow plugs?

Certain age or mileage or just when they need changing?

Cheers

TBH unless you notice cold starting issues/delays which may be other parts anyway, then I'd leave as is until an issue is present, although if cheap enough, then swap out as its not a hard job overall.
