Glow Plugs - Mercedes Benz

[junglie]

Morning all,

I have just had the glow plug light remain on after starting the car (C320 CDI with 68k / FMBSH) which suggests one or more of the plugs are on their way out.

Rather than do one, then another in a month and so on, I am planning on changing them all in one go. Actually, the garage will be doing it as i know there has been issues of home mechanics snapping them off in the head.

Are there any particular makes that are preferable?

Bosch or Beru.

Bosch or NGK. Owt else is false economy.

Thanks - search eBay for a set or is there a suitable other method?
