Glow Plug Warning.

[oldjohnny]

Hi Folks.

I have an intermittent glow plug warning light for her indoors 2012 e class e220d. I will get it checked out first of course, but I see Febi X 4 advertised at the right money. Has anyone any experience of replacing these with non oem and is it best to replace all at the same time?

would rather go with NGK, Beru on plugs.
Yes replace all 4 at the same time, its like would you replace a single spark plug.....
