What is code P0676 WK CRD?

I think it has to do with glow plugs, but not sure which one.

correct that's #6
0675 = #5, etc

if you have that code DON'T WAIT to address it - I did, and that was a mistake on my part.....

Some have said this theory is not true and its just a coincidence if others fail in short order. IMO, it's best to do fix it ASAP not take a chance, and in fact do all 6 if you can afford it.

I believe it would have been a simple matter to replace the plug if I had jumped right on it instead of putting it off
