Glow plugs..

So I got the P0676 code (Cylinder 6 glow plugs circuit). I've already read on the repair procedure but do have a question. Should I replace all 6 plugs or just #6? Also should I replace the glow plug controller? Thanks guys.

If it were me, I would replace the glow plugs and controller, along with the intake manifold gaskets since it will need to be removed. That is what I did. If you go with FCP Euro, you will get a lifetime warranty on all of it.

So what I ended up doing was replaced all glow plugs purchased from rock Auto and also replace ALL intake gaskets. No more CEL after I cleared the code. Also did not replace control module. Job was actually pretty easy. Also cleaned my EGR as it was caked in carbon.
