Hi everyone,
Like many I've had the glow plug error for #5 plug. I've read a lot of posts on this and decided to just replace the glow plug module and see if that worked (as it has for others). I found a video for replacing it without removing the inlet manifold and decided to give it a go. The guy in the video makes it look easy. It was a pain in the arse and took me a couple of hours. But, it worked and my fault code is gone. It's doable but patience is required
Here's the video I used.
