Help with Broken Glow Plugs

[FiestaLee]

Hi everyone, I am new to this group and I'm looking for some advice/help. My son in laws Fiesta acquired a fault code ( P0380-60 ) which pointed to the glow plug area. So I changed the relay with no success, I then bought some new glow plugs and decided to change them, even though I have no experience lol. I was told that these plugs are not situated very well as they were at the back of the engine on the 1.4 tdci. Sure enough, I found them very tricky, so much that 2 snapped while removing them. I removed the glow plugs leaving the snapped bits still in the head ( about an inch of the tip on both). I've seen some extractor kits but I know I wouldn't be able to get the tools to the plug site. I'm assuming I would have to strip everything down to get to the head.?

Any help would be much appreciated

Cheers
Lee
