Just the same as any 642 engine, get it to full temperature and use a torque wrench set to 20Nm to undo, any more and they can snap off.
You need a long/deep socket.

No need to replace them all straight off http://www.mbclub.co.uk/forums/engine/120140-glowplugs-replace-all-replace-failed.html
With the search c=facility, it needs a little patience or search through Google for Mb Club posts.

thanks for that
I was wondering if there was a particularly difficult one to get to or more likely to snap

just did a scan to reveal 1-5-6 are the culprits
with three gone thought to do the set
