hi mate :)
if you could title future threads as i have done this one it would be most helpful ;)

now...i'm no derv expert...but i believe if you can remove spark plugs then you can remove glow plugs...i'm sure one of our diesel owning enthusiasts will be along shortly with the full ins and outs ;)


edit...beaten to the 1st post lol

IMO you need to get any error codes read, the glow plugs may be ok?

If you do need to change them get a hold of some PlusGas penetrating oil, reputably the best there is, ditto what dailydoggy says & as Deano says the inlet manifold will have to be removed.
Using a Torque wrench, set just below the breaking torque for the plug, try and undo them. If they don't move apply some more penetrating oil & leave for 5 mins then try again!
Hopefully they'll come out OK :thumbsup

As suggested, firstly satisfy yourself that the battery is 100% sound and then have a diagnostic scan done:cool

When removing the glow plugs I recommend removing the inlet manifold even if you believe to replace them without doing so. It will make things far easier and will prevent you putting the replacements in on an angle and cross threading them:thumbsup
