Hi..

Hopefully i can help..

Normally you have to remove the intercooler that sits over the top of the engine to get good clear access to the plugs...all you need really is time/ long reach socket that fits the glowplugs long extention ratchet..wd-40 and lots of it..if you want to prevent them breaking in the cylinder head...they will or should be wired up via a small bolt on each of the 4 glowplugs some are just plug connectors to remove.....you need to remove those first making sure you don't loose the bolts as they are quite small and take prior note where each wire-ring connector went on each plug if required....Ideally you'll need to soak the treads between the glowplug and the cylinder head orifice with lots of wd-40 and leave it for a while to soak in, sometimes pre-heating the engine up can help greatly also if need be,i prob would advise that..as i do that myself all the time when doing glowplugs on any car/van....then with the correct sized long reach socket "test fit on your new ones" extention/ratchet then slowly but firmly undo anti-clockwise till they start to free off....if whilst removing they become or feel tight then turn them back in clockwise and re-soak the threads and then slowly back anti-clockwise again and keep doing that till they eventually come all the way out...Then refitting is basically reversal of removal maybe adding a little copper grease to the new plug threads and screw in each plug by hand first till they seat in the threads "properly" then tighten each plug with your socket/ratchet and torque to 25-30Nm or as tight as they where before but not too far as you could strip the threads..then attach the cable over the 4 glowplugs and then the small nuts last..and that should be that,refit everthing else that was removed to gain access - then test engine... so any diyer can do it provided thay have the tools to do so and have replaced them before..you just need to be extra carefull with them as they arent like sparkplugs.they can in some case snap..just take you time with it...but never stick to one quote from any garage phone around a few other good garages and see if anyone can do it a little cheaper..I do hope this helps
