Glow Plugs - Changing TDDi / TDCi

ok tips for removal. soak around them with wd40 and then drive the car so it warms up. note only do them with a warm car! when your done soak them again for about 10 minutes this will give you time to get the wire off etc. firstly you need to use a 1.4" drive with a long reach socket. do not use any bigger drive. crack them loose first shouldnt take much effort really, next undo them slowly but soon as you feel the tension getting tighter then turn them to tighten back up but only go about half a turn. then you turn back to losten them only go into the tension a little bit then repeat the process over and over. be patient and dont think you can go into the tension more because i guarantee they will end up snapping. light movements on the ratchet and hold the ratchet closest to where the socket fits on when your undoing not the furthest end of the bar. if you are patient they will all come out without any problems.
