my vehicle threw CEL P0676: Cylinder 6 glow plug circuit/open few weeks back. i used it daily till now and had the time to go in and replace the plug as well as clean up the intake system carbon build up. i figured i'd do all 6 plugs & replace the gaskets as a preventative maintenance.

so last night i started at cylinder 1 and found that the tip of the glow plug electrode, below the collar, sheared off when i broke the plug loose.

i am looking at options and would really appreciate any direction. i was about to order a glow plug removal kit but decided to consult the forum first as the tips of the plugs are ceramic i am not certain extraction by tapping and pulling is possible. also the directions i have found for this process generally show much more of the plug body &/or electrode remaining in the GP hole.

thanks
(i posted this same question in bimmerfest as well)
