glow plug fault/extraction problems

I have just had my 93k mile C220 2002 C class B service carried out and the number 2 and 3 glow plugs are seized in. (I believe the garage may have snapped them whilst trying to replace because they said the bottom part is jammed in carbon) The car has always started no problem, runs like a dream and the only fault is the glow light comes back on after start for 15 seconds as it has done for the last 15000 miles. I have been told mercedes have a specialist tool to extract this bottom portion? is this true or does the head have to come off for drilling out? Any Help would be great.

Also check the O2 sensor reactions... make sure they all work.

There should be tools to extract it... without taking the head off... depending on how deep it is in...If you are saying they got the threaded part out but not the rest... well... probably have to take head off...
