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.
