W203 c220 glow plug stuck failure rates

[stewie]

Glowplug... "another plug " needs replacing, just how common are these engines to be doomed with snapped plugs? is it always a " head off " repair job?

snapped plugs are quite common. head removal? depends on who you trust to remove it for you. i posted on this earlier (yesterday, now!)
