Well my wife's nearly 2 years of issue free driving on the ML has hit a snag. Got the lingering glow light, CEL, and P0675 (#5 glow plug failure).

The timing is pretty good, we've hit "almost summer" here in Columbia and so it is still starting ok.

However when I went to search for how to go about replacing the glow plug it appears that the chances of it breaking off in the head are very high based on how many sets of tools are out there for extracting the broken GP.

So how many of you have had experience with changing one of these out?

I contacted our local dealer yesterday and they said, we'll have to get back to you and I'm still waiting for a call back.

Anyone?
