Your OM617, OM616 as well as a multitude of other Mercedes diesels, and honestly diesels in general need a little extra heat to get going in the wintertime.
On these, the glow plug system is responsible for that, and non-functional glow plugs, or weak glow plugs can cause your cold starts to be troublesome, shaky, smoky or potentially no start at all.
When changing the glow plugs, it is wise to ream the holes, which is done by hand, very gently with a 7mm drill bit or reamer that has had the tip coated with grease to catch carbon.
The carbon buildup acts as a thermal conductor that transfers the heat from the glow plug into the cylinder head rather than into the prechamber where the heat is needed.
