I had long cold starts too no codes or anything, so i changed all 6 glow plugs and the module at the same time and now i have to issues at all , starts heaps quick.
I brought my glow plugs from ebay Bosch Duratherm and the module make was Beru.
Unless you have just done it I suggest fitting a new fuel filter.

Hoping to fit a new fuel filter this weekend. The two small hoses on top look like they might also need replacing soon. Where would be the best place to get them? Couldn't find them on rockauto.
I would just use fuel line from your local parts store but if you want the factory part I would try a Mercedes dealer.

One more question. I bought Bosch glow plugs. Has anyone had experience with NGK and Bosch? Is either significantly better than the other? If NGK are dramatically better I'll head down to Super Cheap and grab a set and keep the Bosch set as spares.
