My car is a BMW E46 320d that`s turbo diesel 2002 model facelift. I did already change the glow plugs, but that did not fix the cold start diesel issue. Found out that is was the glow plugs relay module. it`s often the module is you get fault code on every glow plug. this also apples to the M57 straight six Diesel engines and maybe other engines also with this DIY. ! have a nice day.
