I spent ages chasing round P0400 codes on my DTi, think I pretty much renewed all of the vacuum pipes and elbows (including the large one at the rear of the head connected to the vac pump), the EGR and swapped solenoids around. Just when I think I'd fixed it the problem the diesel pump died!

Check all vacs, clean egr, clean intake if possible, clean boost sensor.

cleaned everything & still had eml on. the vac pipes looked too short, making 90 degree bends not right. i went to a scrappy & took a few. so now they are sitting around the engine ok. I did find one that had a minute split at a joint, so replaced. also replaced egr valve with new. and pleased to declare no more eml light. :y :y
