I had a similar problem on my laguna 1.9dci.

Took 4 goes at the garage (under parts warrenty, cost me 2 investigation and 4 hrs labour) and they eventually changed a "vacuum valve" they were no more specific than that and as they were not charging me due to the 3 other goes failing I left a happy man.

First try glowplug
second try glowplug heater wiring fault
third try glowplug heater controller

I tried to tell them it probably wasn't the plugs but they are the experts.

also the EGR was mentioned but the "vacuum valve " fixed it

All OK now 6 weeks on. Much nippier and better MPG.
Currently in nash's garage:
