Might be a long shot but it sounds like the EGR valve could be sticking. It happened on a Peugeot 307 I had (same 1.6 HDI engine) and could only be 'fixed' by revving the tits off of it. When it started happening on my current C4 I just unplugged the power lead to the valve and haven't had any problems since (apart from the engine management light on the instrument cluster, but that doesn't bother me).

Mind, it could be something completely different, but it's worth checking just to rule it out.
