Speaking with experience of the same engine in a Zafira A, you might start by taking a close look at the many vacuum hoses and their rubber connectors. A vacuum leak can cause the symptoms mentioned.

I had a saab 93 diesel which I think has the same engine.
I had the same problem which turned out to be the maf sensor which had an intermittent fault relating to temperature. Fault was more frequent when cold.
New maf fitted in minutes , problem disappeared .
Sorry, can't remember fault code tho

Have you checked the hoses and connections to/from the turbocharger and intercooler?
