My mate's my2000 dse has the same problem. He had another turbo fitted, all associated hoses/intercooler removed and checked out. Map sensor and hose replaced. Egr blanked. Still the same. Scary to drive pulling out of junctions or entering roundabouts. So if you find cure please post on here.

Injection pump Quantity adjuster problem or faulty MAF sensor.
Earlier diesels(Without EGR and MAF) are much more reliable beasts.
