BX TZD Troubles - Help!

Anybody a clue on what may be causing a starting problem on the wife's 156K mile TZD turbo BX?

It just had a new fuel filter & housing fitted after the old one started leaking air in. Since then it's been a bitch to start, even with a new set of glow-plugs fitted. Giving it about half throttle as it turns over seems to help, though even then it won't always catch. Once it does spin up, as long as you lower the revs gently initially to tickover, it runs fine and pulls like a train.

Haynes manual talks a bit vaguely of some models having a post-start glow-plug power-on period of 3 minutes, but as that manual covers C15 vans, diesels, turbo diesels, Bosch- and RotoDiesel- equipped models I can't make out if this is relevant (or indeed if it is a) fitted at all or b) anything to do with the problem) Could there be a problem with air still being in the system, and would that only affect starting? Could it be the thermostatic idle control?

I'm experimenting with it at the moment, and I did read that if you stop the engine by stalling it from idle instead of turning the ignition off, and the car starts OK subsequently (after cooling off) it may be a good diagnostic - but of what?

Anybody encountered this at all?

Thanks

Tony
