I've got a receipt in my service history for both the pumps being changed by a specialist, cost over £700 to supply and fit. Is it the lift pump in the tank or the main injection pump on the engine?
There's an article in PPC or one of the similar mags this month about the 325tds. It mentions in there about the pump problem - I'll wander over to the shelf and see if it mentions a cheap fix in the article - can't recall one though
