We had a 56 plate galaxy [2.0 tdci engine] in work recently, topped the tank up with £40 worth of bp ultimate unleaded then drove 90 miles with it running like a bag of shit drained it off and refilled with diesel and a new filter and it drove fine. That said theres a high chance it'll be needing a pump & injectors permaturely.

very expensive business thats for sure, about £1k for a pump on average, injectors about £250 each + fitting + programming & as said it may be tested and rejected by the warranty company so don't bank on "it's under manufacturers warranty, i don't care.."

On a side note those injectors [2.0 tdci] are on a europe wide backorder indefeinatly apparently and have been for about six weeks so far So don't bank on if it does go wrong i'll be back on the road next week cos theres a high chance you won't if you have a 2.0 tdci dw10!
