I do apologise for creating another thread when it is closely linked to my previous one but I think it's only right since it's more than just a quick fillup with the petrol can. I remember watching Top Gear and Jeremy Clarkson driving an A6 (?) 3.0 V6 TDI (i believe) from London to Glasgow and back on 1 full tank. ** correct me if i'm wrong on the above info. ** Anyway, on his trip back he stated how with a Diesel, you can't simple top it backup once it's gone completely empty. You have to blead the system in order to get it backup and running... Now anyone have any idea what he meant & how you actually do it? What happens if it really does happen, who do you call & what do you do?
