Haven't you found a friendly independant to work for you? Am dead lucky with my LR, one of the Technicians from the main dealers does mine after hours, he's a bit of a TD5 loon and doesn't charge the earth, even keeps his LR overalls to do the work!
Your right Aaron, my mate had a look but wasn't sure if it was the fuel pump, but I didn't want to spend a grand and find that wasn't the problem, fingers crossed.........
