The problem is not the fuel exactly, he has told me the area where the box is, its a good 60 miles each way, over an hour probably, so 120 miles+ round trip. If there are issues at his place then I would need to bring it home, test the box to see if it's that and then return. So total of 240 miles and 4+ hours on the road, let alone time spent at his place and to be honest after reading leaves me 2 things, if I drive over and can't sort it there, is he going to let me bring the box back, if not its a waste of time, secondly after reading the threads, no matter what I say the issue is he won't believe me/listen.
I did offer for him to post me the box, i would then sort out at mine and then get the box back to him for a nominal cost £25, which would cover the cost of getting it back to him and a beer, if I can't sort the box out because it's faulty or whatever then he just pays the cost for me to return it. He said, that's a lot of money and refused.
He's getting TV for next to nothing and now thinks he should get his box sorted for nothing as well. I don't mind helping people out and don't always ask for a beer as long as costs are covered but he has had so much free advice on here and I am sure via pm's and still not getting anywhere.
