Thanks MikkiJayne.
That is the pump that I have in my cart on the FCPEuro website. VDO. Cheapest that I could find it listed for is USD $145.49, and I have bought from them before.
Good chance to buy a couple of oil fiters, air filters and perhaps the rubber seal for the fuel pump VAG-1J0919133A . <-- Is that worth getting? I already have a fuel filter kicking around I think. Bought a spare for my C4 A6 but I think it might fit the S8. Have to check the part number. Bosch iirc.
If I push the car, am I right in thinking that I won't be able to steer it very well and that the brakes won't work? It is a slight downward journey to the driveway then a sharp right and then a bit of an uphill push to the carport. How many 'friends' do you reckon it will take?
Thanks for the suggestion by the way.
