I helped a friend work for two hours trying to get his Audi started after a meeting. Turns out one of the fuses wasn't making the right contact. We changed batteries, tried to jump it, etc. Until I noticed the fuse in the engine compartment that wasn't turned like the others, we were going crazy tring to figure what was wrong and what to try next.
He sold it not too long after that and got a better car.
