What does your vag-com log look like? You may have the same issue, i.e. no start, however the cause and actions required to remedy might be quite different.

If you fix the relay by tapping on it you are really not fixing it because it will happen again at decreasing intervals until the relay burns out. To save yourself the hassle just get new relay that cost around $25.

Can anybody help with where to buy these, or even where are they located, and how to they look.
I googled to all my known sources, and these two items are literally showing up only on this forum.
I have weird starting issues, and have a feeling these might be exact culprit!
As I tried everything, and there is no codes.

I've have a 2005 A6 quattro 3.2 that turns over but won't start giving no codes no check engine lights on it's the strangest thing. Was running fine then out of nowhere I take it to work park it for my shift and it has not started since. I've changed the fuel filter, vacuum lines, fuel pump and checked all the fuses nothing has done the trick. Does anyone know where the relays are located for the fuel pump. I am very new to the Audi world so really know nothing about this car but I couldn't pass up the deal I got on it now I think I know why. Hahaha also I was reading up on a high pressure fuel pump in these cars where is this located if anybody knows. Any help would be fantastic cause I am at a loss as to what the hell is going on with this car. Thanks

The fuel pump fuse is on the passenger side of the car (right) and I'm pretty sure it is identified on the cover you remove to access the fuses.
