So...
2014 Audi S4, 40K miles.
Mods: 034 Motorsports ECU Tune, E40 Tune, Dual Pulley (186/57.5) running E42; hx, brand new OEM HPFP with Autotech; Brand new Flex Fuel LPFP. Blah.
-Before replacing both pumps with new ones (I had original OEM LPFP, and Original HPFP with autotech piston installed).
-Car then started stalling, and sometimes wouldn't start. Ran VCDS, first a low pressure side fault showed up so I replaced my original LPFP with the upgrade Flex LPFP.
-Car was fine until a week later when I threw a Rail Pressure fault, so then I replaced my original HPFP with a new Audi one, and reinstalled the autotech piston.
-Car was fine for a few weeks and then I started having start issues, and then eventually (today) it died on the freeway. Fun stuff. Used VCDS again, and now the same low pressure fuel side code, same I had a few weeks ago, came again:

I was able to start the car this morning after many attempts and did a WOT run on the freeway and all the fuel factors looked fine.
