hello AZ, I have a 2011 S4 with a no start problem and I'd love some help narrowing it down.
Its fuel related, it throws these two codes.
P0087 and P3045
From a bit of searching I seem to have narrowed it down to either HPFP (wtf happened to the price of these btw) or Fuel Control Module as the more likely candidates, or LPFP and Fuel pressure sensors as the less likely. I was wondering if it was possible to narrow this down. I do have vag com, but I'm not sure how much data I can get since the car wont start. I ran two output tests (fuel pump electronics and pressure reduction in rail). But I couldn't find anything else relevant. Ill post some pics (sorry they are cell phone pics of a laptop screen) As well as the bottom of the actual CELs since they seem to have information as well.
