Hey guys, I just joined this forum. I have a 2009 audi A5 3.2l S-line. I was driving the other day and my car stalled out and would not turn on. The check engine light came on after I was able to turn it on after about 20 minutes of trying. It stayed on so I drove home and scanned the code. The code was for the fuel pressure regulator 1. I wanted to order the part online to replace the faulty fuel pressure regulator but I wasn't able to find the part. I called a shop near me and they told me that there is no fuel pressure regulator but just another high pressure fuel pump underneath the intake manifold. So, if anyone could possibly give me a part number to the correct part that would be greatly appreciated!! Thanks
