While I was in the showroom ordering my car, I asked my dealer rep at Pentagon about the HPFP issue, and he cringed, lol. He also said that the problem was solved with the N55 engine.

So, assuming that the N55 engine has solved the issue, start comparing the two engines. What is different in the N55 that doesn't cause the HPFP to fail like they do in the N54? Maybe then we can single out the problem.

I know we can't take their word that the problem has been solved because its too early to tell with the new N55's. But still, might be someplace to start.
