After another shop couldn't (or wouldn't) do so, Griffin promptly diagnosed that our TDI's aftermarket 'Contain Kit' (2Micron Filter)—designed to capture shrapnel from a failed TDI high pressure fuel pump—had functioned properly and saved the fuel rail and injectors. They procured the tool needed to replace the HPFP, as well as a replacement filter, thoroughly cleaned everything, and got us running again for just over half what the other shop had quoted. Kudos!
