My my name is Tony in Michigan. I am also new to the TDI world. I just purchased a 05 Passat TDI. Currently I working through some issues. It currently will not start. The motor turns over and comes close to starting but just wont. I changed the filter this morning but this made no difference. The car will start for a couple seconds with starting fluid. So it is defiantly is a fuel delivery issue. The lift pump does turn on but I have not pressure checked it yet.
