I have a 2009 early season Jetta TDI with slightly over 60000 miles. I had a HPFP failure shortly after 10000 miles and no problems since. I popped a CEL 12/2011 and took car into dealer (I live over 3 hours from the closest TDIclub recco shop). They replaced the EGR valve (for $400!) with the CEL coming back in less than 30 miles. They then replaced the DPF with the same result and then the catalytic converter (both under warrantry) again with the same result.
The dealer and techline were stumped and told me they would research further when the most experienced tech was back from cancer surgery . For the next month I a called back a couple of times and he was still sick. I suggested maybe a wiring harness problem but they wanted to wait for the tech to return. Then the left low beam headlight bulb went out. After replacing it, about 15 miles later the CEL was off and has remained off the last week. Thought it would be good info for the database. I did notice I am getting 2-3 mpg better with all the replacements.
