I have searched and read and searched and read more but here it goes. Ok VW people. Question. Bought a 06 TDI Jetta a couple of weeks ago. Occasionally it cuts out/studders around 3700 rpm under load. It idles oddly some and I can replicate a chug chug if I feather the throttle and let off. It has died a few times now and the last time it died and would not restart. Finally got it started and has ran since. No codes being shown from VCDS. I thought it was a in tank fuel pump. Replaced that Wednesday and no change at all. Tried a new mass airflow and no change. Fuel filter is new. Injector balance is within the +2/-2 range. Taking to a friends tonight to put on lift and check for boost leaks on turbo and intercooler. If I don't find anything I'm lost. Anyone have any ideas? I stopped my the Import Doktor in Louisville the other day and I have an appointment scheduled for Tuesday. The owner said to check for boost leaks and we tried the new maf in his parking lot.
