I have read that replacing the glow plug harness on the 02 cars fixes the trouble light issues. I have a 2004 PD Jetta with intermittent glow plug trouble codes. After testing and tightening all the usual suspects the engine still takes about 1.5 seconds to start (turning over after glow plug light is out) instead of the normal instant start. Should I replace the harness.
Where does the harness terminate on the PD cars. The 4 prong plug is not in the square harness holder behind the air box like the 02 cars.
