Question about 2002 Volkswagen Jetta TDI
Whether hot or cold engne has low power on startup. Kicks in reliably at about 2300 RPM. 2002 Jetta TDI, 1.9 L. engine, auto trans. 95,000 mi.
I have the same year TDI. If I recall correctly, with this ALH diesel motors, they are the first VW TDI diesel to have some sort of electronic control with the fuel/throttle. Meaning, there is no line that goes from the gas pedal to the throttle.
I sincerely doubt it would have to do with the timing as that is a constant and not a variable. Lack of power from that wouldn't just be at start up.
I would look first at possible fuel delivery issues. If I come across anyone that may be able to give better advice, I will definitely pass it along.

There are a few things that you may check but i will not guarantee that they will work. check the throttle cable for any slack or wearing. also try to check the idler.
