2001 vw jetta 1.9 tdi timing jumped is there any marks to line the help put it back in time

SOURCE: how to replace a coolant temp sensor on a 2001 vw jetta 2.0

Yes it is that easy. It should be a 4 pin connector located on the transmission side of the engine head in a plastic flange. Best is to wait for the engine to be cold. Unscew the radiator cap to relieve pressure but screw it right back on. On the 2.0L engines when you unclip the coolant sensor little or not coolant loss will happen if you do this. Just unplug it, pull out the clip, pull out the sensor, and the seal which sometimes stays stuck. Install the new sensor with a new seal lubricated with some coolant, make sure it's well seated and reinstall the clip. The sensor is well seated if the clip fits right over the top, just make sure both sides clipped into position. Replug it fill the coolant with VW original coolant mixed 50-50 with water if needed and done. If you have a fault you might need a scanner to erase the check engine or fault in the cluster.

What's the reason for changing it? Eratic temperature readings?

Hi There,

Here's a step-by-step from some great guys over at TDIClub.com
for an AAZ (which I'm assuming you have)

It's pretty involved, and some special tools are needed. I've seen kits for sale

SOURCE: VW Jetta ESP issue

unless there is a ESP button (some cars have this feature, yours does not) no u can't turn it off. Have the system scanned by the dealer for trouble codes to help isolate the problem

SOURCE: 2006 vw jetta tdi service engine light reset

With the key in the ignition (but not turned), press and hold the Odometer Reset Button on the right hand side of the panel. While still holding that button, turn the key (although not far enough to start the engine) and then press and hold the Minute button on the left side of the instrument pane(if pressing doesnt work try turning the knob clockwise until service light has gone off and skip the pressing)l. Release both buttons at the same time.
