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?

I have a 2000 jetta TDI 1.9L. The glow plug light is flashing off and on and the car is running terribly. Code is reading P0380/glow plug monitor circuit. what do I need to do to fix the problem?


the code is for the Glo-plugs circuit A --malfunction=== causes wiring--glow plug relay--fuse-- glow plugs---ECM. Check the relay and the fuse

The diagram in my haynes manual does not show some parts that are in my 2001 jetta tdi 1.9 turbo. i ran a diognostic and it says glow plug curcuit a malfunction, i changed the plugs and tested the coolant...


In addition to the 4 primary glow plugs, the cooling system also has 3 Coolant Glow Plugs to help provide extra heat to the cooling system in order to warm-up the vehicle's interior more quickly, and enhance overall engine warm-up time. (Example - Some Mercedes diesel engines use electrical heaters in the cabin because their engine is so thermally efficient.)
Likewise, this auxiliary source of heat from the 3 Coolant Glow Plugs is necessary because of the VW 1.9 TDI engines outstanding efficiency, which wastes very little heat.


The 3 Auxiliary Coolant Glow Plugs are located at the end of the aluminum cylinder head (in a protruding flange) directly below the vacuum (brake booster) pump, which also connects to a coolant hose.

tdisline_301.jpg
The 3 Auxiliary Coolant Glow Plugs use two (underhood) relays which are monitored and controlled by the ECU. During a cold start, the vehicle's interior temperature selector switch helps the ECU choose one of three modes depending on the amount of heat required to warm-up the coolant.

For example, Coolant Glow Plug #1 can be selected to operate all by itself, or #2 and #3 can operate together as a two-some, or lastly, all three glow plugs can form a triple source of heat for maximum enhancement of engine warm-up time.

After the engine is completely warmed up and the thermostat is open, the Coolant Glow Plugs normally shut-off and remain off unless the (thermally efficent) engine cools down sufficiently to have the computer signal them to come back on to keep the engine and cabin air warm. Extensive idling times at stop lights or in the driveway are scenarios where these glow plugs are most likely to recycle on and off.

In conclusion, the period of Preglow and Afterglow is determined by the engine's coolant temperature (during a cold or hot start), which helps the ECU select a predetermined time-cycle for the combustion chamber and / or Auxiliary Coolant Glow Plugs to follow.

Finally, one myth that needs to be immediately debunked, is the belief that the TDI's advanced Glow Plug System is linked to the opening of the driver's side door, which is false! It is also noteworthy to mention that some earlier VW diesel glow plug systems were operated in this manner, but not so with the advanced VW Jetta 1.9 TDI engine.

2002 VW Golf TDI - Live in northern ontario - -20's with wind chill. When I first drove the car this morning - error code (looks like a clock) on upper right portion of speedometer gauge. Just flashes on ...


Classic 109 relay failure.

Relay is for the Glow Plug system.

This relay provides the power to all of a TDI's engine-based electronics.

If the glow plug light comes on intermittently by itself, check your brake lights too.

A burned-out bulb will cause the glow plug indicator light to come on. Sometimes flashing is caused by a bad Brake Lamp Switch on the Brake Pedal. It was updated for free by VW .

If you can see it under the knee panel, the Brake Lamp Switch body should be Metallic Green....if it is Purple or Black it need updated.

2001 VW Jetta GL TDI will not start. I checked the battery, and it is fine. Engine turns over when I turn the key, but it seems like no fuel is getting to the engine.


If you have blue/grey smoke coming out of the tailpipe, you are getting fuel, you can also check to see fuel if you pull back the braided cover on the fuel line (left front side of engine compartment). If you see smoke, check the glow plug relay (180) under the dash.

I have a vw bora 1.9 tdi and the heater plug light has started flashing and the car says engine workshop


There are a number of different causes of this problem. Check all glow plugs. Check glow plug relay. If both are ok....This may seem unusual...Check the brake light switch situated at brake pedal. A faulty brake light switch will cause the glow plug light to flash
Good luck with it
