Question about 2003 Volkswagen Jetta TDI
I have a Chiltons manual and it says to disconnect the engine coolant temperature sensor, but I can't find it with the picture they provide.
I'm not sure about a 2002, but I have a 2003 and we didn't have to take off the engin coolant temp. sensor. We needed the #4 glow plug replaced and this is how we did it. We took off the motor cover by undoing the threee bolts, then there is a rubber "bar" across in front of the injectors.. pull these up one by one by holding onto the ends and there you will find the glow plugs. You will need a 10mm deep socket to undo these. We replaced the last one on the right ( thinking that it would be the #4) wrong... the firing order is 1342 but the last one one the right is not #4, so to make sure that they wore evenly we replaced all four of them. When you have tightened in the glow plug(s) make sure you put the rubber plug end on with a "snap". Replace everything that you took off and put the motor cover back on. This worked for us hopefully for you, too.
