20 Most Recent 2002 Volkswagen Jetta TDI Questions & Answers

Try moving the fan blades by hand to see if the fan spins freely to see if the problem is frozen bearings in the fan motor. Replace the fan motor if it doesn't turn. If it spins freely disconnect the wires and hook the fan directly to the battery using a jumper. If it runs the problem is most likely the thermostatic switch. If it doesn't the fan motor is bad.

The glow plugs are plugged into the cylinders. They basically do the same that spark plugs do in gasoline/petrol fueled engines.

It is quite rare that glow plugs heater circuits go bad all at once. Test also the wiring harness.

Here a forum that can help you a lot. Picture below is from the tdiclub.com forum in this link:

Every bulb on the outside of your car has a safety function. This may seem obvious, but think about how often you see somebody driving around with a tail light out, or with only one brake light. The fact is these little bulbs are often neglected. Many people don't replace them until they get pulled over and have to try to avoid the fine. It only takes a second to inspect all of your bulbs .http://www.xcardiag.com/ Don't be a slacker. Take 5 minutes and do a walkaround. Even if you find a dead bulb, we can help you replace it in no time. The last thing you want is a ticket or an accident.

If this is a OBD2 scanner code you'll need to recheck it as it should be a letter and four numbers. Without the letter you can't translate where the fault is.

My personal suggestion would be to go for these repair catalogs. I know this website www.reliable-store.com that i used to get manuals from, and they have all models online. I also brought for my 1989 BMW, such old model, they had it and it was very good manual. Go ahead, I bet.

If the system is not working even when you press the buttons on the door, then the problem is not with the remote control. I would first check if all the fuses are ok, if they are, I would check the wiring on the door to make sure there are no wires broken of chaffed. Focus first on getting the system working with the door buttons and after that is ok, the move on to the keyless system in case it still does not work. Hope this helps.

Seems like a pin or clip has become loose or misaligned where the shifter meets the transmission. A simple answer, but you may have a simple problem.

Installing Note: Install a new pump-injector unit, also replace the corresponding adjustment bolt in rocker arm. For every procedure that requires adjustment of the pump-injector unit, the adjustment screw in the rocker lever and the ball pin of the pump-injector unit must be replaced. New Pump-Injector Units are shipped with O-rings and heat protection seal. Install the pump-injector unit again, replace the O-rings and the heat protection seal Pump Injector Unit O-Rings, Removing and Installing . Before installing Pump-Injector Unit, check that the three O-rings, heat protection seal and securing ring are seated properly. Note: O-rings must not be twisted on themselves. Oil O-rings and insert Pump-Injector Unit with great care into cylinder head seat. Using uniform pressure, push the pump-injector unit into the cylinder head seat onto the stop. Insert tension block into lateral slot of Pump-Injector Unit. Note: If Pump-Injector Unit does not stand at right angle to tension block, securing bolt can loosen and thereby cause damage to Pump-Injector Unit / cylinder head. Align Pump-Injector Unit as follows. Screw the new bolt into the tension block so far that the pump-injector unit can still be lightly turned. Now align Pump-Injector Unit at right angle to thrust bearing of camshaft. Using a caliper gauge (measuring range minimum 400 mm), check dimension "a" from the outer edge of the cylinder head to the round surface of the pump injector unit. Cylinder Dimension a 1 333.0 0.8 mm 2 245.0 0.8 mm 3 153.6 0.8 mm 4 65.6 0.8 mm Re-align Pump-Injector Unit if necessary and tighten securing bolt as follows: Tighten the securing bolts to 12 Nm and turn an additional 270 degree ( 3 / 4 rotation, additional rotation may occur in several stages). Install rocker arm axle and tighten new securing bolts as follows: First hand-tighten the inner bolts - 2 - , then the outer bolts - 1 - equally; then tighten in the same sequence to 20 Nm and 90 degree ( 1 / 4 turn). Place a dial gauge as shown onto the adjustment screw of the pump-injector unit. Rotate crankshaft in direction of engine rotation until rocker arm roller stands at camshaft point. Roller side - arrow A - is positioned at the highest point, dial gauge - arrow B - is positioned at the lowest point Remove the dial gauge. Now turn adjustment bolt into rocker arm until significant resistance is noticeable (Pump-Injector element stands at stop). Turn back adjustment bolt from stop approximately 180 degree Hold adjustment bolt in this position and tighten lock nut to 30 Nm.
