Did you look in the glovebox for the Warantee information? The law states that you must get a copy of the "federal emissions warranty" when you purchase the vehicle.
 
Did you try typing googling "federal emissions warranty"? I get 208,000 hits on that one. You should be able to get all the details you need.
 
DONT FORGET... Your "federal emissions warranty" may be different depending on the year of your vehicle. (3year/50Kmile, 8/80 , 10/100...etc)
 
I beleive your 2000 MY has the 10year/100,000 mile "federal emissions warranty"

The SEL employs the 2.0L Turbo, while the S and SE trims use the 2.5L (normally-aspirated) engine.

Ooops, you're right. Jetta SportWagen has a 2.0L Turbo (just confirmed that on the U.S. VW website) with 10.3:1 compression, but there's no turbo in the Sedan.

Fuel pump relay??? by chellevw

I have a 2003 Jetta, 2.0 ltr engine and last week it wouldn't start. This has never happened before. It was suggested to me that the fuel pump may have gone bad, so I bought a new one and it turns out that wasn't the problem. Now it's being suggested that it may be the fuel pump relay...it just won't start, it seem as if no fuel is getting to the engine and I have a half a tank of gas in there. Any suggestions? where is the fuel pump relay located???

You need to stop throwing parts at the car and back up, take a breath, and try some basic diagnostics or have someone do them for you.
 
One simple test might be to spray some starter fluid in the air intake. If the car roars to life for a few seconds, then yep you have a fuel problem. If it won't start even with starter fluid, you probably have an ignition issue, such as bad coil, etc.
 
If you'd rather take it to a shop, they can install a fuel pressure gauge on the fuel rail and test for fuel pressure, and can test the injectors for a pulse with a NOID light and make a simple test for spark.
 
Sudden fuel pump failures are rather rare actually. They usually wheeze themselves to death. You should be able to hear the FP relay click when you turn the key to ON.
 
Relay location on the thirteen position auxiliary relay panel, above relay panel:
1 - Auxiliary Emergency Flasher Relay (404)
2 - Relay for Motor Remote Unlock Rear Lid (79)
3 - Starting Interlock Relay (53) (185) (465)
4 - Fog Light Relay (53)
5 - Control Module for Multi-function Steering Wheel (450)
6 - Control Module for Multi-function Steering Wheel (450)
7 - Daytime Running Lights Change-over Relay (173), from April 1999
8 - Daytime Running Lights Change-over Relay (173), through March 1999
9 - Dual Horn Auxiliary Relay (53)
10 - Glow Plug Relay (180)
10 - Warning Lamp Auxiliary Relay (200)
11 - Park/Neutral Position (PNP) Relay (175)
12 - Power Supply (Terminal 30, B+) Relay (109)
 
Relay Panel:
1 - Dual Horn Relay (53)
2 - Load Reduction Relay (18) (100)
4 - Fuel Pump (FP) Relay (409)
V - Wiper/Washer Intermittent Relay (192) (377) (389)
VI - Wiper/Washer Intermittent Relay (192) (377) (389)
NOTE Number in parentheses ( ) indicates production control number stamped on relay housing.

2001 Jetta 1.8T ticking by swade1
Oct 16, 2008 (7:22 pm)

Check engine light started flashing, code stated cylinder 1 running too rich, replaced all 4 coils. Code went away, now enginge is ticking. Sounds like coming from the head but not sure. Any suggestions to what next?
 
Also, taken to mechanic and told 20W-50 synthetic should make ticking go away. After 4 days it is louder. It is in the freezing temps here. Should I really be running this weight on this engine?
