Take off the battery cables. Touch the positive and negative together for 10 seconds. Reattach the positive first and then the negative. Your computer will be reset to factory settings. Idle will be better, cruise will work and air will be fine at the idle position.

You can disconnect the battery connection and connect them again. If it has a check engine light, it will pop up again untill the problem is fixed. If you are trying to get an inspection, there is way around it but to fix it.

The front seat buckles have a micro switch in them, you may have to split the plastic off to get t it and then check the wires are not broken and if ok then use electronic contact cleaner and hope it works for you if not the dealer would be glad to sell you the whole assembly

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.

SOURCE: Key fob needs reset 2006 VW jetta TDI

I hope this might help. -- I had the same problem yesterday and fix the problem today. The steps on the manual (page 32) was too simple and wrong for my case. Read carefully the followint steps and thank me if these steps work. -- JB (owner of Jetta 2.5, 2006 model)

* The most important thing is to make sure that the LED in the driver side window frame stays blinking. The blinking means that the receiver has entered a programming mode and is waiting for the signal from the key. Good luck!

1. Insert the key with a faulty remote into the driver door lock and turn the key to the UNLOCK position 3 times in succession for at least 0.5 seconds each time, and within a total duration of 5 seconds.
: The system should now enter so called a "programming mode" and the window frame LED should blinking once every 1~2 seconds for the next 15 seconds. The faulty remote must be programmed during this period.

2. Aim the key to the (infrared) window frame LED which can be considered as a key signal receiver and press the lock button of the key fob and keep it pressed. While the button is pressed, press the unlock button three times in succession for at least 0.5 seconds each time.
3. Release both buttons.

* After all the efforts described above, the system should now acknowledge a successful programming by flashing the LED once every 1~2 seconds for more than 10 seconds. (Someone said that the small LED on the key fob should also blink a few times; although it didn't in my case.)

Jetta window will not go up or down had motor replace

No, the computer does not have to be reset. I would vheck the wiring in the door hinge area to see if they are broken. If so you will have to replace the harness.

Engine light came on and i cant get to go off.prior to that my jetta wanted to stall

probably a faulty O2 sensor. can be a DIY project, be sure to get the right one. Bosch makes it for all Jetta models - be careful in removing the wire. there is a reset button somewhere under the hood to reset the computer, telling it you have replaced the O2 sensor and validate the engine operation.

You need an OBII scanner. Any good parts store can reset it for you but have them read the codes and if it comes back on you have an issue that's triggering it.

How do you reset a low tire pressure warning on a 2008 Jetta?

#1 Make sure the tires are at the proper press and drive it for approx 10 - 15 minutes or disconnect the
battery for about 30 minutes (just don't do that if you have to get the emissions done soon, within 2 weeks or so you will not have enough memory to pass).
