I have a VW Jetta and the check engine light keeps coming on. How do I turn it off? Nothing wrong with car?

Answer 1

One problem that is happening on alot of cars these days in relation to the check engine light is that your gas cap may not be on as tight as it should be. This happened to me recently with my 99 Jetta Wolfsburg and I brought it the the garage, he put it on the scope and the reading was that vapors were escaping. The fuel cap wasen't tight. You have to make sure that when you put it back on that you make it 'click' a few times. Light went off--haven't had problem since.

Answer 2

Depending on the year, a place like auto zone can hook up their computer to your car and tell you why the light keeps coming on. If they can't do it then the dealer can. Auto Zone does it free. There is a reason that the check engine light is coming on, it doesn't just do it for fun. You can disconnect the battery cable for 1/2 hour or so to reset the computer and the light may or may not stay off. A lot of times when the check engine goes on sometimes and off other times it is an oxygen sensor going bad.

Answer 3

The only thing I can suggest is to either have a mechanic run a diagnostic on it, disconnect the battery to reset the computer, or ignore the light. I drove my son's Jetta from Oregon to Texas and the light came on in Flagstaff. I stopped in to a mech there and they said not to worry. I had oil, the temp was normal, there was nothing wrong with the car. So I drove the car the rest of the day, with the light on, next morning it was off and it has not come on since. Perhaps, it is the make, model, or who knows. I do know that my son has had more recalls on his car than "carter had little pills". Good Luck

Answer 4

I had the same problem with my 2000 Jetta, and there is also nothing wrong with my engine. I was told that the pressure in my gas tank was off. The mechanic took out the fuse to the check engine light and replaced it thinking that was it, but it wasn't. The pressure might be off because the gas cap is cracked, either way it needs to be checked out. That's what was wrong with mine. Good luck.

Answer 5

The bad news is you still have to take it to a mechanic. They have the ability to reset the system so the light doesn't come on. However, it is still possible that something may be wrong that you're not aware of. I suggest having the mechanic run a diagnostic to be sure.

Answer 6

The check-engine light comes on for a bajillion reasons. Youd have to take it to someone with a diagnostic tool(i.e dealer, mechanic,) to turn it off. Fortunately, the check-engine light usually doesnt indicate a major problem and sometimes can be driven indefinitely after it goes on(but for the sake of my conscience, please get it checked on lol).

If it starts to flash, time to worry.

Answer 7

there has to be something wrong with the car otherwise the light would not be on. take it to the dealer or a reputable shop and have the problem addressed. once the dealer or shop fixes what is wrong with the car they will reset the light for you.

Answer 8

Well, the light says otherwise. Perhaps fluid levels are low - coolant, oil, brakes//charging system??// It is complaining and you are not listening. See a dealer and let them go thru it if you do not want to(and no they won't just take out the bulb) It takes too much time to do that.

Answer 9

spark plugs are good for about 60K After that renew. Me I change them every year with new(or 12K) That is not saying they cannot "fail" at any time. Could also be carb adjustment or ignition timing is off or left rear tire is low on air.

Answer 10

How do you know nothing is wrong with the car?
If nothing is wrong, it shouldn't be on. It may be a bad sensor somewhere, but that is still something wrong.
