Check Engine Light

The light is reset with a smallish BMW or aftermarket device that can be purchased relatively inexpensively. On Ebay, for example. There's a port it plugs into under the hood, then follow the device's printed instructions, which is, push a button, basically. Very easy. Get on with your bad self in that Bimmer.

A clogged or defective fuel filter will very likely cause a check engine light. If it is suspected, it should be replaced.

no

Check engine light? Remove the battery ground terminal for a few seconds. If you still have the problem, the light will probably come back on. I have never had that light come on except on start up which is normal.

from what i gather from my book it to do with emission system i only know cause i been looking all over net as to why mine wont start and my check engine light is flashing not staying on

There could be many reasons why a security light is staying on. There may be an animal that is in front of the light moving all the time such as a cat or even raccoon. The light may also be defective.

The check engine light came on because the ECM (Engine Control Module) detected a problem. Until the problem is fixed the light will continue to illuminate. Just resetting the light will not fix the problem. Have your local auto parts store read the code(s) from the ECM. The code(s) will help determine what the next step should be. Your auto parts store will provide this service for free.

Can be many things. Have the ECU scanned.

Not really. This sounds like a bad ground on the battery or the regulator.

unhook battery for a few minutes that should do it otherwise have an auto prats store turn it off with a code reader or diagonstic tool

There are pages and pages and items that can cause a check engine light. You need to have it checked for codes with a scan tool. After repair light can be shut off with scan tool.

On our 2001 1.6 Vitar it was the EGR (exhaust gas recirculation) sensor that had failed. Cost £160 to replace. You can reset the light off for a time by disconnecting the battery for ~5 minutes

There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.

After repairing the cause of the code, you clear the code with a scan tool.

I clear the check engine light with a Scangauge II. But most ODB-II devices can read and clear the code.

As of yet, the time machine has not been created, however, HG Wells wrote a book about what it might be like to take one on a ride.

Go to your local Advanced Auto. or Pep boys or whatever auto parts store you have locally and ask them to check the light and they will hook it up to a little sensor, tell you why it's on and reset it so it turns off.

Check the gas sensor which may be located inside the gas tank on some models. The wire deteriorates that connects it to the gas pump.

O2 sensor circuit malfunction (sensor 1). I got this directly out of the Haynes Repair Manual, so I personally suggest you replace your Oxygen sensors.

Go to Auto Zone, they have a computer they can plug into the engine and it will tell you what is wrong, they will do it for free.

As specified prior go to Auto Zone store, they check it for free.

Take it to Auto Zone and they will read them free.

Just because it seems to be running fine does not mean there is no problem. It also has nothing to do with changing the oil. It is on because there is a problem with the emissions system. Have the computer scanned and have it fixed. Damage can occur to things like the catalytic converter if you continue to drive.

sounds like i would check spark plugs first but im no mechanic and spark plugs arent that pricey and can cause that type of problem. Check your computer fault codes, I would tend to suspect that your catalytic converter is clogged, creating excessive back-pressure.

I am not sure but I think you have to replace the oxygen sensor. Hope this help.

try a computer reading device that links with cars computer. they're not cheap you can rent them at most auto parts stores. not only can you turn off the light you can read whats the problem with the engine to cause the light to come on .

If you are having problems with starting your car, the car stoles on you as you drive or come to a stop sing, the serive engine lights are on, then you have a problem with 2 sensors. You need to replace them both. If you take to a mechaniv shop or dealeriship it will cost you between $300-$500.
