Take to a major chain auto parts store and see if they will perform a diagnostic trouble code (DTC) check. Many will do this for free.

They can tell you the definition of the code, what the most likely cause is, and suggest a part to fix the issue.

The only way to "get rid of" the check engine light is to fix what is wrong.

The check engine light also known as a malfuction indicator light ( MIL ) will illuminate when a code is set in the ECU ( electronic control unit ).Ther are hundreds of codes relating to many functions of the Audi. The only way to find out what the code is, repair the problem and clear the code is with a scan tool or code reader. The dealer and many repair shops have them in various degrees of sophistication and expense but for the home mechanic a simple inexpensive unit can be had from a tool supply source. I have a nice Black and Decker unit that gives me the code and enables me to clear it. It also has a booklet listing all the codes. I also purchased an A4 shop manual to help me. The scan tool plugs into a port under the driver side of the dash. Hope this helps.

Need to have it scanned and checked for codes. Usually your local auto parts house will scan it for you.. If you're lucky they might clear the codes for you as well.

Write down the codes for future reference.

Sometimes disconnecting the battery for half an hour will clear them.

How to get rid of a check light with out scan tool


Check light is a warning sign of something faulty, like sensors,relays,solenoids, and even a short. So to get rid of the check engine you must run codes with scanner and fix it. No other turn around possible. If you tamper with the function of the instrumental panel it will cost you more. Plus is unlawful mostly in the 51 States to modify such thing to pass emissions. Good luck

Engine management light on car runs fine


Service engine soon or check engine light? Engine light needs scanned for codes. Service engine soon is for oil changes and such. To get rid of service lights, turn the key on, press the gas pedal three times within five seconds. The light will flash. turn the key off. it's reset. At least check or change the oil and filter though.

My 2006 sebring cuts out at 3500rpm, has engine light on, have replaced fuel pump and cam shaft sensor


Most auto stores (Autozone) will use a scantool to tell you what the problem is & clear off the check engine light. It is a free service, but I'd suggest bringing a pen/paper to write down the error code & Google it afterwards. It's definitely handy for getting rid of the check engine light.

Have you checked your gas cap? What was the reason for the check engine light coming on? If just a cap issue the light should reset on it own. If you want to get rid of it just disconnect your negative battery terminal for a minute then reconnect. You will have reprogram your radio stations.

How to get rid off check engine light in 04 Suzuki Forenza


A check engine light means there is a mechanical failure with the vehicle, and should not be ignored. Most part stores will read check engine light codes for you for free, and tell you what they mean. The only way to turn this code off is with a diagnostic tool they use. If you have already fixed the problem find a local parts store in your area that offers free check engine light diagnostics and ask them to read the does and turn the light off for you.

The check engine light indicates a need for a scanning with a engine scan tool (OBD-II perhaps).

An oil change will not get rid of this light.
