You would need to list all the codes you received so we could help you isolate the problem. You may have a more major issue that needs to be diagnosed. I recommend having a mechanic come and diagnose the Check Engine Light for you if you cannot find the problems. You should not drive the vehicle until the problems are diagnosed or you could more damage to the systems involved.

Other mainly common reasons for a Check Engine Light are dirty mass airflow sensor, faulty head gasket, a malfunction with the fuel injection system, faulty emissions control part, damaged oxygen sensor, or defective spark plugs to name a few.
A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it`s in good condition. If you have a tank of bad gas in the car, your check engine light may come on.
This indicator is part of the onboard diagnostics (OBD-II) system. A Check Engine indicator will stay solid or blink. Blinking Check Engine Lights mean the situation is serious and you should slow down, find a safe place to stop, and contact a Volkswagen Service Center.
Just be sure to have your car inspected as soon as possible after the light turns on. Don`t neglect needed engine repair! If nothing seems out of the ordinary, you can continue driving the car. The cause could be anything from a faulty oxygen sensor to a bad MAF sensor.
Will your check engine light turn off by itself? In most cases, successfully repairing the issue that caused your light to come on will cause the check engine light to turn off automatically—but only after 10 to 20 “cycles”.
You can judge how serious an issue is by looking at the warning light. The check engine light can show up in two ways: Solid yellow/amber light: Indicates a less urgent issue. Flashing light or red: Indicates a severe problem that needs immediate attention.
Check your gas cap first. Many vehicles have a loose gas cap indicator that will be triggered before your check engine light comes on. If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light.
Low Oil and Check Engine Light
However, low oil pressure, which can be caused by low oil levels, can be a reason for the check engine light to turn on. Low oil pressure can seriously interfere with your car`s performance and disable your vehicle if not addressed immediately.
The yellow oil warning light comes on when either the oil temperature gets too high or the oil level or pressure is too low. If the oil is not lubricating the engine effectively it could lead to expensive or even irreparable engine damage, so it`s important to act quickly.
This is a sign you should stop driving and have your car looked at by a mechanic as soon as possible. Use your best judgment on whether to call a tow truck or drive yourself to a nearby repair shop. Is the light flashing? In many vehicles, there are two types of check engine lights—a solid light and a flashing light.
All the problems that could trigger a check engine light are serious. If the check engine light comes on, it`s one dashboard light you should not ignore. Whether for a week, a month, or a year, if you ignore the check engine light, it puts your vehicle, and by extension, your personal safety at risk.
A steady check engine light indicates a non-emergency issue, such as a loose gas cap. Flashing check engine lights warn of severe situations requiring immediate attention. Standardized diagnostic codes help identify the trouble.
However, failing to clear a code after a repair could leave you second-guessing the issue or doubling your work to recheck the codes. That`s why you should always make clearing codes an essential part of your repair process.
Sometimes, the check engine light comes on to let you know that there`s a problem with the car`s internal diagnostic mechanism. That means the system could be “finding” a problem that doesn`t exist, or it could be that loose wire systems are creating a false positive in the system.
If the check engine light illuminates, it will either blink or remain constantly illuminated, depending on the problem. A blinking light, or in some cars a red light instead of a yellow or orange light, indicates a problem that needs immediate attention. Either way, you should have the vehicle checked by a mechanic.
Another common cause for a check engine light to come on is low tire pressure. Not all vehicle`s are designed with a malfunctioning indicator lamp that will detect this issue, but most newer models do. Simply tend to your tire as needed, and the check engine light will turn off.
Oil filter that has become saturated with dirt not only holds the motor oil but also deteriorates its lubrication properties causing increased friction among the moving parts which is another reason why the engine might heat up during normal drives. It may cause the check engine light to come on.
Amber engine management light
This is an advisory warning, which indicates an engine issue that affects emissions. In most cases, you`ll be able to continue your journey, but you should get your car examined as soon as possible.
Clock some miles
To make sure the check engine light does not reappear, it`s recommended that you drive your car 30 to 100 miles. This enables the vehicle`s “Drive Cycle” to reset, as the various sensors need time to recalibrate.
A flashing orange light means that there is a problem that could affect how the car drives or handles, such as an engine misfire. You might be able to feel your car shake, or the engine could suddenly sound different. If this light comes on, you should take your car to be inspected immediately.
The simplest way to describe the difference is that the Service Engine light informs us of upcoming expected maintenance. On the other hand, the Check Engine light informs you of an unexpected problem occurring in your engine or exhaust system.
With the OBDII Scan Tool MS309 from OxGord, you can easily read diagnostic codes, clear trouble cods (DTC`s), and turn off the check engine light (MIL) on US based vehicles from 1996. It will also retrieve the vehicle identification number (VIN) on 2002 and newer vehicles that support Mode 9.
Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.
