The engine check light is telling you that there is a fault with a sensor on your engine

you need to go to a garage to have the fault codes read from your computer

even though your car is running fine its a matter of time before it plays up

How do I turn off my check engine light myself


Likely won't be able to do yourself without a vag com I would suggest going to autozone or the like, they can read the code and see what the cause is. Most times they will clear it for you. This is a free service of autozone, advanced auto, etc. your mechanic may charge you $40 +/- to do this.

you can talk to someone a the dealer(service manager/tech)to see if they can reprogram the pcm so it recognizes there is no egr on this motor

The check engine light is flashing


Why Is My Check Engine Light Flashing? Location
  1. The check-engine light may be a graphic of an engine or similar icon, or it may contain the words "check engine" or "service engine." In some vehicles, a red check-engine light means the car needs absolute immediate attention while a yellow check-engine light means you need to make an appointment soon. Either way, you should know the location of the light and periodically glance at it to ensure its status. The light is used to indicate power train problems that are associated with your vehicle's emissions system. (The power train is the engine, transmission and other power parts of your vehicle.)
Flashing Light
  1. Typically, a flashing light is more serious than a solid check-engine light. The flashing light is meant to alert you that you may have a misfire in your engine that will cause catalytic converter damage if you leave the problem unresolved. Replacing a catalytic converter can be costly, so have the engine checked as soon as possible by a certified mechanic.
Cause
  1. A flashing check-engine light generally indicates that there is a failure in the emission control system. The emission control system contains an array of sensors that work to reduce the amount of pollution released into the air. An oxygen sensor reads the air and fuel mixture and lights up when it is out of range. The acceptable range is between 50 mill volts and 800 mV. If the check-engine light is flashing, you should visit your mechanic or dealer as soon as possible.
Loose Gas Cap
  1. A gas cap that isn't twisted on tight enough may cause the check engine light to illuminate, but it won't flash. Try tightening the gas cap and watch the light. In many cases, it will turn off because the problem has been corrected. If the light stays on for more than a day or two, have your mechanic run an on-board diagnostic (OBD) to see if there is a code in the system indicating a serious problem. Your mechanic can reset the light to off if the problem was a loose gas cap.
Spark Plug Wires
  1. As spark plug wires age, they can become brittle and crack, causing an electrical misfire. Your check engine light might turn on and stay lit. If this happens, go home as soon as possible, turn off your engine, and inspect the wires. If the wires are brittle and cracked, you need to replace them. If your check engine light stays on after the wires are replaced, have your mechanic run an OBD.

2001 vw jetta gs :check engine light goes on and off


sounds like a faulty sensor tripping and reconnecting.. the next time the light comes on, take it to an advance auto store or an auto zone, they can read your codes for free... this will tell you what is being tripped, that way you know exactly what you need to get checked and/or fixed instead of a mechanic poking around trying to find everything thats NOT wrong. but if you are not expeiriencing any difficulty with the car, you should be fine. the check engine light actually means alot less than most people think. its usually a transmission or emissions sensor, or even as simple as leaving your gas cap off after filling and then driving for awhile.
