Engine light should i be concerned? 02 jetta gls 1.8t auto 50k?
Always be concerned when an idiot light comes on. Take the car to determine why the light came on. If the light is red in color, tow the car or get someone to diagnose it where the car is at. Do not drive it because you can cause serious damage. If it's amber/orange you can drive it, but get it looked at to prevent further damage. Amber lights can also mean a sensor has stopped working properly which will cause inefficiencies.
The check engine light is for the emission system. Most likely its an oxygen sensor gone bad. Common on this car. Have it checked as if you let it go to long you may net to replace catalytic converter.
yes if the engine light comes on and stays on there is most definitely a problem have it checked out asap before it damages other components it may be just a simple fix or it could be a very costly repair you have to weigh the options Ive had several cars that weren't worth spending the money to repair them you have to decide you may have to fix one problem to find another so don't be surprised if you have to replace one part right after another good luck
