Question about 2005 Volkswagen Golf
Volkswagen vehicles built after 1996 are equippedwith a system of sensors known as On Board Diagnostics (OBD II). These sensorsmonitor many vital engine functions and help to lower harmful emissions. Whenone of these sensors fails it sends a signal to the engine computer to illuminate the "CheckEngine" light in the dash. To clear this light you will need a diagnosticcode scanner. Scanners range in price from $40 to $120 and are available atmost auto parts stores.
1. Connect the diagnostic code scanner to the vehicle's diagnostic port. Theport will be located in the dash below the heater controls.. 2. Turn the key to the"Run" position, but do not start the engine. 3. Press the button on thescanner that reads "Scan for trouble codes." 4. Wait for the scanner to finishscanning the engine's computer. 5. Press the button on thescanner labeled "Clear all trouble codes." 6. Disconnect the diagnostic codescanner from the vehicle.

I had the same problem, took it to the garage and they plugged it in to the diagnostic computer. I had just had alot of work done to it and there were about 8 different problem codes that came up on the computer. The mechanic cleared out all the problems, had me drive the car for a day or so until the light came back on. He hooked up my baby to the computer again and found only one problem. The O2 sensor was bad. The part cost about $200 from VW and $100 labor. Light has been off since. Being that the light could mean many things you definitely need to have it hooked up to a computer. If there are many alerts on the computer i would suggest doing what my mechanic did so that you're not spending money on someone fishing for the ultimate cause. Hope this helps!

You need the OBD codes checked to be certain of the problem. If engine
is running ok with the light on, it may well be an oxygen sensor
