Check Engine and Air bag lights
The "check engine" and "air bag" lights are on in my car. When the check engine light came on and stayed on, I took it to a mechanic. They ran a diagnostic which said "call manufacturer." After playing phone tag with a VW dealership, the mechanic told me it was an oxygen sensor. (Do I have two because I had replaced one before this?) So after $300 and a new oxygen sensor, the damn thing came back on. What gives? As for the air bag light, it just came on and stayed that way. Out of curiosity, the mechanic tried to get a reading from the diagnostic for it but got nothing. So on it remains. I havenever deployed the airbag. What are these lights doing on? How do I turn them off?

RE: Check Engine and Air bag lights
My friend had the same exact problem in his Jaguar but after he replaced the Jaguar oxygen sensor it was fixed immediately... Maybe your mechanic made a mistake in installing yours... With regards to your air bag light here are some instructions that a friend of mine gave me when I turned off the air bag light permanently...
1. Connect two wires long enough to reach the ground/floor to terminal Tc and AB of the TDCL port. The TDCL port is located under the driver's side right above the parking brake. The blue wire is connected to terminal Tc and the red wire is connected to terminal AB.
2. Connect a wire long enough to reach the ground/floor to a grounded point on your car. Connect this green wire to the bolt that holds the driver's side courtesy switch on using an alligator clip. Just lift up the bottom section of the rubber cover to see it.
3. Turn the ignition switch to ACC or ON and then wait at least 6 seconds.
Now you need to do what I call "the wire dance." You're going to alternate touching the ends of the Tc and AB wires to the ground wire. Let the ground wire lay on the floor then you can easily touch the Tc and AB wires against it. 4. Start by touching the end of the Tc wire to the ground wire for one second. After a second, instantly remove the Tc wire and replace it with the AB wire touching the ground wire for one second. Now instantly replace it with the Tc wire for the 3rd second, then instantly replace it with the AB wire for the fourth second. Finally, instantly replace the AB wire with the Tc wire and hold the Tc wire on the ground wire for several seconds. After several seconds the air bag light will blink fast in a 64msec cycle, this means code 41 has been cleared. So if that didn't make sense here's the short version:
Tc + ground, AB + ground, Tc + ground, AB + ground, Tc + ground and hold.Hints:
-This is all about timing. When touching the wires for one second you have a plus or minus 0.5 second margin of error (so you need to hold the wire 0.5 to 1.5 seconds); this means you don't need to be exact. Just count slowly "one one thousand," after that you instantly switch the Tc and AB wires.
-Instantly means instantly. You only have 0.2 seconds to switch the wires. So right after you remove one wire have the other wire touching. Instantly. If you don't switch the wires fast enough the air bag light will blink out a code 41. A code 41 is 4 slow blinks a little space and then a fifth blink. If you get the proper timing the air bag light blinks really fast and then the light goes out.
-If you don't get it keep trying. This procedure will took you at least ten tries before you find the correct timing. You don't need to disconnect the wires from the port either, just try the wire dance again.5. Once the code is cleared disconnect the wires and close up the TDCL port. Then it is doen...
Good luck!!! Hope this helps....

RE: Check Engine and Air bag lights
Eeek I hate that dang air bag light! My 05 beetle had that light on constantly. We had to take it to the nearest VW dealership which was 50 miles away to get it turned off. They basically told me it just came on for no reason and not to worry that it wasn't a big deal. Kinda made me feel unsafe I'm sure yall would feel the same way. But now I got an 07 beetle last week and no probs yet haha. My 05 beetle was knew when we got it and CRAAZY. Heh I like to say my bug had a bug.
