      I have a 2002 Jetta 1.8T, and a light on the dash that looks like a triangle with a circle around it, with an exclamation mark in the middle, is showing up every now and then (i think this symbol normally blinks if the car is sliding)... Its the triangle symbol in the below pic:

      Anyways, after driving, this light will come on (steady, not blinking). Does anyone know what could be causing this?

      I did recently have some CELS being thrown for a bad front 02 sensor and bad temp sender. I had those fixed, and the shop also fixed an exhaust issue (hangars that hold it up broke). I still have a CEL for a checksum error from my ECU/APR mod, but not sure why this other light is coming on.

      ???????

      Traction Control light

      If tires start to break traction from the road, it will blink, letting you know, and also pull some power to regain the lost traction.

      If the light stays on, then either you turned it off, by pushing the ASP light i believe its called near your ac vent, or you have an issue with the car and it is automatically dissengauging it.

      My Jetta had problems and the traction control never worked.

      So, if you are trying to launch the car hard peeling out, or doing burn outs, or anything where the tires might breaks loose(if thats what you want), turn it off...

      It's just a safety feature...

      Well that light is your traction control light. Check your MAF, cause i forgot to hook my MAF back up one day and the light would stay on.

      the shop replaced my front 02 sensor, and did some exhaust work...would they have had to disconnect the MAF to do any of that work?

      How do I/where do I check to make sure MAF is plugged iN?

      Your MAF is connected to your airbox. So when your looking at your engine on the right side should be your airbox. Connected to that is a round device (MAF) And that has an electrical plug that should hooked to it. The MAF then connects to your intake pipe (rubber hose about 3in around) that runs down to your turbo by the firewall.

      I did a quick search and found this pic. The MAF is between the 2 red hoses. And the connector on the back of it is what needs to be there. Your set up will look a little different but its not hard to find.

      could it be that I have a bad MAF? I'm guessing I would be throwing a engine light for a bad MAF if I did, right?

      Not sure what the MAF does, but don't some people run their cars without the MAF?

      My mom's tdi wagon does the same thing...

      Would wheel alignment have anything to do with it? Cuz that was my guess... maybe it is the maf though?

      I havent heard of people running without a MAF. Running without a MAF would make for some bad gas mileage and not running very well. The MAF tells your computer how much air your getting.

      But i've heard of that light coming on if the MAF is bad. But get stuff check out before you spend any money.

      You can try to unplug your maf and see if it runs better. I believe the ECU can compensate for it being unplugged. FYI, it will make the light stay on as long as its unplugged.

      I have had issues with the ASR light before when my APR Tuning was fighting it out with a bad MAF.....have you had any problems with your car going in and out of "limp" mode?

      I'm not an engineer, however, I think the mean by which the ECU compensates is the MAF sensor.

      Anyway, in the past, I also had the traction control light stay illuminated. A few hundred miles later, my ABS light stayed illuminated. If I remember correctly, I had my neighbor clear the codes for me and the lights haven't come back on.

      I remember now. I think I simply pulled the fuses from atop the battery, cleaned them a bit, and then replaced them. Try doing that.

      you ass. i already said that it was the traction light... but it usually blinks when you lose traction. In my case, its a steady light when I am driving in normal condition at a normal speed.
