Question about 2004 Audi A4
My check engine light came on this morning, and I'm not sure why. I don't have any codes yet... it just happened this morning. Nothing obvious began to happen when the light came on. Should I avoid driving my car?
I did check out some other posts, and it sounds like it's probably a sensor. I did see a previous comment that sounded familiar... about the temperature gauge. I had noticed before that the temperature gauge was doing strange things... it would go all the way down to 'cold' and then jump right back up to operating temperature again, and then it would repeat this several more times. Fluid levels are fine, and it doesn't do it all the time.
Is this something quirky, or is this an indication that my temperature sensor is goin?
Good chance it is temp sensor, but have the codes scanned and that will tell you for sure. Another sensor I have run across could be oxygen sensor, sometimes they will make the vehicle run bad and sometimes they dont but in either case is does affect fuel mileage. Dont think either way you need to avoid driving your car unless maybe temp sensor showed overheating problem. But dont wait too long to get code scanned.
