So I live in Texas...
 

Its really cold here (high of 26 low if 19)We have no idea what cold is in Houston. I think its like 30... Anyways, when I started up my 2007 A6, it took half a second longer then normal. Everything sounds and looks fine. Belt is spinning, no knocking that I can hear from the engine. Fluids heated up slowly, but all got to temperature in expected times. No overheating.

Now for whatever reason my check engine light is on. I had this car over a year and have yet to see the dreaded check engine light. Could this be a result of a random winter storm coming through, icing up our roads to undriveable standards, and freezing up a sensor? I did not drive it, simply started it, (trans temp was at 23 degrees) and let it run for 15 minutes to defrost windows, clear ice off of hood and do its cycle. I killed the engine and restarted the car... still shows the light. Thoughts?

No I cannot take it to an auto parts store atm for a diagnosis, I refuse to drive in the conditions my street was left in.

My recommendation is purchasing one of these just to have. Its a great tool

Well then ... You are going to have to wait until it warms up and you can drive it somewhere to find out what codes are set.

We can't diagnose a check engine light here if that's all that you have ... could be anything.

I am aware it can be anything. I do plan on diagnosing it professionally. My question is if its possible for the engine light to occur under cold weather conditions like this.

I can't see it being normal for cold weather operation ... There are some folks starting there C6s up north in much colder weather than you have there in South Texas.

I saw a guy driving a C7 here yesterday, it was 10 degrees.

At least yours started. Mine won't start. Tried to use my Stanley Jump starter, but it keeps saying it doesn't recognize my fob now... Cold weather sucks.

Can't be just due to weather. I start mine up a couple times over this winter (Indiana) and we have been getting -10 and I have not been getting any check engine lights due to weather.

the cold weather should not really set a check engine light.had to start mine a few years ago at -40F.no cel

Lol so being concerned over the weather affecting my vehicle means I hate the car? Really hoping this is sarcasm. Love the Corvette, been relatively problem free for a while, I don't understand why people don't just give a yes, no or maybe on here to simple question. "Does cold weather create a check engine light for C6 Corvettes." It wasn't a question on rocket science, but a question for (what I'm assuming) a group of knowledgeable long-time Corvette owners could answer in like 5 seconds. Jesus lol.

Okay, thank you this is pretty much the answer to the entire question. I appreciate you sir!

I'm no mechanic, but can assure you that I have started mine in very cold weather with no check engine light.

go to the Autoparts store and let them run the codes.

I drove mine last night in single digits, no problem.

BTW my CEL has been on for several weeks due to false EVAP code. I usually just discount the battery to clear it.

Can't be cold --- I drove mine in much colder conditions than that. Look further into the O B D

There is a procedure in the OM for that

Yeah, about 5 minutes after my post I was able to get it started. Cold weather must've caused a brain freeze, because I totally forgot about the glove box fix.

Update:
Temperature is at 30 and ice is melting away. Took the car for a drive and the light went off before I could make it to O'reilly. SOL, cant check the old history of codes now. This guy leaving told me he could check it though as he has one that can look through the history of codes and pinpoint the problem. But since its off, he said if the car hasn't been tuned then its probably just the 02 sensors. They tripped when the weather dropped by over 40 degrees and the car sat for over a day.

Long story short, my headache is gone. I will get him to run codes tomorrow for me when I am off work, but that seems to be the problem since I don't think the light would of just turned itself off without me doing anything differently.

Sometimes you can shut it off and restart it and the light will be gone.

Low of 19 is cold...How cute. :rofl:
