No way to know for sure without taking your car in to be checked out.
I'm aware that if the oxygen sensor goes bad for some reason, the check engine light comes on. At work this happens on the Malibu's in our fleet when the rodents chew on a wire when the car is parked in the lot overnight in the same space for a few days. For some reason, they go after the Malibu's and ignore the Stratus vehicles we have.

I had the same issue with my 06 A4 Avant. Traction light would come on an over-ride the engine. The dealer tried to fix the car several times but failed. Finally they said they placed an order for a new PC board that controlled the engine. They needed to get this direct from Audi in Germany and was made for my spacific vin number.... Worked like a charm. I have not had any issue since then.

I have the same "problem" with my new 2008 Audi A4 2.0T Quattro. Lots of Slimey Black Soot in the exhaust. Makes a big mess trying to wipe down the tips. When it's wet...it splatters all over the back of the car. Why is this happening? This can't be good for my Catalytic's. Is anyone at Audi aware of this? I Went to the dealer...they told me I had "Bad Gas" and to refill with "Shell" Brand gas instead of the premium "BP" gas that I was currently using. I have never heard of this. This has to be a joke. I seem to be getting a lot of "Bad Gas" these days and it 's nothing Beano can fix!

They weren't joking about the "bad gas." Some brands have additives which will help prevent the very problem you describe. Brands such as Shell, Texaco, Chevron, and Conoco are good. Avoid Mobil/Exxon and BP. Google this issue about gas. It's not just Audis which are affected.
There should have been information provided when you bought your car. With the other owner material was included a list of good gas brands. I already knew about it and have been careful about the gas we put in our other car--a Saab.

Aug 03, 2008 (4:45 pm)
I recently took my Audi to the dealer for the 40K scheduled maintenance. I have maintained this car regularly & have had no problems with the vehicle until AFTER the 40K maintenance.
Earlier this year, Audi sent me notice of a fuel pump recall. The dealer inspected the fuel pump & said it did not need replacing. They charged me $689 for the 40K & sent me off warning me that all the brakes had to be replaced within 3 months.
Then, two days later I had to return the car to the dealer when all the gas leaked out of the car as I was filling it up. The dealer ended up replacing the fuel pump after all even though they supposedly had just inspected it & found nothing wrong. But, even then, they tried to argue that they were not at fault! I argued my case & ended up with free rental car for the 4 days it took to order the pump & fix the problem that supposedly wasn't a problem.
Now, one week later, the engine light suddenly came on & the car abruptly started running rough - VERY rough. I managed to get the car back to my house although I was nervous driving it. Once again I called the dealer who then cited numerous possibilities (along with the cost for each possibility) such as a failed catalytic converter (cost = approx.$1,500). Of course the dealer failed to mention how the recent poor maintenance (incident #1 & #2) might be a factor.
I had no problems with this car until after this 40K scheduled maintenance. Then a host of problems cropped up. I have two questions based on the above: (1) Can I drive this car back to the dealer without worrying about engine damage or should I opt for getting it towed?; (2) What are the probable causes of ENGINE LIGHT ON + ROUGH ENGINE following a "heavy" maintenance?
Thanks so much for any help you can give to me.

It sounds like a bad coil-pack on your car. Typically on Audi's when they go bad it results in the behavior your seeing. This can be checked by a relatively simple scan tool at most auto parts stores. If the code shows a bad coil pack it may not show what cylinder but there are ways to determine which relativaly easily.
If you do a searc on the web for "audi coil pack diy" you'll likely find the best method.
Your car is just about the right age and mileage for this to happen and it's not uncommon at all. Just poor timing.
PS - that dealer sounds like a nightmare, you may do better finding a good independent shop in the area that specializes in German vehicles VW/Audi in particular. There are lots of them out there.

It was a rough engine after replacing the spark plugs in my case. It ended up that they needed to replace an engine coil - probably same as mentioned in another reply. they told me this sometimes happens after replacing a spark plug. Driving the car should be OK if it's just a small distance to the dealer.
#1825 of 2367 Power windows
Aug 11, 2008 (5:50 pm)
I just bought a 1999 A4 quattro this morning and the power windows quit working for me! They worked on my way to lunch but when i got back into the car they didn't work at all. the sunroof doesn't work now either. It still works to open and close them with the key in the door lock but thats it. Any idea's as to what the cause of this might be?

This is a duplicate question which has been addressed already in the "Transmission Traumas" topic.
