I have a 1998 Audi A6 Quattro 2.8 that my husband brought for me last month on the 9th! But ever since we own it we never had any problems with it. But last month in May I came to Lawton Oklahoma to fix my car titles.... But while I was here my check engine light was on so I went to AutoZone. To find out what was up with my check engine light ever since they hook that thing to check my car! I have been having problems with it it want start I have to get out of my car! Lock the doors and then u lock them in order for my Audi A6 Quattro 2.8 to start! But now it's not starting but when I keep on trying to start it it will crank but will never turn on! Then after that it goes back to what it was doing before no crank no nothing just dead silents... Can anybody please tell me what's going on with my Audi before I destroy it with a hot and fiery passion!!!!!!

is it fitted correctly? If it is not fitted correctly it will do this. Have you checked the relay?

No sweat. This is a periodic reminder that your car is due for some sort of servicing, usually based on mileage. It may say "service oil" or "inspection" or some other indication along those lines. This is not related to a check-engine light, which tells you that you have something wrong with your car. The inspection reminders are manually resettable with the small stalks on the instrument cluster, and are meant to be reset each time a service interval is reached and that service is completed.

On my A4, the reset is this way: with the ignition off, hold down the stalk on the right, by the odometer, and turn the key on (don't start the engine). The display goes to "------". Pull out on the other stalk to reset it. Turn the key off, and release the right-hand stalk. When you turn the key back on, the indicator should be cleared. It may be different on your A6, but try it that way and see if that clears it.

My 2005 A4 3.0 convertible audi is not a diesel, but I had a similar experience with a low oil signal going on and after checking the oil, which was sufficient, and replacing the dipstick, the light did not come back on until a subsequent trip. The light usualIy went on when I was close to the needing an oil change. I've had the car, a used one, for about two years, and the oil light minimum signal started behaving like yours early. About a week ago the oil pressure warning light came on. I don't know if there's a relationship, but if there is be careful. Audis of our vintage have a problem with sludge build up that damages the oil pump, which is a costly item. If you drive the car with low oil pressure you may seriously/fatally damage the car. I don't know if the sludge, if that's what you have, can be cleaned out, but I'd do it if it can be. My mechanic advised me to trade the car to a dealer rather than fix it. Hope you have better luck!
