It's telling you it needs to be changed. You can reset it. See

I would say it's telling you to get the oil pressure checked!
When my oil warning came on (only at high revs > ~2800 rpm), I was told by the local mechanic that it was very likely an electronic fault. ("If you can see the oil on top and it doesn't heat up, ..."). He wasn't able to check the pressure himself.
Eventually I drove to the audi dealer about 20km from us. It was the oil pressure, but it was too late :-(
Luckily, I found a very good condition engine on a scrap yard, but it seems when they put it in all pipes around the engine desintegrated plus an engine mount. In the end I spend almost as much on this as I did to buy that car in the first place ...
I would say better get the pressure checked right now!

P.S. I did learn a lot in the mean time: For some reason, they have two sensors on the engine:
- One gives a fault if the pressere is below 0.3bar
- The other gives a fault if the pressure is below 1.8 bar, but the autocheck system only complains if the engine refs with >2800 rpm. This made me believe that I only had a problem when I went fast. However, the other sensor was probably broken. This is indicated by an oil warning before the engine is started. However, I was used to cars where the oil lamp always comes on before the engine is started, so I didn't worry about that. I know better now.
Therefore: To all with autocheck systems, if the oil warning comes on before the engine is started, and then goes off again, it might be a faulty oil sensor.
