2004 A4 OIL PRESSURE LIGHT, not sludge, not sensors, what is it?

I have a 2004 Audi A4 Quattro. My oil pressure light indicator is turning on completely at random. At low RPM's, High RPM's, on the highway, on the streets, and at complete stops. When the light pops up, I push the check button, and it says to turn off engine and check oil level. Everything checks out ok there. So I have took it to the Audi service center. I had some minor sludge issues, but have now been corrected. That didn't fix the problem. Then they changed the oil pressure sensors, but that didnt fix the problem either. They told me that the rod bearings had a couple of scratches on them, and that could affect the oil pressure. They changed them, now I have not got the car back yet. But I was wondering, what other possibilities are there for the oil pressure light going on? The engine makes no funny noises and sounds very healthy.

wow, this is kinda confusing. I'm almost wondering if there is some electrical issue between the sensor and the ECU. Could be triggering the warning? I have no idea where to go with this, could mention it to the dealer I guess.

Well I got my car back from the Audi Service Center, turns out it was the rod bearings. Runs great.
