It could simply be maybe the person changing your oil never reset the light? or you have a oil pressure sensor leaking or not working.
most of the time its someone never reset the oil change light. even before it goes on it goes by mileage, so maybe it didnt go off yet cause you cnahged it a tad early.so noone even tried to reset it.
I guess you could have an oil pressure problem, but thats going the extreme route.. but if nothing else shows that could be a problem.

DON'T TRUST AUDI MANUALS, MY 2003 A4 PLUGGED OILS LINKS ONLY AFTER 5000 MILES. VW STRETCHED THE MILEAGE OUT TO MAKE A PROFIT AND I REALLY RECOMMEND 4000 INTERVALS, NO LONGER -AT A US EAST COATS TEMP RANGE OF FREEZING TO 10 BELOW TO 15 C - 20 C.
AUDI ENDED UP INCREASING OIL LINE SIZES AND ENLARGING THE OIL FILTER BY 50% AND TELLING ME TO USE THE NEW FILTER FROM THEN ON.
SO LESSON LEARNT, EVEN WITH SYNTHETIC, DO NOT GO BEYOND 4,000 OR BAD THINGS WILL HAPPEN -CALLED ENGINE SLUDGING UP

SOURCE: oil min. warning comes on,
this is just a thought , but i would first replace oil pressure switch as this is cheap start to solving your problem , i wonder if you have caused air leak when chnageing oil sensor in sump by not sealing sump correctly ,? the other thing may be you oil pump is worn causing incorrect oil pressure , which may be reason for your oil problems in the beginning , hope this helps , i know what its like when you run out of idea's good luck .

I would check to see if there is a level sensor in the bottom of engine oil pan. If there is not, there is also a oil switch that threads into the block that could be bad.

sludge could be causing the light to come on. most likely the sensor came on because you went a certain mileage without changing your oil.
