on my 2011 A4 the MMI doesnt display any oil level after i added some oil (my oil level reading was below half - i added .5 liters), i have driven the car for 3 days now (more than 50 miles) and still the MMI says "there is no oil information available at this time" is there any way to solve this ?

Looks like it came back, after driving for 3 days. Quite weird.
