The PN listed for the S5 by a5sport is incorrect. The number he listed is for the S5 Cabriolets with the V6 S/C engines. The correct PN for the V8 S5s is: 079 115 611 AB (was 079 115 611 AD).
The procedure I go with when checking with MMI is: 1) Before shutting the car off after it is in full operating temperture, I let it idle for ~5 minutes first. 2) Turn the car off and wait between 2-5 minutes. 3) Turn the car to "On" without starting the car, then check with MMI. So far, the system has been working accordingly. But FWIW, I bought the oil dipstick before I even took delivery of the car as I don't have a lot of faith in the MMI system.
