I'm worried that the MMI reading may not be working properly so no real idea what is in the sump. It was at max before I changed the oil and put around 0.5L less in than I took out but MMI still says max. I really need a dipstick.

Came across this video using OBD11. A different model and year of Audi, but worth checking:

At least you're aware that the MMI range represents 1 litre, but worrying that a 0.5 litre less seems to have no effect. From what I've read, they also seem to fail in various ways, from permanent low oil to permanent overfull, and they don't seem to throw any sort of error code.

One comment I saw was someone with an issue, and they said that the MMI was showing full with the engine off, and dropped with the engine running, and back to full after engine stopped for a while, which would seem to at least indicate that the sensor was working. Have you ever noticed this with yours, as if it does, it would tend to indicate that the sensor is working properly (in theory).
