LOL - What a difference one word makes. sorry meant to say.
However, I was really looking for a response from an Audi owner who has the same engine and is actually using such a dipstick, with those measurements.
Just to update. Cars been into the garage today for full service and to sort out the problem. It was sticky/ ceased callipers In the end. So a full new front set of brakes yay. Fingers crossed all sorted now.
