They allow you to track your efficiency performance over different distances and purposes. For example, I use the Driver Performance app in Sensus to track the lifetime fuel efficiency on our T8. It’s great since it also shows the last 1000 miles (I have it set to 100mi increments) of fuel efficiency and kWhr efficiency. The total number for me (the equivalent of your 11.8l/100km) is the average over 44,000+ mi at 48.4mpg. While I use the DIM’s TM average to track each tank fill up and as someone else stated the TA is the average over a 4hr period. It’s a more immediate although I sometimes scroll through the DIM menu to monitor the real-time fuel efficiency. Yes there’s a 4th option to see current/real time efficiency.

Thanks all for the explanations, all I really want is total avg and maybe sometimes real time consumption which is all I ever got on my 5 series ....lol was happy with that for about 15 yrs

Simple - use the Driver Performance App in Sensus for your lifetime total average and in the DIM scroll down the menu settings for the real time consumption to be shown under the Tach/Power dial. If you're not sure how it's in the manual too.
