I guess if the stat was faulty the temps would be even lower especially when cruising at high speed as the radiator is being cooled.
The 88c figure might have been for older cars, unless there was a change in the thermostats in the newer vehicles.
My mates M4 runs at 79c and that is the range for M motors.

The N57 engine does not run below 88c once fully warmed up and heat soaked if the thermostats are working correctly.
How long are your journeys that you are monitoring the temps on? .. Have you tried monitoring the temps through the hidden menu rather than the phone app? I’m just wondering if it’s reporting the correct temp on the app or not.
