Run Flat Indicator Active

Could it be just that the system has been reset and only now reports that it has become active? The new Siemens system takes quite a few miles (even tens) to activate. You don't seem to have a lot of miles on the car, has the message been there for a long time? Does it pop up again even if you acknowledge it?
ive reset it many times but it still stays there. im 97% sure the warning was never there when i got the car. i just noticed it about a week ago and dealer claims its normal.
But then why do you have a spare if your car is equipped with run flats ?

Do I understand right that this message appears repeatedly? I don't find you stating you have cleared the message (acknowledge for the car) Perhaps a result from specific version coding.
i have reset it many times but nothing changes. the reason why im confused is i think it means run flat indicator active as in its detected air loss

My problem is that i cannot get to that screen. It ia supposed to be a submenu of the main display, but i cant seem to find it even though it is in the owners manual..
I guess I am just stupid

Does anybody know if this thing might be disabled, or was it optional equipment? My car had run flats when new, but the second set are Conti Contact3 which as far as i can tell are not RF. They do not have the "MOE" code on the tire only "MO".
Could the dealership have turned off the TPM when they installed the non Run flat tires?

Later versions use pressure sensors on valve stems that send radio message to a receiver under the car.
