Tire pressure psi
The OBC (noniDrive) has an options to switch units (e.g. kPa, PSI, etc), presumably for tire pressure...yet this value is not displayed anywhere (not even when low tire is triggered. Is there a way to code the BC to view this data?

So the phrase "druck" means pressure in German... I have found the following related entries:

Thanks buddy,
It seemed clearly designed to have a readout. There is a picture of a tire and a psi/bar/ipa option. Could it have been abandoned in development? What about auswertung_b_druck. What is that?

I don't know what it is, but you can try to active this, you won't brick anything, don't worry.

Could it be an option for including recommended tyre pressures?
As far as I was away the TPM doesn't measure pressure it looks a changes in wheel speed and can detect if a tyre is low. Or maybe I've been misinformed...

auswertung = evaluation; I'm still not sure what that value means
I too would love a direct psi readout but I don't think anyone has ever found a way to make that happen.

I personally hate that a pressure sensor goes off but won't tell which tire.

I have it coded on my F25, I have not looked on my E93 for it, you would probably need idrive and you definitely need TPMS, the rotational sensor don't have the data.
This is was it is on the F25 to turn it on to show pressure and temperature for each tire. HU_CIC 3001 EXBOX RCD_SAFETY aktiv/werte=01

My last company car had TPMS on the road wheels but not the spare, that's kind of dumb if you think about it.
