I have my tyre pressure alarm on after I drive shortly and after SOS alarm also I ve no reset in I drive under settings also all tyre pressure is ok front and rear I think I ve rotational abs sensor but no abs alarm what is this?
BMW uses two types of tire monitoring systems depending on build date/model year (which you didn't identify). One is an indirect FTM (RPA flat tire monitoring) system which uses the wheel speed sensors...and a direct TPM (RDC tire pressure monitoring) system that uses sensors in the wheels that send data to the RDC control module which then sends the data to the iDrive.
If you have the indirect FTM/RPA system...the instructions on how to reset the system once low air pressure has been detected should be in your owners manual. If you don't have one...try a simple google search for your model year BMW owners manual PDF...you can then download it to your CPU or other device where you can have access to it anytime you need it.
if you have the direct TPM/RDC system....the reset instructions are also in your owners manual...and iDrive should also give you some type of instructions on how to reset the system once you've re-inflated the tires or changed a wheel etc.
