Hello someone has also made bad experiences with the tire pressure sensors that are not original of Volvo. Had bought my from tyre dealers and after 2 months the error message tire pressure maintenance required. I to dealer and who told me that the sensors I bought from the tyre dealer did not communicate with the car. After some in and out between dealership and tyre dealer installed the original Volvo sensors, and the problem ( error message is gone.) wa Find that the dealership could have said yes that they had problems with Non-Orginal Volvo sensors. Then I could have saved myself the whole back and forth.
