i received a post card today from VW that says my car needs a software update to improve the TPMS.
VW TPMS Recall 45J6 (US)
link to TSB --> Volkswagen TSB 45J6
description: "In a test environment, in rare cases, the tire pressure monitoring system may not detect an air pressure loss in the time specified in the NHTSA FMVSS No, 138 “Tire Pressure Monitoring Systems” test procedure if it occurs simultaneously at the same rate in all four tires. A sudden loss of pressure in all four tires at the same time that goes undetected as required by regulations increases the risk of a crash."
corrective action: "Update the TPMS software."
i scheduled for 31MAR2023 and will report how it goes.
