These TPMS sensors are the original sensors used on 2.x Roadsters, VIN 501 on up.
TPMS sensors are installed in each wheel to monitor tire pressure and alert a driver more air is required for safe operation. When they fail, the Roadster firmware sends “TPMS Error” alerts to the VDS screen periodically.
Each of the 4 sensor contain a non-replaceable battery, which is good for 5 years or less. This is a set of 4 TPMS sensors.
Replacement is the only option since access to the batteries in each sensor is not possible. These are brand new items in factory boxes.
