These TPMS sensors are the original sensors used on 1.5 Roadsters (2008).

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.  Although only one sensor fails at a time, it is a good idea to replace all 4 since the others are sure to fail soon as well.

Replacement is the only option since access to the batteries in each sensor is not possible.  These are brand new items in factory boxes.
