Review on 🔧 Autel MaxiTPMS TS508 TPMS Relearn Tool, 2021 MX-Sensors Programming Tool (315/433 MHz) for TPMS Relearn/Activating All Sensors, TPMS Scan Tool for Reading/Clearing DTCs, TPMS Reset (Upgraded Version of TS408/501) by Brent Rosecrans

Worked correctly. It's easy to use and does what it's supposed to. I used it to see which sensor failed and activated the spare sensor for the car to recognize. Also activated are the new VDO Redi sensors, which are semi-universal replacement sensors on a new wheel and tire set. It quickly reads sensor data (ID, battery status, PSI). It activates the new sensors and should also test the key fob and key transmitters, although I didn't test this. It is not intended for programming replacement sensors that require an identifier to be programmed into the sensor. So it seems to do everything to directly replace the sensors and VDO Continental (semi-universal) Redi sensors. This is a Chinese company with very good support in the US. However, the question remains as to how long they will support this model. The initial software update is free but I don't know how long it will take. jay
