My brother has a 2018 540iX and has an error on the dash about a TPMS sensor so I bought the Autel TS508WF reader to confirm the issue. I figured it would cost more than the cost of the unit (about $250) to bring it to the BMW dealer and have them tell me I need a new sensor or two than to buy it and have them replaced myself. It turned out he has 1 dead sensor and 1 low battery so I checked my 2019 M5C and was surprised to discover that I have 4 low battery levels in mine. The good Autel sensors from Amazon are about $30 each vs. the cheapest discount BMW one I could find was $91 so I bought the Autel ones and will have them installed this week. The Autel tool can properly code the sensors as they are dual frequency and program the car if that needs to be done.

If anyone wants to bring their car (BMW or any other car) by the Upper West Side in NYC, I would be happy to scan it for free - it only takes a minute now that I own the tool.
