I purchased an Autel TS508WF which came with 8 metal body stem MX-sensor-1 sensors. They were the adjustable angle version which means the sensor body can pivot slightly then tightened to accommodate steel and aluminum wheels that have different contours I suppose. I received early Nov for slightly less than $300USD delivered. As previous posters pointed out, Autel sensors need Autel scan tools to program their own blank sensors. If your shop doesn’t have the Autel scan tools to program, this may be an issue. The only way to use another mfg scan tool is if the Autel sensor already has been programmed with a unique ID flashed in. I have not seen preprogrammed Autel sensors for sale new but just pointing out if you bought used wheels and know Autel is installed for example. Then you can relearn the four sensors into the vehicles ECU module so it knows what to look for. This goes the same for the Autel TS508WF tool where if you replaced one bad sensor(s) with a non-Autel sensor that ALREADY has an ID flashed in, you can relearn position and match all four or maybe five with applicable spare tire application to the ECU. What Autel can’t do is program or create/write IDs to non-Autel blank TPMs sensors. That goes the same for non Autel scan tools can’t program or create/write IDs to blank Autel MX sensors or at least I am not aware of this.
I had an issue which I believe is about to get resolved with some support from customer service but overall, I don’t regret this investment only because I have three vehicles to take care of and the cost/vehicle goes way down upon usage. Secondly, I have access to a tire machine and balancer so it took me like 45min/wheel from jacking up to jacking down. This may be a game changer for DIY that wants to go this route because it’ll be a big pain to do this. My OEM TRW TPMs sensor was almost exactly 1/4 oz heavier than the Autel MX sensor so I didn’t even bother to rebalance as I don’t feel any highway vibrations so don’t care.
