I purchased a set of wheels for summer use, keeping my stock set as winter use. So ordered MX sesors, for the summer set up. I had read previously they need to be woke out of the wheel. So activated them before having the tire mounted on the wheel. Put the wheels on go to relearn. The TS508 finds all sensors and does the whole ECU rewrite, drive for the 10 mins as recommended. Go for a drive later and about 20 mins tire pressure light comes on. Check the diagnostics it said transmitter error sensor 1 2 3 and 4. All sensors were still showing as connected, so tried the relearn again, same issue.

So finally I try a firmware update, Now the ts508 can not find my sensors at all. How do I get these to works? so far, its just looking like a waste of almost $500!
