Hi, I have an odd case with a 2013 x5 35sd. The tpms will reset and shows green and acts like it is working, but doesn't work.

I've had one tire look flatter with no warning and it was in fact flat (0 lbs). Never did get a warning on it. I took it to the dealer and they said it was.

Today I took my all seasons off and put on the snow tires. The tpms showed green still with no reset or reprogramming which tells me it isn't. What can I do to test if it really is or is not working? How do I convince the dealer if it looks like it is but never gives a warning?

I don't want a flat on the highway and to not know. Any ideas?

Thanks!
