I have a 2006 BMW X5 4.8is. The TPMS light in the dash goes off when driving for about 45min at Hwy speed in 90 degree heat... I checked the tire pressure after the car sat overnight. The front is set at 32 and rear at 34. I reset the TPMS several times. After the car sits for a while the light goes way and doesn’t come back on until it is driven for an extended time at Hwy speed again. Any idea what is wrong????
Thanks a lot,
