Very soon after mot had sensor fail test showed o/s/f so fitted new one warning off till short drive then on again so gave up thinking will try again when mot due anyway 4 months later I was very low on fuel with both fuel and tyre pressure showing but was only near a expensive station so just put 10 pounds in went down road and the gauge had not moved with both warning still showing after about a mile It stopped flashing and just stayed showing low fuel for short time then up came clock and warnings gone . Think it must had done a self reset ?

 

not sure if it helps, but I had an issue similar in a mustang that I had, where I had placed one of those transmitters that sent the music of a sdcard , mp3's and stuff into a FM channel of my choosing so I would be able to listen mp3 via FM, I found out that was disrupting the signal that the tpms in each wheel was sending to the car. maybe you experienced some temporary disruption?
