Driving today and the car made a beep sound

[JPHCCFC]

As if the petrol was low or a warning light was about to come on, though nothing happened and my petrol wasn't low! Anyone kknow what it might be. The fuel MPG status was on but that was it. I did a status check and everything seemed OK

very common - usually it is simply a communication 'blip' between the PCM and the transmission - more here - > http://www.lincolnvscadillac.com/showthread.php?t=49260

it's called the "mystery beep"

Both of mine do it a few times a year. Sometimes I was curious and pulled the codes. Each of those times, it was a momentary communications issue between the REM and the cluster.
