fuel gauge

[blue metal]

just let tank empty until fuel light
came on  (595 miles) for first time
it went to full as normal on fill up
today gauge zeroed while running
I had used the heater control 1234
and then gauge returned to full
minutes later zeroed again
still only one fault on vcdi
temp sender
have not found any similar faults in search

any suggestions

See if it does it again any time soon, the clusters are known to do this occasionally (some sort of software bug) so just keep an eye on it for the minute...
