You have the earlier system that uses data from the ABS to work out if pressure has dropped (rather than the later system which has sensors on each valve) by comparing revolution rates across all wheels. Sometimes you may have to do the reset more than once until it stops nagging you.

Do you have the same tyres all round as differences in tyre wear (such as new on one side, badly worn but usable on the other) could also give a warning?

Ah right, you only get two goes at resetting it yourself before adjusting the pressure. After that, it detects rogue resets just to stop the warning at which stage, only the dealer can do it.
