Thanks for the comments/observations---Perhaps I did not make what is happening very clear in my first post-----the locking pump(I have verified it is the central locking pump), after driving , I stop, turn engine off, remove key, then open door to exit, you hear the pump run for 5/6 seconds. The pump turns on, runs ---have not pressed any button on fob. Pizza Guy I believe mentioned that the pump would only run if activated by the lock/unlock dash switch , or key fob buttons.. My concern is that this does not appear to be normal operation--PROBLEM ???
