After the Buddha's enlightenment, did he receive any teachings?

There's not much background to this question. Did the Buddha ever receive a teaching after his enlightenment; a teaching that he accepted and made use of, either his own or another - or perhaps a teaching from another being other than a human. Please provide sutta references. I'm asking because of this term commonly found near or at the end of suttas: *'the job has been done, there is nothing more for this world'* Another way to put it: can one be independent of the teachings? If not, what situations would call forth the remembering and practising of the teachings for an enlightened mind? Thanks **ADDITIONAL EDIT:** In my quest to answer this question I had found a sutta in which the Buddha had asked Venerable Mahacunda to give him a teaching on the enlightenment factors. You can read it here. Also, the second part of the question is answered here which references this sutta here.
