Toure made the claim in an interview with France Football last year.
He has since offered an unreserved apology for his actions. It has so far gone unanswered and he is unsure whether the apology ever reached Guardiola.
"That interview was my big, huge mistake," Toure told the Daily Mail. "When you give your trust, your voice to someone, they can twist it.
"I was aware some staff were not happy. I emailed a letter to try to communicate with some important people there to apologise and say I've been indecent to the club but I haven't had any feedback.
"I want peace. We don't want this (acrimony) all the time. For the love of the fans, for the love of the club, sometimes things have to be settled the right way. I've been in touch with some people there."
