Pietersen was dropped in August for sending "provocative" text messages to South Africa players.
A statement issued on behalf of the 32-year-old claimed he had apologised to ex-England captain Andrew Strauss and also met new skipper Alastair Cook.
It also denied Pietersen had offered tactical advice to the South Africans.
Discussions between Pietersen and the England and Wales Cricket Board have been ongoing since the second Test against Proteas at Headingley, when the Surrey man himself cast doubts on his future.
The batsman subsequently backtracked on his threat to retire from international cricket, but the texts he sent to South Africa players, which allegedly criticised Strauss and reportedly gave advice on how to get him out, ensured he has not played for England since.
The statement from the Pietersen camp was issued shortly after the squad for the tour to India was announced.
"At all times, Pietersen had wished his dealings with the ECB to remain private so as not to inflame an already difficult situation," it read.
