I do not know a single person loosing the warranty because the car has been chipped. I am repeating what I have said before - this is completely invisible to the dealer if you disconnect the box. If you have fuel mapping program changed (chip tuning) again you do not have to disconnect anything and this is as well invisible to the dealer.
