It is a debatable question. You would lose the warranty if it can be proved that a change of setting is the cause of the degradation of a part. Example: change of settings to door openi
Gs, closing, tail gate closing, suppressing warnings, DVD in motion, displaying tyre pressures etc won't stress car parts beyond normal operations.
If you have saved your original cafd files, you can always go back to original settings. In such case, don't read the cafd file values from the car, use the original saved cafd files. There are other ways too but I prefer this over others as I know exactly what change I m reverting to and not leaving system to set the default values on its own.
