So bottom line is anyone who puts any kind of tune on their cars (sw, piggy back, paper clip , whatever)
has to understand they MAY have to cover costs for repairs and loose their warranties (if it's a lease car BMW can even possibly have you buy out the car as you breached the lease agreement)
True. Unless you buy a tune with warranty, as some of the German tuners does.
