I loused the warranty 5 hours after pickup the car from the dealer .
Using the Bimmercode app to enable or disable some function that aren’t in the optional you payed to BMW is the same .
To unlock DVD in motion is forbidden from the law and from BMW . To disable start and stop same .
Changing the shock absorber with some performance KIT or the spring . BMW say , you have modified the car from O.E SPEC . You lose the warranty.
Installing a spacers KIT ( forbidden from the law In Italy and EU ) and after having some issue on the control arms or bearings BMW say : " you modify the car from the original SPEC and you louse the Warranty "
Any modification made and not authorized by the manufacturer is equivalent to losing the warranty .
An ECU remap is more serious than modifying other parts , but for sure, an issue on some parts not involved on the engine or some other components will be on warranty .
This is my personal opinion .
In Italy , exhaust , brake rotors – brake pads etc etc are wearing parts and you can change with some aftermarket parts without lousing the warranty . They must be omologate .
You can do the service by your self during the official warranty , you must use quality aftermarket spare parts . This is Italian law .
Sorry for my bad English
