Does Enabling Hidden Features Affect the Volkswagen Sagitar?

Enabling hidden features can have significant impacts on a car. Here are the relevant details: The drawbacks of enabling hidden features: First, if a car has its hidden features enabled (specifically referring to the ECU), it is likely to lose the warranty service from the 4S dealership even during the warranty period. Second, if the ECU is modified to enhance performance, it will not only increase fuel consumption but also reduce the engine's lifespan and accelerate the aging of the vehicle's components. Naturally, this will also decrease the car's resale value. ECU Program: The so-called "ECU program" is essentially a set of algorithms stored in memory. It processes signals converted by the controller from input devices, generates corresponding command signals, and transmits them through output devices. Therefore, modifying ECU parameters is essentially altering these algorithms.
