What does EST mean on a Volkswagen car?
1 Answers
The EST icon on the car dashboard indicates a problem with the vehicle's stability control system. Automotive Electronic Devices: The vehicle's electronic stability control system is an automotive electronic device that further enhances the anti-lock braking and traction control functions. The stability control system helps maintain the vehicle's stability during driving and better handles various complex road conditions, ensuring driving safety. Functions of the Vehicle Stability Control System: The electronic stability control system includes electronic brake-force distribution and anti-lock braking systems. It adjusts braking force distribution to prevent the rear wheels from locking up first, and typically only fails when there is a hardware malfunction in the module. It prevents wheel lock-up by calculating the vehicle's slip rate and controlling it near the peak adhesion coefficient, which is part of passive safety control.
