What does it mean when the Audi brake servo system function is restricted?

Brake servo system function restriction indicates that you need to go to the nearest 4S store for repair, and it is not recommended to continue driving. The following is relevant information about Audi: 1. Introduction: Audi is a famous car developer and manufacturer. It is now a subsidiary of Volkswagen AG in Germany, with its headquarters in Ingolstadt, Germany. The main models include Audi A1, Audi A3, Audi A4, Audi A5, Audi A6, Audi A7, Audi A8, Audi Q1, Audi Q2, Audi Q3, Audi Q5, Audi Q7, Audi Q8, Audi TT, Audi R8, and the S and RS performance series. 2. Logo: Since 1932, Audi has adopted the four-ring emblem, which symbolizes the merger of Audi with DKW, Horch, and Wanderer to form the Auto Union company.
Last time I drove my Audi Q5 to the supermarket, I noticed the brake pedal felt unusually hard when stopping at a red light, and the dashboard displayed a warning saying 'Brake Servo System Function Limited.' This means the brake assist was failing, requiring much more effort to stop the car, which was quite dangerous. My engineer friend explained that this system relies on vacuum or electric assistance to reduce pedal pressure, and such malfunctions often occur due to vacuum pump leaks or faulty electronic control modules—common issues in Audis. The mechanic warned me to pull over immediately and check for cracks in the vacuum lines, as continuing to drive could easily lead to a rear-end collision. Regular maintenance, like cleaning dust buildup, helps prevent such failures—safety should never be taken lightly. That incident left me sweating bullets, but timely repairs fixed it. Never ignore small warning signs, folks.
