How often should the throttle valve of an Audi Q5 be cleaned?

Audi Q5's throttle valve should be cleaned approximately every 20,000 to 40,000 kilometers. The throttle valve is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. The Audi Q5 has a body size of: length 4753mm, width 1893mm, height 1659mm, with a wheelbase of 2908mm and a fuel tank capacity of 73 liters. The Audi Q5 is equipped with a 2.0L turbocharged engine, delivering a maximum power of 169 kilowatts and a maximum torque of 350 Newton-meters, paired with an 8-speed automatic transmission.
When I used the Audi Q5 before, I found that the timing for throttle valve cleaning was quite flexible. My car usually needed it every 20,000 to 30,000 kilometers, depending on the daily driving conditions. For example, frequent stop-and-go traffic in the city leads to faster carbon buildup, which can easily cause unstable idling or increased fuel consumption. Once, I waited until 35,000 kilometers to clean it, and the car shook badly at startup, but after cleaning, it ran noticeably smoother. The cleaning cost at a professional shop is around 200-300 RMB, which isn’t expensive. The key is to check regularly and not wait until major issues arise, especially since delayed acceleration at high speeds can increase safety risks. According to the maintenance manual, Audi recommends periodic treatment based on conditions. From my experience, a preventive cleaning every two years or 30,000 kilometers is quite reasonable.
