In 2007, I was trapped in Passat, and there was a little air leakage. Can I still drive?

Still open. If you run a long distance, you'd better solve it before running. Mainly check the intake manifold from the throttle to the engine, including the vacuum tube of the brake booster. There is a pipe under the air cabin, which is probably not plugged in properly. The problem of air leakage in the air intake system must be inspected by professionals on the spot to know where the specific problem lies. The following is an introduction to the working principle of the air intake system: 1. When the engine is working, the driver controls the opening of the throttle through the accelerator pedal to change the air intake and control the operation of the engine. 2. After the air entering the engine is filtered by the air cleaner to remove impurities such as dust, it flows through the air flow meter, enters the power room along the throttle passage, and then is distributed to each cylinder through the intake manifold. 3. When the engine is idling, part of the air bypasses the throttle valve and enters the cylinder through the additional air valve or idling control valve.
