The specific reasons for the Passat shaking when cold are: 1. Severe engine carbon deposits, dirty throttle or excessive carbon in the fuel injectors, requiring cleaning of the fuel system and checking whether the idle speed motor has carbon deposits that should be cleaned; 2. Ignition system issues, checking whether the spark plugs have excessive carbon deposits and replacing them if necessary; 3. Unstable fuel pressure, requiring inspection at a 4S shop to check the fuel supply pressure and whether the intake pressure sensor is normal, with parts replacement if necessary. The Passat is a mid-size sedan designed by Volkswagen AG of Germany, classified as a B-segment car in the Volkswagen lineup. In terms of body dimensions, the Passat measures 4870mm in length, 1834mm in width, and 1472mm in height.
