What causes engine vibration in Volkswagen Santana Vista?
1 Answers
The cause of engine vibration in Volkswagen Santana Vista is severe carbon buildup. Ignition system issues: Check the working condition of spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or improper spark plug firing can also lead to such fault symptoms. Solution: Check if spark plugs have excessive carbon buildup and replace them if necessary. Unstable fuel pressure: If you have already cleaned engine carbon deposits, washed the throttle body, replaced gaskets and spark plugs, but still notice body vibration at idle, it is recommended to visit a 4S shop to check fuel supply pressure and the intake pressure sensor for proper functioning. Abnormal fuel pump supply pressure or incorrect readings/malfunction of the intake pressure sensor can generally cause body vibration. Solution: Check fuel pressure and replace components if necessary. Aging engine components: Car vibration may also be related to aging engine mounts (also known as engine cushions). Engine mounts serve as the vibration damping system for the engine, absorbing minor vibrations during operation. If engine mounts develop problems, these vibrations will be transmitted to the steering wheel and cabin, causing vibration at idle. Solution: Replace the components.
