Check Engine Vibrations/Oscillations

Model: Mercedes Classe E W124 - Years 1984-1995
Part: Checks and maintenance

The video shows a very original way to check for any abnormal engine vibrations. To clarify, if there is a combustion issue related to timing problems or dirt in the fuel filter or injectors, the engine will oscillate irregularly, causing noticeable jolts. However, a very simple way to perform this check is to place a bottle filled with water on the engine cover while the engine is running: if everything is normal, the bottle will sway slightly but remain in place.
