What causes the beeping sound in the Volkswagen Lavida engine?

[VanAiden]

The reasons for the beeping sound in the Volkswagen Lavida engine are as follows: 1. Piston material issue: The engine oil is incompatible with the piston material, causing wear and requiring replacement with improved pistons; 2. Engine oil quality: Improper use or failure to replace expired oil can affect the normal operation of the engine. The correct oil type must be selected, as different friction coefficients also impact engine performance; 3. Aging or loosening of fasteners: Worn engine mount bushings can cause shaking and abnormal noises at high speeds; 4. Abnormal noises from the valve train: Issues such as excessive valve clearance, excessive clearance between the tappet and its guide hole, radial cracking of the camshaft timing gear, or loose valve seat rings can all lead to abnormal engine noises.
