What is the cause of abnormal noise when releasing the accelerator in a Skoda Octavia?

Skoda Octavia's abnormal noise when releasing the accelerator is caused by the engine timing chain. Common faults causing abnormal noise when releasing the accelerator: It may be due to issues with the valve train, or engine carbon buildup. These conditions can cause abnormal noise when the vehicle is driven normally and the accelerator is released. Among them, problems with the valve train are the most common cause of abnormal noise after releasing the accelerator, such as issues with the chain, valves, etc. Wear on the camshaft profile is most likely to cause abnormal noise when releasing the accelerator. Other causes include excessive valve clearance, excessive clearance between the tappet and its guide hole, worn camshaft profile, excessive clearance between the valve stem and its guide, or a stuck valve that cannot close. The root of the abnormal noise when releasing the accelerator: Is it coming from the engine compartment or elsewhere? For example, in some rear-wheel-drive models, releasing the accelerator can also cause gear noise. However, regardless of the cause, it is best to have it inspected at a 4S shop or a professional auto repair shop.
I also experienced strange noises when releasing the throttle while driving my Skoda Octavia. It felt like something small was shaking, which gave me quite a scare. It's most likely caused by a loose engine belt or chain - when releasing the throttle, the slipping belt produces squeaking sounds. It could also be the clunking noise from transmission jerks, especially in DSG models. Regular maintenance is crucial when driving, such as checking the belt tensioner and transmission fluid levels. If ignored, the chain might wear out severely and damage the engine. I found that gently pressing the throttle a few times to locate the sound source before deciding to visit the repair shop can save unnecessary expenses.
