Why is the engine sound of the Tharu so loud?

The loud engine sound of the Tharu may be due to poor sound insulation, insufficient antifreeze, or the engine not adapting to the viscosity of the engine oil. Below are detailed explanations of the reasons for the loud engine sound in the Tharu and their solutions: Engine not adapting to the viscosity of the engine oil: After prolonged driving, the engine oil becomes thinner, and carbon deposits accumulate. When new engine oil is replaced, the engine may not adapt to its viscosity, potentially increasing the RPM, which in turn causes the engine noise to become louder. Solution: Replace the engine oil or wait for the noise to decrease over time with usage. Poor sound insulation: The loud sound may be caused by the engine's own poor sound insulation. Solution: Inspect the car's sealing strips. If the sealing strips have aged, they need to be replaced with new ones. Insufficient antifreeze: In low-temperature conditions, antifreeze is prone to being insufficient, which can lead to increased engine noise. Solution: Add more antifreeze.

The loud engine sound of the Tharu has inherent factors. The EA211 engine it uses aggressively extracts horsepower at high RPMs, and exceeding 3000 RPM feels like activating sport mode. My car, with over 30,000 kilometers, has experienced three types of abnormal noises being resolved: a whistling sound discovered after the first maintenance was due to a loose turbo intake pipe clamp; a clunking noise when going over speed bumps in the second year was fixed by replacing the left front engine mount rubber pad; and a recent squeaking sound during acceleration was addressed by replacing the aging alternator belt. A common issue with Volkswagen cars is the abundance of plastic parts, leading to friction noises from various conduit brackets in the engine bay over time. It's recommended for new owners to keep a video of the first cold start for future comparison. Actually, placing a coin upright on the steering wheel to test vibrations when parked is more accurate.
