What is the reason for the Volkswagen Sagitar engine making dry noise without power when stepping on the accelerator?

Reasons for the Volkswagen Sagitar engine making dry noise without power when stepping on the accelerator: Excessive engine carbon deposits: Excessive carbon deposits on the throttle valve, excessive carbon deposits on the spark plugs, etc. Regularly remove carbon deposits from the car and clean them; Dirty air filter causing poor filtration: Go to a repair shop for cleaning or replacement; Insufficient gasoline grade: Use high-quality engine oil and switch to higher-grade gasoline; Spark plug aging, car idling issues: Spark plugs are important components of the gasoline engine ignition system. They introduce high voltage into the combustion chamber and generate sparks by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. Go to a repair shop for maintenance.
I've been driving a Volkswagen Sagitar for over a decade and have genuinely encountered this issue of the engine revving without delivering power when stepping on the gas. The most common cause is clutch slippage—for manual transmissions, worn clutch plates fail to transfer power, much like pedaling an empty bicycle; for automatics, it could be a problem with the torque converter, where insufficient lubrication leads to idle spinning. Another culprit is a clogged air filter, starving the engine of air and sapping its strength, or aged spark plugs struggling to ignite, which also results in poor performance. I remember one time after a car wash, poor sealing let dust in, and the filter got so dirty that replacing it fixed the issue. I recommend routine maintenance checks on these components. If the problem arises, pull over immediately instead of forcing it, to avoid damaging more parts—a friend of mine once towed his car in for repairs and spent a lot of unnecessary money. Prevention is better than cure; replacing filters and small parts isn’t costly but is crucial.
This symptom is commonly seen in repair shops, especially with Volkswagen Jettas. Clutch slippage is the main cause - whether it's worn clutch discs in manual transmissions or low/ineffective torque converter fluid in automatics, power fails to reach the wheels. Fuel system issues shouldn't be ignored either; a clogged fuel pump or dirty injectors starving the engine will make it whir weakly without power. Additionally, aging ignition coils or spark plugs causing incomplete combustion also affect output. Pay attention to unusual smells or noises while driving - a burning clutch odor is a warning sign. It's best to stop and check simple components like air filters and spark plugs. Address issues promptly at professional shops to avoid major transmission overhauls, which are both costly and dangerous. Early intervention brings peace of mind.
My Volkswagen Sagitar had a similar issue last year, where it would make noise but not move when I stepped on the gas—really nerve-wracking. Most of the time, it's an ignition system problem, with spark plugs or coils failing to ignite properly, or insufficient fuel or air restricting power. A quick check of the air filter to see if it's clogged—take it out and inspect for dirt—can help. Sometimes, cleaning the throttle body also works. My friend's car ran fine after replacing the spark plugs, but I don’t recommend DIY fixes. It’s better to have a repair shop read the diagnostic codes for accuracy. Daily driving tips: warm up the engine before driving and accelerate gently to protect components. If you notice a fault, slow down, stop, and wait for assistance—don’t risk driving at high speeds to avoid further damage. Short-term issues are easier to fix; prolonged neglect causes more harm.
