5 Reasons Why Your Volkswagen Engine is Making Loud Noise from Experts in Yardley

Among the various automobile manufacturers around the world, there are few who stand out because of their consistent endeavor to provide their customers with something new every time they buy a car of their brand. One such highly popular global automotive brand is Volkswagen.

Volkswagen is known for its reliability and performance and it comes equipped with many advanced features that help in the smooth running and better performance of the car. However, these advanced features don’t make your Volkswagen immune to issues.

Like every other car, Volkswagen has also got certain inherent problems that can be resolved if you are having a better understanding of the problem. One such issue reported by most Volkswagen drivers is hearing a loud noise from the engine of their car.

Hearing loud noises from the engine of your Volkswagen signifies issues that need to be diagnosed immediately and corrective measures taken in order to prevent further damages to the engine. Here are the 5 reasons behind your Volkswagen engine making a loud noise.

Damaged knock sensor

If you are hearing a metallic knocking or pinging sound when you are driving your Volkswagen, then it is likely a detonation knock. It means that the air and fuel mixture in one or more of your engine’s cylinders is detonating in more than one place simultaneously.

Moreover, this knocking sound can also be caused due to a combination of gas with the wrong octane rating in your engine. In addition to this, the sound you hear can also be caused due to poor timing in your Volkswagen’s engine, a lean air to fuel mixture, or the knock sensor might have been damaged.

Engine backfires

At times you might get to hear a loud explosion from your Volkswagen that might seem like a firework. Whenever you hear such a sound, you can be certain that this sound is caused due to an engine backfire from your Volkswagen. Engine backfiring issue is caused when the fuel that has not been burned in the combustion chamber escapes & combusts in the exhaust.

Furthermore, a fuel-to-air ratio that is either too lean or too rich can cause a backfire. The backfiring issue needs to be addressed immediately as it can lead to serious engine damages and ultimately your Volkswagen might need a costly engine rebuild.

Low engine oil

If you are hearing a grinding or loud rubbing noise from under the hood of your Volkswagen, then make sure to inspect the engine oil levels of your car. If you are having a new Volkswagen then it comes equipped with an engine oil level monitor, however, older versions of VW might not have this feature.

It is a better idea to have a look at the engine oil levels when you get to hear grinding sounds from your car. The engine requires oil for lubrication and smooth functioning. If the oil levels in your VW are not adequate, then it can cause significant damage to the engine.

Damaged muffler

At times the loud noise you hear from the engine might not be due to the engine having a problem at all. Instead, this sound might be caused due to a failing muffler. If you notice that your VW is running louder than usual and there aren’t any other unusual sounds, then it is a damaged muffler.

In addition to this, if you observe more fumes coming out from your car or your gas mileage has been affected considerably, then you can be sure that the problem lies with the damaged muffler. This problem might not require an immediate fix but you should contact a technician as soon as possible.

Worn torque converter

Nowadays, as all the cars are coming equipped with an automatic transmission your Volkswagen is not an exemption. Along with the automatic transmission your VW has also got a torque converter for the smooth functioning of the transmission system.

If the transmission fluid in your VW is too low, then the torque converter can start to fail. This causes grinding noise when the car is in gear. The damage or wear to the needle bearing is causing this sound.

Finally

The above-discussed factors often lead to loud noises from the engine of your Volkswagen. Most of the time it is seen that Volkswagen owners don’t take these sounds seriously and end up causing more damage to the engine. Whenever you hear any abnormal sound from your car and then take it to the nearest local mechanic for diagnosing & addressing the problem.
