Is your Volkswagen hard to start or stalling while driving? It may be time to consider changing the ignition coils. Ignition coils are one of the most important components in the engine of your VW. They transform the low voltage produced by the battery into high voltage that is required to light up the spark plugs that ignite the fuel in the engine. In most of the current Volkswagen models, there is one ignition coil per cylinder, while in the previous models, there is only one ignition coil, which distributes the voltage to the various cylinders through a distributor. Regardless of the amount of ignition coils contained in your vehicle, if any ignition coil fails, the cylinder will not get the required spark and this will cause different problems that will affect the performance of the engine. How You Can Spot Ignition Coil Failure ... read more

How To Deal With Your Volkswagen's Mass Airflow Sensor Failure   The MAF or Mass airflow sensor in your Volkswagen is a very important component needed for the proper operation of your car’s engine. The MAF sensor quantifies the flow rate and air density of the air that is drawn into the engine. This information is taken to the engine control unit, or ECU as it is commonly referred to, and the fuel injection is modified to suit the combustion process. However, a bad MAF sensor can interfere with this balance and cause a number of issues with the engine. Here are some steps that will help you handle Volkswagen MAF failure. How Sensor Failure is DiagnosedVisual Inspection The MAF sensor is commonly placed somewhere between the air filter and the ... read more

Familiar Signs of an O2 Sensor Failure in Your Volkswagen Volkswagens are recognized for their distinguishable designs and safety. They provide drivers with a smooth and comfortable ride. VW's are highly dependable but do see some common component failures such as O2 sensor failure. The O2 sensor is also known as the oxygen sensor. It is a critical component of the exhaust system. Its function is to measure oxygen levels. This helps the computer determine the proper air to fuel ratio. Without the correct ratio, the performance of your Volkswagen will be greatly impacted. If the O2 sensor fails, the combustion process in the engine will be affected. This can lead to high emissions, and damage to the engine and catalytic converter. Symptoms of O2 Sensor Failure in Your Volkswagen ... read more

Some Volkswagen vehicles experience a manufacturing error when it comes to the rear springs. This may not affect every Volkswagen owner, but it is essential to know a potential mechanical pitfall that could lead to a dangerous or scary experience while driving down the road.   The rear coil springs are a part of your Volkswagen’s suspension system. As you drive on the road, whether it is a smooth surface or bumpy and rough, the suspension system absorbs the shock of the impact.   A sound suspension system keeps your drive a smooth experience if you commute on relatively non-challenging terrain. However, if you do end up running over a particularly sizable pothole, speedbumps, or debris, the suspension system comforts the impact so it's not too jarring. However, a large amount of wear and tear on the rear coil springs in your Volkswagen increase ... read more
