Volkswagen cars are created with many mechanical and electrical systems designed by some of the best auto technicians in the world. The top-notch engineering put into developing your Volkswagen and its fantastic performance on the road does not absolve it from the wrath of mechanical faults and natural wear and tear.
The fuel pressure regulator of your Volkswagen is an integral part that usually falls prey to natural wear and tear. The fuel pressure regulator is an essential part of the engine management system and the fuel control system. It is found in all internal combustion engines of Volkswagen models, and it controls the fuel flowing through the engine management system.
Most drivers of Volkswagen don’t know that different operating conditions of their car require an additional amount of fuel, which is measured by a change in fuel pressure. The fuel pressure regulator of some Volkswagen models uses vacuum diaphragms to change the fuel pressure effectively, while others use electronic fuel pressure regulators.
The fuel pressure regulator plays an essential role in the supply of fuel to the engine. Hence, when the fuel pressure regulator stops working, the engine might stop as well, since it is not getting sufficient fuel.
Symptoms of a Faulty Fuel Pressure Regulator
When the fuel pressure regulator of your Volkswagen stops working, you’ll notice some signs. These will determine if the fuel pressure regulator needs replacement or a simple fix. Whatever the case, a certified Volkswagen expert needs to diagnose it properly to inform you of the problem. Below are the signs to look for when the fuel pressure regulator stops working:
- Illumination of the Engine Warning Light: The check engine light located on the dashboard of your Volkswagen comes on only when the engine or its systems develops a fault. A defective fuel pressure regulator might also cause the check engine light to come on. Hence, a mechanic must inspect it to confirm that a faulty fuel pressure regulator is responsible.
- Reduced Engine Performance: The fuel pressure regulator is an integral part of the engine, and any slight fault with it will significantly impact the engine performance. When your engine makes a grinding noise or stalls upon starting your car, you will notice this. Also, when your vehicle is in motion, driving uphill will become difficult because your car will constantly jerk.
- Car Refuses to Start: When the engine of your Volkswagen can no longer handle the inadequacies of the faulty fuel pressure regulator, it will stop working. Contact your mechanic immediately to tow your car to the shop to help you resolve the issue.
- Heavy Smoke From the Exhaust Pipe: If you are an observant Volkswagen user, you’ll notice that the color of smoke from the exhaust pipe is usually clear. However, if the smoke suddenly becomes black, that indicates that something is amiss with your Volkswagen’s fuel pressure regulator. A damaged fuel pressure regulator will cause the engine in your Volkswagen to run on more fuel than usual; hence, the black smoke.
Other faulty parts in the engine compartment of your car can cause the exhaust pipe in your Volkswagen to give off black smoke. So it is not advisable to conclude that a faulty fuel pressure regulator is responsible. Always ensure that a mechanic carries out a thorough inspection of your car before coming to that conclusion.
