What Are The Signs Of Volkswagen Bad VVT Solenoid in Tolleson?

The most advanced innovation by automotive manufacturers is the variable valve timing that is used electronic technology for applying the variable electronic signals from the ignition system through a variable valve timing solenoid. Now it is virtually found in all production vehicles like Volkswagen throughout the states.

Every vehicle has its own unique VVT system that is relying on the fully functional variable valve timing solenoid for controlling the flow of oil to the VVT system. When you are putting a significant load against the engine, then the VVT system activates. The activated VVT solenoid will lubricate the variable valve timing chain and gear assembly through the oil.

If the VVT solenoid is failed, then the timing chain and gear are worn out prematurely due to the lack of proper lubrication. When the VVT solenoid is wearing out, there are several other problems found in Volkswagen.

Causes behind VVT solenoid problems

In general, the VVT solenoid is defined as an electrically powered system which is getting signal by the ECU. A small problem in the VVT system can fail the VVT solenoid of Volkswagen. The following points define the causes behind VVT solenoid problems in the vehicle:

• Internal electrical malfunction
• Internal mechanical failure
• Operate intermittently
• Lack of engine oil changes
• Outside contaminates
• Neglecting the filter changes
• Sticky deposits in the valve
• Blocked inline oil screen of valve oil inlet

Signs of bad VVT solenoid

When the VVT solenoid of the Volkswagen is failed due to any of the above-defined reasons, you will notice the following signs:

Contaminated engine oil

For the smooth functioning of the VVT solenoid, it needs clean or free of debris engine oil. But, when the engine oil is clogged due to the outside dirt or other foreign particles, then it will ultimately clog the passageway from the solenoid to the VVT chain and gear.

On the other hand, the low oil level will not only cause problems in the VVT solenoid but also damage several timing chain components. Avoiding the engine oil changes on a specified schedule could damage several parts such as:

• VVT solenoid
• VVT chain
• Gear drive

So, to protect the VVT solenoid from damages, change the engine oil as per the manufacturer's recommendation.

Reduce fuel mileage

The main purpose of the variable valve timing in the Volkswagen is to open and close the valves at the right time for maximizing the engine performance and reduce the fuel mileage ultimately.

When the VVT solenoid is damaged, then the functions of the entire system can be compromised and open and close the intake and exhaust valves at the wrong time. As a result, the fuel mileage of the vehicle can be reduced.

Activated check engine light

Now all the components of the Volkswagen are controlled by the engine control unit. When any of the components begin to fail, the ECU will store an error code for the problem that can be determined by using a scan tool. Once you will generate the error code of the problem, it will trigger the check engine light automatically.

Generally, there are dozens of codes are indicating the VVT solenoid problems in the vehicle. Due to these reasons, contact a certified mechanic for determining the error or download the code through the diagnostic tool. In this way, you can easily resolve the specific issues of Volkswagen.

Rough engine idle

When the engine has higher RPM and bears heavy loads while driving uphill will activate the VVT system of the vehicle. Due to any reason, if the VVT solenoid is damaged, then it will attract additional engine oil to the VVT gears and cause rough idling of the engine.

Neglecting the issues for longer can wear out additional engine components of the vehicle that need an immediate inspection by a certified mechanic.

Conclusion

For driving the vehicle safely on the road, you have to take proper care of the variable valve timing solenoid. If you are living in Tolleson and found any of the above-defined signs in your Volkswagen due to the bad variable valve timing solenoid, then contact a certified mechanic to inspect the vehicle and replace the variable valve timing solenoid to keep the vehicle running safely.
