What are the Signs of a Variable Valve Timing Unit Failure in a Volvo?
We all love a car that functions at optimum capacity. A properly-working Volvo delivers a satisfying driving experience almost every time. However, there are moments when your vehicle may begin to malfunction, thereby preventing you from enjoying the smooth ride you expect.
Although Volvos are revered for their high performance, even the best-made vehicles can start to develop problems. One of the common problems with Volvo is the variable valve timing unit failure.
The variable valve timing unit is a row of parts within the engine that gets activated to support the car when extra strain is put on it. The system uses various electronic signals from the ignition system via a variable valve timing solenoid. When required, producing this extra power prevents your engine from wearing out early due to excess strain.
The challenge for many drivers is knowing if the variable valve timing is working correctly. You would have to be very observant and vigilant to know when your car needs a service for valve timing failure because your Volvo’s variable valve timing system is a complex unit that requires the right expertise to diagnose and fix it.
Signs of a Variable Valve Timing Unit Failure In Volvo
There are sure signs your Volvo may manifest once it begins to experience a valve timing unit failure. At this stage, you would need to seek help by bringing your car to our certified mechanics, who will run diagnostics and detect the particular failure.
- Sudden sound change when idling: This is one of the significant signs of a failing variable valve timing unit. Many drivers ignore this until it becomes a bigger problem. The valve system is activated at higher rotations per minute, making it easy to hear a sound change when the car is idling. A sudden sound change when your Volvo is idling should alert you to a possible failure of the valve timing unit of your vehicle.
- Bumpy engine idle: A functioning ignition timing ensures that your engine runs smoothly without any hitches. The variable valve timing unit is built to monitor the engine and transmit information to the computer to adjust the valve timing once the car is under any strain. When the variable valve timing unit fails, its ability to transmit the correct information is hampered. The implication of this is that your car engine would experience a bumpy idle.
- Check engine light coming on: The check engine warning is an indication of an issue with the engine and should be treated with expediency. A failing variable valve timing unit is one of such components that could trigger the check engine warning. The variable valve timing unit gets monitored by your vehicle onboard computer. The computer gets alerted once there is a variable valve timing failure and activates the check engine light on the dashboard. You should seek help as quickly as possible whenever your check engine light comes up. Ensure you work with a certified technician for proper diagnostics and quality service.
- Reduced fuel efficiency: One typical sign of valve timing failure in your Volvo is a sudden decrease in fuel economy. Although there might be other reasons for this, it is one of the early signs to show that all is certainly not well with your vehicle’s engine.
- Dirty engine oil: If you notice your engine oil is always dirty, it could signify a variable valve timing unit failure. Dirty engine oil adds an extra strain to your car engine and could cause potential damage to it.
