Where to Address Volvo Variable Valve Timing Unit Issues in Austin

Are you aware that the VVT system in your Volvo helps to control the timing of your engine’s intake and exhaust valves depending on the driving conditions? Yes, it enables the engine to offer better fuel economy at low speeds while offering more power at high speeds. In Volvos, the VVT unit is operated by oil pressure and uses solenoids to change the position of the camshaft. When everything is fine, you will have a smooth acceleration and the fuel efficiency will be better and the emission level will be low. However, when the VVT unit is not functioning properly, it affects the timing of the engine and the performance difference can be easily noticed.

Volvo VVT Unit Failure Causes

Lack of Proper Oil Maintenance: The VVT system requires engine oil to operate and when this fluid is not properly maintained, it will lead to the deterioration of the system. Contaminated or low oil creates sludge which hinders the smooth working of the VVT solenoid making it impossible for it to change the camshaft timing appropriately. Proper oil changes with the right synthetic oil will be beneficial to the smooth running of the system.
Worn VVT Gears or Solenoids: The VVT gear and solenoid assemblies are subject to wear and tear because of their frequent use. When these components become worn out, they can lead to improper timing of the valves and affect the performance of the engine as well as produce abnormal noises.

How To Address Volvo VVT Issues

Diagnosing the Problem: A certified Volvo technician will begin by connecting a scan tool to the engine control module (ECM) to retrieve codes that are associated with the VVT system. They will also check on the quality of oil, solenoids, and VVT gears to identify the root cause of the problem.
Replacing the VVT Gear: In the event that the VVT gear is worn out, it will have to be replaced. This repair process entails the removal of the timing belt or timing chain, replacement of the defective gear, and then putting the engine back together with the right timing.
Cleaning or Replacing VVT Solenoid: If the problem is related to the solenoid, then the mechanic will clean or replace it. A solenoid may sometimes be cleaned using solvent but if it is really bad, it will require replacement.
Changing the Oil and Cleaning the System: If there is a problem with the VVT system due to the build-up of sludge, the oil may need to be changed and the engine may need to be flushed. High-quality synthetic oil, specifically created for Volvos, can help avoid future VVT problems.

Preventing Future VVT Problems

Regular Oil Changes: Getting an oil change every 5,000 to 7,500 miles is one of the ways to ensure that the VVT system is not compromised because it works with the help of clean oil. You should always use the right type of oil recommended by Volvo to avoid an accumulation of sludge.
Routine Maintenance: A trained technician can always check for minor VVT problems during a routine inspection of your Volvo. In this case, it is advisable to check for oil leaks, worn gears, or clogged solenoids to avoid costly repairs in the future.
Utilizing High Quality Parts: If your Volvo requires a VVT repair, always use either OEM or high-quality third party parts to avoid disappointments in the near future. Using cheap and substandard parts will result in frequent breakdowns and additional problems.
