EA839 3.0T/2.9TT & EA825 4.0TT Engine Variable Valve Timing (VVT) Oil Control Valve | Genuine Audi | B9 S4, S5, SQ5

Overview

The Genuine Volkswagen/Audi Engine Variable Valve Timing (VVT) Oil Control Valve is responsible for regulating oil flow to the camshaft adjusters, allowing the engine to continuously optimize valve timing for changing driving conditions. By precisely controlling camshaft position, the VVT system helps deliver responsive performance, smooth idle quality, improved fuel efficiency, and reduced emissions.

Over time, contamination, sludge buildup, or internal wear can reduce the valve's ability to regulate oil flow accurately, resulting in camshaft timing faults, rough engine operation, hesitation, or a Check Engine Light. Replacing a worn or malfunctioning oil control valve with a genuine OEM component helps restore proper VVT operation and ensures the engine performs as Volkswagen and Audi intended.

Details

• Genuine Volkswagen/Audi OEM Part
• Part Number: 06M109257AF
• Controls Variable Valve Timing – Regulates engine oil flow to the camshaft adjusters for precise valve timing control.
• Restores Engine Performance – Helps maintain smooth idle, consistent power delivery, fuel efficiency, and emissions compliance.
• Direct OEM Replacement – Engineered for factory fitment and seamless installation.
• Common Repair for VVT System Faults – Recommended when diagnosing camshaft timing-related trouble codes, poor idle quality, hesitation, or variable valve timing performance issues.
• Supersedes Previous Revisions – Replaces earlier part numbers 06M109257M, 06M109257Q, and 06M109257T.
• OEM Quality Construction – Built to withstand the high temperatures, oil pressure, and demanding operating conditions found in modern Volkswagen and Audi engines.
• Quantities: Four (4) VVT Oil Control Valves are required to replace all oil control valves during a complete timing service on EA825 4.0T engines (RS6, RS7, RS Q8, S8, SQ7, SQ8, etc.).

  Note: Proper engine oil quality and routine maintenance are essential for reliable VVT system operation. Before replacing the oil control valve, verify that the engine has the correct oil level and that no underlying lubrication issues are present.
