VVT Solenoid 06E109257L For Audi A4 A5 A6 Q5 S4 S5 — OEM Camshaft Control Valve
The Variable Valve Timing (VVT) Solenoid with OEM reference number 06E-109-257-L is a verified direct-fit replacement for a wide range of Audi vehicles equipped with 3.0L V6 (supercharged), 3.2L V6, and 4.2L V8 engines. This solenoid, also known as the N205 valve or camshaft adjustment control valve, is a critical component of the engine's variable valve timing system.
The VVT solenoid works by altering the supply of oil pressure to the camshaft and can either advance or retard the camshaft position to provide optimal performance. It controls the flow of oil to the VVT system, which adjusts the timing of the opening and closing of the engine's intake and exhaust valves. This adjustment allows for optimal engine performance, improved fuel efficiency, and reduced emissions by enabling the engine to operate more efficiently across different RPM ranges.
A faulty VVT solenoid can lead to a Check Engine Light, poor acceleration, rough idling, and reduced fuel economy. If the VVT solenoid fails or is blocked, the lack of proper lubriion can cause the timing chain and gear to prematurely wear. This OE-spec replacement solenoid restores proper valve timing, engine performance, and fuel efficiency.
Manufactured to meet or exceed original equipment standards, this solenoid features high-quality steel components to resist heat and pressure, premium O-rings and gaskets to prevent oil leaks, and improved steel components to limit sticking during oil sludge buildup. Each unit undergoes 100% quality control and end-of-line testing.
⚠️ Important: This solenoid has an extremely high failure rate. If your car is throwing a code for the N205 valve, you should replace this part to maintain engine health.

Installation & Maintenance Recommendations
⚠️ IMPORTANT: VVT solenoid replacement requires mechanical competence. Professional installation recommended.
When to Replace:
- Check Engine Light with N205 valve codes
- Poor acceleration, hesitation, or reduced power
- Rough idling or unstable RPM
- Decreased fuel economy
- As preventive maintenance on high-mileage vehicles
Installation Guidelines (Reference Audi workshop manual for complete steps):
- Safety first — allow engine to cool completely before starting work
- Disconnect battery negative terminal
- Loe the VVT solenoid on the engine (camshaft adjustment valve area)
- Disconnect the electrical connector
- Remove the solenoid mounting bolt(s)
- Carefully remove the old solenoid — note the position of O-rings and seals
- Compare the new solenoid with the old unit — verify part number (06E-109-257-L) matches
- Inspect the solenoid bore for debris or sludge — clean if necessary
- Install new O-rings and seals (included with the assembly)
- Install the new solenoid into position
- Torque mounting bolt(s) to manufacturer specifiion
- Reconnect the electrical connector
- Reconnect battery
- Clear fault codes with a diagnostic scan tool
- Start engine and verify proper operation — no Check Engine Light, smooth idle, responsive acceleration
Pro Tips:
- If the solenoid failed due to dirty engine oil or debris blockage, change the engine oil and filter
- Dirty engine oil can cause blockages in the solenoid — regular oil changes prevent premature failure
- Use only OEM or OEM-grade replacement parts for critical engine components
