High quality electromagnetic coil 06R109165B for imported Audi Q5.

High-Quality Electromagnetic Solenoid Valve 06R109165B for Imported Audi Q5 – Full Product Introduction
 
1. Basic Product Information
 
1. OE Part Number: 06R109165B
2. Official Name: Camshaft Adjuster Solenoid Valve (commonly known as VVT timing solenoid valve in the industry, integrated assembly of electromagnetic winding, valve body and sealing base)
3. Applicable Vehicle: Imported Audi Q5 equipped with EA888 06R-series 2.0T engine; interchangeable with Volkswagen, Skoda and SEAT models with the same 06R engine platform
4. Product Positioning: Core electronically controlled actuator of engine valve train system. The term "electromagnetic coil" is a common commercial name; the unit integrates electromagnetic winding, valve body and sealing base as one assembly.
 
2. Core Working Principle
 
1. The vehicle ECU sends 12V pulse electrical signals to the coil winding to generate controllable electromagnetic force upon energization.
2. The electromagnetic force pushes the internal valve spool to switch engine oil passages and adjust the oil pressure of the camshaft adjuster.
3. It dynamically alters the phase of intake and exhaust camshafts and adjusts the opening/closing timing of valves in real time.
4. After power cut-off, the built-in spring resets the spool, the oil passage returns to the initial state, and the cam phase resets.
 
3. Premium Materials & Manufacturing Advantages
 
(1) Core Coil Winding
 
- Adopts high-purity oxygen-free copper enameled wire with tightly multi-layered winding strictly following original factory specifications.
- High-temperature resistant insulating varnish withstands ambient temperatures from -40°C to 150°C inside the engine bay, preventing short circuits and coil burnout.
- Vacuum impregnation sealing process isolates engine oil and moisture to avoid inter-turn electric leakage.
 
(2) Valve Body & Outer Housing
 
- Base made of glass fiber reinforced PA66 high-temperature engineering plastic, resistant to engine oil corrosion and deformation cracking.
- Precision cold-forged steel spool with mirror-polished surface ensures smooth oil pressure regulation without jamming.
- Integrated fluororubber sealing gasket delivers long-term oil leakage prevention and eliminates oil seepage on timing covers.
 
(3) Electrical Connector
 
- Factory-standard 2-pin waterproof plug with dustproof lock to prevent water ingress and fault codes in rainy weather or after car washing.
- Thick gold-plated conductive terminals resist oxidation and enable stable, delay-free signal transmission.
 
4. Key Functions
 
1. Boost Power Output: Advances intake valve opening at high RPM to increase air intake, reduce turbo lag and deliver snappier acceleration.
2. Cut Fuel Consumption: Delays valve closing at low RPM to minimize pumping loss and improve fuel economy during city commuting.
3. Smooth Idle Operation: Precisely controls valve overlap angle to reduce idle vibration and enable stable cold starts.
4. Lower Exhaust Emissions: Optimizes full combustion to reduce carbon monoxide and hydrocarbon pollutants, avoiding failed emission inspections.
 
5. Typical Fault Symptoms of Damaged Units
 
Aged, short-circuited or seized coils lead to the following issues:
 
1. Illuminated engine malfunction indicator lamp with fault codes P0011/P0012/P0016 (camshaft timing deviation) read via diagnostic scanner.
2. Difficult cold cranking, delayed startup and obvious rough idle when the engine warms up.
3. Sluggish acceleration, dull throttle response and weak overtaking power.
4. Engine oil seepage from the coil base resulting in oily timing cover surfaces.
5. Unusual rise in fuel consumption and abnormal engine ticking noises (timing chain rattle).
 
6. Technical Specifications
 
- Rated Operating Voltage: 12V DC vehicle power supply
- Control Mode: ECU PWM pulse modulation
- Coil Response Time: ≤0.5 seconds
- Maximum Withstand Oil Temperature: 150°C
- Installation: Bolt-mounted on timing end cover, single unit per cylinder bank
- Direct Replacement: 1:1 replacement for OEM 06R109165B, plug-and-play with no modification required
 
7. Advantages of Premium Units vs. Low-Cost Generic Alternatives
 
1. Matches original factory coil resistance to avoid false ECU fault codes; cheap generic parts feature inconsistent resistance that triggers warning lights immediately after installation.
2. High-temperature sealed construction prevents oil leakage under long-term high heat; budget alternatives tend to seep oil within 3–6 months.
3. Uniform and stable electromagnetic force delivers accurate cam phase adjustment without acceleration jerking.
4. Service life matches OEM standards, supporting 80,000–120,000 km normal driving, while generic counterparts fail prematurely after 20,000–40,000 km.
5. 100% factory testing for electrical conduction and oil tightness, resulting in extremely low post-installation failure rates.
 
8. Installation & Replacement Guidelines
 
1. It is recommended to replace intake and exhaust solenoids in pairs to eliminate inconsistent performance between old and new components.
2. Clean accumulated oil on the timing cover during disassembly and install a matching new sealing gasket.
3. Clear fault codes with a diagnostic scanner after replacement and conduct road testing to recalibrate camshaft timing.
4. Recommended maintenance scenarios: engine overhaul, timing chain kit replacement, and troubleshooting for fault code P0011.
 
9. Compatible Extended Models with 06R Engine
 
Imported Audi Q5, Audi A4, A5, Imported A6; Volkswagen Tiguan, CC, Golf R and other vehicles fitted with EA888 Gen 2 06R 2.0T engines.
