1. Basic Product Information
OE Part Number: 06R109259B
Official Name: Camshaft Adjuster Electromagnet (VVT Timing Magnet, integrated assembly of electromagnetic coil, valve spool and sealing base)
Applicable Vehicle: SAIC Volkswagen Teramont Pro equipped with EA888 06R-series 2.0T engine; interchangeable with other VAG models fitted with the same engine platform
Product Definition: Core electronic control actuator of engine variable valve timing system. The term "electromagnet" is the common commercial name for this integrated oil control solenoid assembly.

2. Core Working Principle
The vehicle ECU transmits 12V PWM pulse signals to the internal coil winding, generating controllable electromagnetic attraction when energized.
Electromagnetic force pushes the built-in metal spool to switch engine oil passages and adjust hydraulic pressure of the camshaft phaser.
It dynamically modifies intake and exhaust camshaft phases, adjusting valve opening and closing timing in real time to match different driving conditions.
After power cut-off, the built-in return spring resets the spool, oil passages revert to original state, and cam timing returns to default position.
3. Premium Raw Materials & Manufacturing Advantages
(1) Internal Electromagnetic Coil
Adopts high-purity oxygen-free copper enameled wire with multi-layer dense winding strictly following OEM resistance parameters.
High-temperature resistant insulating coating withstands engine bay operating temperature range of -40°C ~ 150°C, effectively preventing short circuit and coil burnout.
Full vacuum impregnation sealing process isolates engine oil, steam and dust to eliminate inter-turn leakage.
(2) Housing & Valve Spool
Reinforced PA66 glass fiber high-temperature plastic base, resistant to oil corrosion, cracking and thermal deformation under long-term high heat.
Precision cold-forged steel spool with mirror polishing surface, ensuring smooth oil pressure regulation without sticking or jamming.
Integral fluororubber sealing gasket delivers permanent anti-leak performance to stop oil seepage on cylinder head covers.
(3) Electrical Connector
Standard 2-pin waterproof plug with dustproof lock structure, preventing water ingress and fault codes during rainy days or car washing.
Thick gold-plated conductive terminals resist oxidation, realizing stable, delay-free signal transmission.
4. Main Functional Benefits
Boost Power Performance: Advances intake valve opening at high RPM to increase air intake, reduce turbo lag and deliver snappier acceleration for large SUVs like Teramont Pro.
Lower Fuel Consumption: Delays valve closing at low-speed cruising to reduce pumping loss and improve fuel economy during daily commuting.
Stabilize Idle Condition: Precisely controls valve overlap angle to mitigate idle vibration and achieve smooth cold startup.
Reduce Exhaust Pollutants: Optimizes fuel full combustion to cut CO and hydrocarbon emissions and avoid failed vehicle emission inspections.
5. Typical Fault Symptoms of Damaged Electromagnet
Aged, short-circuited or seized electromagnets trigger the following malfunctions:
Engine malfunction indicator lamp illuminates, with diagnostic trouble codes P0011/P0012/P0016 (camshaft timing deviation) detected via scanner.
Difficult cold cranking, delayed ignition and obvious rough idle after engine warm-up.
Sluggish throttle response, weak acceleration and insufficient overtaking power.
Engine oil seepage from the electromagnet mounting base, causing oily residue on cylinder head.
Abnormal fuel consumption rise and abnormal timing chain rattling noise from the engine.
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 Method: Bolt-mounted on cylinder head, single unit per camshaft
Replacement Feature: Direct 1:1 replacement for OEM 06R109259B, plug-and-play without modification
7. Advantages of High-Grade Electromagnet vs. Low-Cost Generic Parts
Matches OEM coil resistance to avoid false ECU fault codes; cheap generic products have inconsistent resistance and trigger warning lights immediately after installation.
High-temperature sealed structure prevents oil leakage under long working heat; budget alternatives tend to leak oil within 3–6 months.
Uniform and stable electromagnetic force ensures accurate cam phase adjustment without acceleration jerking.
Service life consistent with OEM standard, supporting 80,000–120,000 km normal driving, while low-cost copies fail prematurely after 20,000–40,000 km.
100% factory dual inspection for electrical conduction and oil tightness, resulting in ultra-low post-installation failure rate.
8. Installation & Replacement Guidelines
It is recommended to replace intake and exhaust side electromagnets in pairs to eliminate inconsistent performance between old and new components.
Clean accumulated sludge and oil on the cylinder head during disassembly, and install a brand-new matching sealing gasket.
Clear fault codes with professional diagnostic equipment after replacement, then conduct road test to recalibrate camshaft timing.
Applicable maintenance scenarios: engine overhaul, timing chain kit replacement, troubleshooting for fault code P0011.
9. Compatible Extended Models with 06R EA888 Engine
SAIC Volkswagen Teramont Pro, Teramont, Tiguan L, Passat, Arteon; Audi A4L, A6L, Q5L and other domestic VAG vehicles equipped with EA888 06R 2.0T engines.
