High-quality Crankcase PCV Valve 03F 103 175 A for FAW Audi A1

Core Selling Points

Fast-selling engine consumable for bundled one-stop procurement

100% OE identical dimension, direct plug-in installation without modification

Applicable Vehicle & Engine Scope

• Main Fit Model: FAW Audi A1
• Matched Engines: 1.2 TSI, 1.4 TFSI turbocharged gasoline engines
• Interchangeable Compatible Models: Audi A3, VW Polo, Golf 6/7, Ibiza, Toledo and other VAG models equipped with the same small-displacement turbo power unit

Reinforced Durable Structural Design

1. Glass fiber reinforced PA66 high-temperature plastic housing: Resistant to long-term high-temperature gas baking, oil corrosion and aging, not easy to deform or crack
2. Precision silicone one-way valve core: Stable opening and closing pressure, excellent sealing performance, effectively prevent gas backflow into crankcase
3. Integrated built-in anti-clogging filter screen: Block large oil sludge particles, prolong service life and reduce carbon deposition inside the valve body
4. Standard anti-slip hose connectors: Firmly locked with ventilation rubber pipes, no falling off under driving vibration
5. Complete with built-in sealing ring, effectively avoid air leakage at assembly position

Balance Crankcase Pressure & Protect Turbo Engine Overall

1. Timely discharge blow-by gas inside crankcase back to intake manifold for secondary combustion, lower exhaust emissions
2. Maintain negative pressure balance inside crankcase, prevent pressure buildup leading to oil leakage from crankshaft oil seals and gaskets
3. Avoid excessive oil mist entering intake channel, slow carbon accumulation on intake valves and cylinder
4. Eliminate engine whistling abnormal noise, stabilize idle operation and restore normal fuel economy

Fully Resolve Common PCV Valve Failure Symptoms

• Obvious whistling/squeaking noise when engine is running
• Engine idle jitter, unstable speed occasionally
• Increased engine oil consumption, obvious oil burning phenomenon
• Oil seepage around valve cover, crankshaft front/rear oil seal leakage
• Severe carbon deposit inside intake manifold, power decline and fuel consumption rise
• Excessive exhaust harmful substances, failing vehicle emission inspection
