xShop Now Genuine Bentley Breather Line Online – Part 07P103474L
The Genuine Bentley Breather Line 07P103474L carries blow-by gases from the crankcase to the ventilation system so they can be filtered and reintroduced into the intake for controlled combustion.
This is a real OEM Bentley breather line designed for a specific position in the W12 engine’s ventilation routing. The pipe features the correct internal diameter, reinforced wall construction, and precise end fittings to connect securely between the crankcase outlet and the ventilation circuit. Proper routing ensures consistent airflow and prevents leaks within the system.
Over time, exposure to engine heat and oil vapour can cause breather lines to harden or crack. When this happens, unmetered air may enter the intake system, which can lead to rough idle, lean mixture warnings, and increased oil consumption.
Replacing a damaged breather line restores proper crankcase ventilation. Buy genuine Bentley engine components from EuropeanAutoSpares for trusted quality, exact fitment, and reliable performance.

Why Choose EuropeanAutoSpare?
Genuine OEM Quality
This is a real Bentley crankcase breather line. The rubber compound and routing geometry match the W12 engine's crankcase ventilation system position exactly for sealed, correct blow-by gas flow.
Perfect Fit
No leaks, no forced routing, and no contact with hot engine surfaces along the original routing path.
Clean Cabin Air
A sealed breather line keeps crankcase gases within the closed ventilation circuit. Uncontrolled crankcase gas leakage near the engine bay can introduce oil vapour and combustion gases into the cabin fresh air intake path at the windshield base.
Full Climate Efficiency
This OEM rubber compound resists oil saturation and heat hardening in UAE engine bay temperatures.
Fast Delivery
EuropeanAutoSpare ships this genuine Bentley component fast to the UAE and worldwide with engine position and routing confirmation before your order ships.
Need Help Finding the Right Parts?
EuropeanAutoSpare uses your VIN to confirm this breather line is the correct routing specification for your Bentley model and engine variant. Multiple breather lines are used in the W12 ventilation system and each has a specific routing position.
Keep Your Bentley's Crankcase Ventilation Circuit Intact
A genuine Bentley Breather Line 07P103474L maintains a sealed, correctly routed crankcase ventilation path in your W12 engine. Replace a cracked or hardened breather line immediately and restore accurate MAF sensor readings and correct engine management function.
Fitment Details
xBentley W12 TSI High-Pressure Fuel Pump Fitment
| Bentley Model / Generation | Application Details (W12 TSI Platforms) | Year Range |
|---|---|---|
| Bentley Bentayga | 6.0L Twin-Turbo W12 TSI Models (Direct Injection System) | 2016–2020 |
| Bentley Continental GT | 6.0L Twin-Turbo W12 TSI (3rd Generation Platform Layout) | 2018–2024 |
| Bentley Continental GTC | 6.0L Twin-Turbo W12 Convertible (3rd Generation Platform Layout) | 2019–2024 |
| Bentley Flying Spur | 6.0L Twin-Turbo W12 TSI (3rd Generation Executive Saloon) | 2020–2026 |
Technician’s Advisory: The 3rd-generation W12 TSI powertrain utilizes two separate high-pressure fuel pumps to distribute fuel evenly across its unique multi-bank configuration. When replacing an HPFP, always install a brand-new mechanical roller tappet follower and a fresh viton sealing O-ring. Reusing a worn roller tappet can cause rapid mechanical scoring on the new pump's piston shaft or damage the specialized camshaft drive lobes. Because this system operates under dangerous pressures exceeding $200\text{ bar}$, the fuel system must be electronically depressurized via a diagnostic tool prior to teardown, and all high-pressure fuel line fittings must be torqued precisely to factory specifications to eliminate fuel weeping risks.
FAQs
xFrequently Asked Questions
Yes, this is a genuine Bentley OEM crankcase breather line (Part No. 07P103474L). It is manufactured exactly to factory specifications using advanced, heat-stabilized polymer materials designed to withstand intense engine bay heat cycles without cracking or becoming brittle over time.
While both components belong to the PCV (Positive Crankcase Ventilation) circuit, they perform different roles. The oil separator (07P103464L) physically extracts oil mist from the internal engine blow-by gases. This breather line acts as the dedicated conduit that transports those gases to and from the separator unit.
Common symptoms of a leaking breather line include an unstable or rough engine idle that worsens as the engine warms up, unmetered air leaks triggering lean mixture or Mass Air Flow (MAF) sensor fault codes, increased oil consumption, or an unburned oil mist smell filtering into the cabin during deceleration.
No, temporary repairs are highly unreliable. Crankcase ventilation pipes continuously alternate between positive and negative pressure thresholds based on engine loads. Temporary sealants or wraps degrade rapidly when exposed to hot oil vapors and vacuum pressures, leading to recurring unmetered air leaks.
Yes, European Auto Spares provides fast, fully-tracked express shipping straight to the UAE and worldwide. Every molded breather line assembly is secured in impact-resistant structural boxing to keep the pre-formed routing profiles and delicate end quick-release clips perfectly safe during global transit.
