12V Solenoid Valve Boost Pressure Control Valve High-grade Thermoplastic Direct OEM Replacement for VW Beetle A5 1.4 TSI

Premium-quality direct replacement solenoid valve designed for Volkswagen Group vehicles with 1.4L TSI/TFSI EA111 turbocharged petrol engines.

An electro-pneumatic solenoid valve that controls the turbocharger's boost pressure. The ECU uses it to precisely regulate the turbocharger's bypass valve (N75/N249), preventing damaging compressor surge, ensuring smooth power delivery, and protecting the engine from over-boost conditions.
