Restore smooth idle, proper crankcase pressure, and engine performance with the Borsehung Engine Crankcase Breather / PCV Valve.

Borsehung is a high-grade European automotive specialist offering genuine OEM-equivalent quality parts. The PCV (Positive Crankcase Ventilation) valve on VAG 1.8 and 2.0 TSI/TFSI EA888 Gen 3 engines is a key maintenance component. Over time, the internal rubber diaphragm cracks or the check valves fail, leading to rough idling, excessive oil consumption, oil cap suction, or whistle/squeal noises. Replacing your worn unit prevents oil contamination in the intake system and eliminates vacuum leaks.

Why Choose Borsehung?

• OEM-Matching German Standards: Built to direct factory specifications with heat-resistant Polyamide 6.6 housing and high-grade Fluoride Rubber (FPM) internal seals.

• Solves Common EA888 Issues: Fixes active fault codes (P0171 - System Too Lean, P0300 - Random Misfires), high oil usage, and surging idle.

• Pre-Assembled Design: Comes pre-fitted with the essential rubber valve cover gasket seal and mounting hardware for a direct, hassle-free replacement.

• Exact Pressure Control: Calibrated internal diaphragm precisely regulates blow-by gases and maintains optimal vacuum levels across all RPM ranges.
