06F103221E : Breather hose for Audi A3 (8P)

This breather hose is designed for the Audi A3 (8P), including the Sportback version, equipped with 2.0 200 hp (engine codes AXX, BWA), 2.0 256 hp (engine codes BZC, CDLC) and 2.0 265 hp (engine codes BHZ, CDLA) powertrains. The breather circuit ensures ventilation of the engine sump by returning blow-by gases to the intake, and a cracked or clogged hose can cause oil leaks, overpressure in the sump or performance degradation. As part of the restoration or maintenance of a classic vehicle, replacing this worn or damaged part helps maintain the sealing and proper functioning of the entire engine assembly. This new part allows you to restore original characteristics for careful restoration.
