At its launch, the Audi S3 only was available as a three-door hatchback. Classic parts like the PCV valve hose lead to the success of S3. The PCV valve hose is engaged when the crankcase pressure rises in the engine when it is on. If a PCV valve hose somehow breaks, the gas won't reach the engine, and it can lead to an increase in emissions and poor fuel economy.
Whereas, the worn PCV valve hose parts need to be repaired or replaced for better S3 performance. It transfers the gasses from the crankcase to the PCV valve. The removal process for the S3 PCV valve hose is as follows. First, locate the PCV valve on the vehicle. Then disconnect the PCV valve hose by pulling the ends off the valve/engine side.
