The Audi A4 Quattro is a premium branch of the Volkswagen Group. Classic parts like the PCV valve hose parts contribute to the success of Audi. The PCV valve hose is engaged when the crankcase pressure rises in the engine when it is on.
Although A4 Quattro has lots of auto parts with impressive performance, its PCV valve hose parts still need repair and maintenance after a long time of usage. The removal process for an Audi 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 PCV valve side. The part should be replaced every 20,000-30,000 miles. There are plenty of inexpensive and quality Audi A4 Quattro products on our site.
