The second generation Audi S4 made its debut in 1997. Audi has manufactured plenty of quality vehicles and parts, such as the Audi S4 canister purge valve parts.

A faulty canister purge valve can cause the car to have poor fuel economy, a decline in engine performance, and the car to run rough.
Audi S4 functions quite well in the beginning. But the old Audi S4 canister purge valve parts might lead to poor functions and unpleasant driving experiences after years of usage. The canister purge valve parts allow the intake vacuum to send the correct amount of fuel vapor into the exhaust manifold. Signs of a faulty Audi S4 canister purge valve include less gas mileage and a check engine light on. Get helpful parts at a low price with just a few clicks.
