The Audi S4 was formerly known as Audi 100 S4. It appeals to drivers with a high-quality vacuum pump. The Audi S4 vacuum pump is an important part of the vehicle, especially the ones that come with direct injection, or turbo engine. It is used in a vehicle where the intake manifold does not have enough vacuum pull.
The Audi S4 functions quite well in the beginning. However, the old vacuum pump might lead to poor functions and unpleasant driving experiences after years of usage. Components that use vacuum include a power brake booster, exhaust gas flaps, and EGR valves. A vacuum pump is mainly used in vehicles in which the intake manifold does not provide the necessary vacuum for the engine parts that need it.
