The vacuum system of the engine S63 TOP has a few changes compared to engine S63.
The vacuum pump has a two-phase design so that the largest share of the generated vacuum is available to the brake servo.
The vacuum reservoir is now no longer placed in the V space but mounted to the bottom of the oil sump. The applicable vacuum lines were adjusted accordingly.
The graphic below shows the components of the vacuum system and their installation position.
