34 33 071 Replacing vacuum hose for brake booster (N14)
Necessary preliminary tasks:
- Remove INTAKE FILTER HOUSING
- Remove LEFT COWL PANEL COVER (R59, procedure identical for R58)
Before beginning work, fully press the brake pedal several times to reduce the vacuum pressure in the brake booster. This makes it easier to detach the vacuum hose.
Disconnect quick-connect couplings (1).
Unclip vacuum line (2) from holder (3).
