32 41... Notes on hydraulic line with quick-connect coupling: Assembly
WARNING: This page is about a different car, the 2013 BMW 550i GT, 2012 BMW 550i GT, 2011 BMW 550i GT, and 2010 BMW 550i GT. However, it is still accessible from the selected car via links, so may be relevant.
Markings (K) on coupling (1) and pipe (4) must be flush.
Push quick-connect coupling (1) onto pipe (4) until a "click" can clearly be heard.
To check that quick-connect coupling (1) has been installed correctly, pull it back forcefully.
When replacing hydraulic line: remove transportation lock (T).
Push quick-connect coupling (1) onto pipe (3) until both indication pins (4) can be seen and felt to point outwards at outside diameter of housing.
To check that quick-connect coupling (1) has been correctly fitted, feel indication pins (4) at outside diameter of housing. When correctly seated, indication pins (4) cannot be pressed into housing.
IMPORTANT:
Coupling is not correctly engaged if both indication pins (4) fail to protrude from housing. Leakage is thus unavoidable.
