Quick-Connect Coupling With Indication Pins
WARNING: This page is about a different car, the 2010 BMW 135i, 2009 BMW 135i, and 2008 BMW 135i. However, it is still accessible from the selected car via links, so may be relevant.
Removing:
Press plastic ring (2) into quick-connect coupling (1) and remove coupling (1).
Assembly:
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.
