BMW 3 Series E46 . Body Door Anchoring System

Vehicle: Application and ID Door Anchoring System Door Anchoring System

Cross section of driver\'s door and \"B\" pillar in the normal closed position.

Upon severe impact, the hook locks into the recessed notch to provide a unitized side impact protection system.

After impact, the door springs back and unhooks the notch.

The door is clear of the \"B\" pillar and can be opened.

The door handles and locking system on the E46 are of a new design. The new bow type handles allow the doors to be opened easier. The locks are fully encapsulated including the electrical components. The new door handle/latch/lock assembly offers improved reliability and security against theft. The micro-switches for door position and lock condition have been replaced by hall sensors.











There are no serviceable components on the lock assembly and it must be replaced as a unit.
