Purpose and Function in the Vehicle

The presented door lock is dedicated to the front right door of the Audi R8 generation 42. It is responsible for the mechanical locking of the door leaf and transmitting motion from the actuator to the latch mechanism. A correctly functioning lock guarantees:

• stable door closure when driving at higher speeds,
• proper cooperation with the central locking system and remote control,
• correct response to signals from the vehicle's electrical system.

Thanks to its factory design intended for a specific body model, installation is predictable, maintaining original mounting points and linkage routing.

Construction and Compatibility

The Right Front Door Lock for Audi R8 42 is designed as a complete unit with a locking mechanism and an integrated actuator. This means that after correct connection to the vehicle's electrical and mechanical systems, it can immediately cooperate with the factory comfort system.

As a component from the Locks and Latches group, it is structurally adapted to the door's geometry, sheet metal thickness, and the routing of external and internal handles. The use of an original solution allows for maintaining:

• the correct position of the striker relative to the pillar,
• the proper stroke of the handle and linkages,
• consistency with the factory settings of the comfort module.

Benefits of Using an Original Lock

Choosing an original door lock for the Audi R8 42 offers a range of practical operational benefits. The most important include:

• Factory Fitment – no need for modifications to mountings, linkages, or wiring harnesses.
• Vehicle Electronics Compatibility – correct cooperation with the central locking system, alarm, and comfort functions.
• Stable Mechanical Operation – proper door locking and unlocking, reduced play and rattles in the closing area.

A used part allows for an economical repair of the locking system while maintaining the original manufacturer's specifications, which is particularly important in sports cars where door fitment precision affects acoustic comfort and body rigidity.

Condition, Installation, and Service Recommendations

The offered lock is in used condition, allowing for a cost-effective purchase while maintaining the original manufacturer's specifications. Before installation, a standard check of the electrical connector, mounting points, and cooperating linkages and handles is recommended, as well as verification of correct operation in manual mode and with the central locking system.

During installation, it is worth paying attention to:

• the correct alignment of the lock with the striker on the pillar,
• the absence of excessive tension on the linkages and cables,
• the sealing integrity at the point where the wiring harness and mechanism pass through the door panel.
