Construction and Compatibility with Audi Models

The socket is designed as a component to be installed in factory mounting points, preserving the original interior layout. Its construction is intended for use with the 12V electrical system in Audi vehicles, eliminating the need for modifications or additional adapters, provided the installation is carried out as intended.

Its original Audi OE origin means that the housing geometry, mounting method, and electrical parameters are consistent with solutions used in the initial assembly. This ensures consistency with other cockpit and center console components.

Component Condition and Service Application

The offered socket is in used condition, making it a sensible choice for routine repairs or restoring the functionality of the 12V system without the need to invest in a new part. This type of component is particularly useful when the existing socket has suffered mechanical damage, overheating, or has lost stable connection with the plug.

Replacing the cigarette lighter socket is a typical service operation performed for issues with accessory power, intermittent charging, or loose connections in the socket. Using an original component helps to minimize the risk of improper fit and unwanted mounting play.

Choosing an original cigarette lighter socket for your Audi offers a range of practical advantages:

• Factory Fit – compatibility with the console structure and electrical system of the specific model.
• Consistent Interior Aesthetics – appearance and finish match the manufacturer's standards.
• Stable 12V Accessory Power – reduces the risk of contact overheating and unstable connections.
• Can be used for repairs or upgrades to cabin equipment.
