Purpose and Compatibility

The presented starter is dedicated to 2.0 TFSI petrol engines in Audi A4 and Audi A5 models with CDNC and CDNB designations. By maintaining the factory housing geometry and correct positioning of the ring gear teeth, the component interacts with the flywheel in a predictable and safe manner for the drivetrain.

The starter is designed to operate within the high-current electrical system typical for TFSI units, ensuring reliable starting of both cold and warm engines. Original Audi construction minimizes the risk of fitting issues, mounting play, or incorrect engagement.

Construction and Performance Parameters

As a component from the Starters category, the product is responsible for initiating engine operation through a short, intense load on the electrical system. Its construction includes an electric motor assembly, a gearbox, and a coupling mechanism with the flywheel ring gear, ensuring efficient transfer of starting torque.

The starter is adapted for operation with petrol fuel, meaning it is calibrated for the compression characteristics and mechanical resistances of TFSI units. Stable operation under load limits voltage drops in the electrical system and reduces the risk of onboard electronics issues during startup.

Condition, Verification, and Installation

The component is offered as used, allowing for an economical starter replacement while maintaining the original manufacturer's specifications. Before installation, a standard check of the vehicle's electrical system (condition of ground wires, terminals, battery) is recommended to fully utilize the component's potential.

The starter is designed for installation at the factory mounting points in the engine block. This makes the replacement process predictable for workshops specializing in the Audi brand, and maintaining the original starting system architecture facilitates future diagnostics and servicing.

Benefits of Using an Original Audi Starter

• Factory fit for 2.0 TFSI CDNC/CDNB engines in Audi A4 and A5.
• Appropriate operating characteristics for direct-injection petrol engines.
• Compatibility with the factory electrical system and control.
• Reduced risk of starting problems compared to aftermarket alternatives of uncertain origin.

For users who prioritize maintaining consistency with factory specifications, choosing an original Audi starter is a technically safe and predictable operational solution.
