VDO A2C59514305 — Throttle Body
Overview
Throttle body VDO A2C59514305 controls intake airflow volume into the manifold on 2.0 TDI diesel engines. The unit features an electric actuator operating at 12 V, an integrated position sensor, and a 4-pin electrical connector. Bore diameter measures 48 mm. Constructed from cast aluminium alloy, the housing resists high thermal loads and oil vapour exposure. The internal valve plate adjusts opening angles based on ECU control signals, maintaining steady idling and smooth transient response. OEM cross-reference numbers include VAG 03G128063R, 03G128063Q, 03G128063M, and 03G128063G. Mechanics select this unit to restore accurate air-fuel metering and smooth engine shutdown operation without vibration.
This throttle body fits Audi A3 8P, A4 B7, A6 C6, Volkswagen Golf Mk5, Passat B6, Touran 1T, Skoda Octavia A5, and Seat Leon 1P models equipped with 2.0 TDI engines (codes BKD, BKP, BMM, BMN) produced between 2003 and 2011. Replacement becomes necessary when internal plastic gears strip, carbon deposits bind the throttle plate, internal circuit faults trigger fault codes P2101, P0638, or P2102, or the actuator motor fails. Typical failure symptoms include harsh engine shutdown with heavy shaking, fluctuating idle speed, loss of power, hesitation under acceleration, and illumination of the Check Engine light on the instrument cluster.
