Installation must be performed by a professional. After fitting, a throttle body relearn procedure is required to recalibrate the throttle body position sensor baseline — this is standard throttle body service practice for VAG EA111 platforms. Non-professionals should not attempt installation, as improper fitting may result in throttle body malfunction. The instruction manual included in the package is for professional reference only.

Common throttle body symptoms on VAG EA111 1.2L / 1.4L engines include rough idle, hesitation on acceleration, unstable RPM at startup, and fault codes P0638 / P2135. If basic throttle body cleaning with throttle body cleaner spray has not resolved the issue, a full throttle body replacement is typically the next step.
This throttle body assembly includes an integrated throttle body position sensor – no separate sensor purchase required. A replacement throttle body gasket (VAG 037129717B or equivalent) is recommended and sold separately.
Compared to dealer throttle body repair cost (often $300–$600+ at a VAG dealership), this direct OEM-quality unit offers significant savings while maintaining factory performance standards. Fits VW Polo 9N/9N3, Golf IV, Bora, SEAT Ibiza 6L, SEAT Leon 1M, and Škoda Octavia 1U with EA111 1.2L 12V or 1.4L 16V naturally aspirated engines.
Note: Throttle body adaptation via VCDS/VAG-COM Basic Settings Group 098 is required after installation. The throttle body gasket is sold separately.
