This OEM-grade 48mm throttle body (intake air control valve) is a direct throttle body replacement for Audi A4, A6, Q5, TT, VW Golf VI, Passat, Tiguan, CC, Scirocco, and Skoda Octavia/Superb with 2.0 TDI Common Rail EA189 engines. Engineered to VAG OEM specifications, it resolves common throttle body symptoms on TDI diesels — including EGR-related rough idle, loss of power, limp mode, and intake carbon buildup — restoring precise intake air control and engine response.
- OEM-Grade Throttle Body – Direct bolt-on replacement, no wiring modification required.
- 48mm Precision Bore – Factory-correct diameter for 2.0 TDI EA189 engines.
- Dual Redundant Throttle Body Sensor (TPS) – Prevents idle fluctuations, hunting, and false error codes.
- Throttle Body Gasket Compatible – Fits standard OEM gasket for a clean, leak-free seal.
- Stainless Steel Butterfly Valve – Corrosion and carbon-resistant for long service life in diesel applications.
- 100% Factory Tested – Thermal cycling, airtightness, and full-stroke angle calibration before shipment.
- Bore Size: 48mm
- Engine: 2.0 TDI Common Rail (VAG EA189)
- OE Ref: 03L128063A / 03L128063AF / 03L128063D / A2C59512935 / A2C53338105 / V10810063
- Housing: Die-Cast Aluminum Alloy
- Seal: Viton
- Warranty: 12 / 24 Months
Professional installation is strongly recommended. On 2.0 TDI EA189 engines, the intake air control valve (throttle body) is closely integrated with the EGR system. After fitting this throttle body replacement, clear all fault codes with a compatible VAG OBD scan tool and verify intake system integrity. Unlike petrol engines, TDI throttle body symptoms such as limp mode or black smoke are often linked to carbon deposits — inspect and clean the intake manifold during replacement for best results.
